Preparation of the JINR Programme of Particle
Physics Research for 2007 - 2009 in line with
the main Provisions of the Road Map
In the past year the central directorate and the
directorates of laboratories aspired to bring to
conformity the Research plans with the JINR Road
map and to concentrate our limited resources on
the most perspective themes and Projects R.

Reasons for improvements

• New approach to the Topical Plan of Research of
  the JINR
• -N. Russakovich

• The Topical Plan has been significantly
  overloaded last years. Too many topics have been
  recommended for implementation by PACs and
  Scientific Council, mainly due to the absence of
  clear guidance from budgetary limitations (56
  topics in total). This resulted in chronic
  under-financing of some projects and consequently
  to decreasing the realization of those projects
  and/or continuous extension of their lifetime
• The traditional Topical Plan, although been
  updated on the yearly basis, doesnt contain
  clear milestones which could be followed up,
  even in the event all resources requested are
  provided in due time
• Substantial part of the budget (about 0.8 M) has
  been (and still is) allocated every year as
  Grants of Plenipotentiaries of Member States
  and Joint Programs between JINR and Member
  States, which leads in reality to a more or less
  flat distribution of those resources between
  topics, with no strong correlation with the
  priorities established by the PACs and the SC
• Continuous deficit of resources motivated some
  JINRs researchers to find additional jobs,
  external contracts etc, while keeping permanent
  positions at JINR and consuming infrastructure
  resources

4
Guidance's from JINR directorate to Laboratories
Directorates and Project Leaders

• The assessment of the significance of research
  themes and projects should be based on the
  strategic plan (road map) of JINRs development.
• The topical plan should include only those themes
  and projects, which can be fully financed in a
  timely way from the JINR budget. A 3-year plan of
  research, including clear milestones, will be
  required for each theme/project . Also the
  3-years cost profiles, coordinated with
  collaborating organizations, are obligatory.

5
Guidance's from JINR directorate to Laboratories
Directorates and Project Leaders (2)

• Research projects with a small number of
  participants from JINR (less than 5 full-time
  equivalent/FTE) and/or with a low level of
  financing from the JINR budget (less than 5
  KUSD/FTE per year) as a rule, would not be
  included to the Topical Plan.
• The Directors of the Institute Laboratories will
  be given the opportunity to use up to 10 of
  their respective laboratory budget under the
  corresponding budgetary items for supporting
  low-cost activities of promising nature, with a
  simplified procedure for the approval of
  projects. Merging of several projects in order
  to reduce the (total) number of projects in the
  Topical Plan is not accepted.

6
Guidance's from JINR directorate to Laboratories
Directorates and Project Leaders (3)

• Projects of construction (upgrade) of basic
  facilities should be submitted in the form of
  schedules indicating the scope of work, terms of
  execution and cost estimates. In planning several
  options for such projects, the assumed
  decision-making points should be emphasized. The
  exploitation costs are specified in a separate
  category.
• The administrative and financial management of
  themes and projects by persons after reaching 65
  years of age will not be allowable beginning
  2007.
• The support of innovative projects from the JINR
  budget is allowable for a term of not more than
  one year subsequently these can only be financed
  from non-budgetary sources.

7
A comment by the PAC on the Directorates
continuing effort to streamline the JINR
particle physics program

• JINR Chief Scientific Secretary, N. Russakovich,
  informed the PAC about the Directorates
  intention to implement a new approach to the
  contents and the template of the JINR Topical
  Plan of Research and International Cooperation.
  This approach, based on three-year planning, is
  intended to be fully consistent with the actual
  limitations of the JINR budget.
• The PAC congratulates the JINR Directorate on
  progress made towards streamlining the particle
  physics program of the Laboratory an on
  establishing milestones against which progress
  can be tracked each year.

PAC Chairs comment

• The physical construction for the LHC carried out
  by JINR has been a stunning success
• It is time now to turn to science-that is
  happening for the ATLAS, CMS, and ALICE teams
• Lingering concern over whether the computing
  infrastructure is scoped sufficiently to allow
  robust program of remote scientific analysis

Development of new superconducting magnets for
rapid cycling heavy-ion synchrotrons and beam
transport channels (A.Kovalenko)
Superferric 1 Hz dipole and quadrupole magnets
The works are performed within the RD
program on the design the SIS100 synchrotron at
GSI in Darmstadt. The investigations of 2 T
superferric 1.4 m model dipoles operating at 4
T/s, 1 Hz were completed. The main research
goal, namely minimization of overall AC power
losses in the magnet at 4 K level was reached.
The AC losses were reduced by a factor of two for
both as dipole and quadrupole magnets. The new
stage of the JINR/GSI collaborative work is
construction of a full length dipole (about 3 m )
and quadrupole (about 1.1 m) with the SIS100
specified apertures. The work is in progress.
The results were presented at the EPAC06 and
ASC06 Conferences. Artistic view of the new
magnets inside cryostats is presented in Fig.

LIT group activity for CBM (V.Ivanov)
Problems arisen due to two future alternative CBM
projects electron or muon physics
What has been done

1. Flexible tracking software developed for studying
   features of both STS-MVD designs. Momentum
   evaluation gives 1 level of accuracy
2. Two versions of TRD tracking developed STS based
   and standalone

• New magnet design
• Software development for STS and TRD tracking
• Tracking for new design of STS and MVD two
  versions
• Tracking for TRD two versions STS based
  (STS?TRD) and standalone
• RICH ring-finding
• Problem of effective rejection of fake and clone
  rings (2D parameter cuts, neural network
  approach)
• Study of two alternative RICH constructions based
  on Protvino photomultipliers (40 hits/ring) or
  Hamamatsu photomultipliers (22 hits/ring)
• RICH ring fitting and electron-pion separation

An original TRD 10 layers (4-3-3) design was
proposed which looks most optimal for both
versions. Efficiency for standalone tracking

One of advantages of the Kalman filter based
tracking algorithms is that they are easy
adaptable to various STS and TRD designs
18
LIT group activity for CBM (continue)
3. RICH ring-finding 7 different parameters were
taken into account to characterize any found ring
and applied for effective rejection of fake and
clone rings. Comparative study of two
approaches 2D parameter cuts or neural networks
(NN) showed the NN method advantage.
Its efficiency to reject fake and clone rings is
90. However despite of a few percent loss in
efficiency for electrons the gain is 17 times
less fake rings and 6 times less clone rings
NN output
Study of two alternative RICH multiplier
constructions Hamamatsu yield to Protvino only
10 in efficiency, but gives less fake rings and
no clones 4. Ring fitting and e -p separation
After comparison of several ring fitting
algorithms the best one was put into CBM
framework. Neural net was successfully applied
for most effective suppression of the pion rate

Project PAX
Collaboration PAX proposed experiments with
polarized antiprotons. For this purpose a
dedicated facility at FAIR to polarize an
antiproton beam could be built.
Scientific program studies in the field of
high energy spin physics
with use of a polarized
antiproton beam Main goal measurement of the
transversity distribution, the last missing piece
of the QCD description of
partonic structure of the nucleon.
Transversity describes distribution of
transversely polarized quarks
inside the
transversely polarized nucleon. Unlike
the well-known unpolarized distribution
q(x,Q2) and partly known helicity distribution
Dq(x,Q2), transversity
hq1(x,Q2) has never been directly
measured. Transversity distribution is directly
accessible uniquely via the double
transverse spin asymmetry ATT in the Drell-Yan
production of lepton pairs phph g ll-X Other
topics electromagnetic form factors (phases in
the timelike region,

GE-GM separation, )
single-spin asymmetries (Sivers
and Collins mechanisms, )
p-pbar hard scattering mechanisms
21
Recommendations on Major Future Projects

• Facility for Anti-proton and Ion Research (FAIR)
• The PAC considers this activity very important
  for JINRs future particle physics program
• With the process now ready to begin to determine
  JINRs real participation in the construction, it
  is very important to insure that all aspects of
  JINRs activity will have high scientific
  visbility and impact. This may well require
  concentrating available resources on selected
  aspects of FAIR as opposed to participating
  broadly in all areas of interest.
• The PAC looks forward to receiving additional
  information on the main areas of scientific
  activity at FAIR at its next meeting

The ILC linear accelerator is proposed to be
placed in the drift clay at the depth of 20 m (at
the mark of 100.00 m) with the idea that below
the tunnel there should be impermeable soil
preventing from the underlying groundwater
inrush. It is possible to construct tunnels of
the accelerating complex using tunnel shields
with a simultaneous wall timbering by tubing or
falsework concreting. Standard tunnel shields
in the drift clay provide for daily speed of the
drilling progress specified by the Project of the
accelerator (it is needed for tunnel
approximately 2.5 ys).
27

• Advantages of the ILC construction in Dubna
• The presence of JINR as a basic scientific and
  organizational structure. JINR is an
  international intergovernmental organization,
  which includes 18 Member States and 4 States,
  which are associated members.
• The proposed territory is extremely thinly
  populated and practically free of industrial
  structures, rivers and roads. The proposed
  placement of the accelerator tunnels in
  relatively dry drift clay excludes the influence
  on abyssal distribution of the underwater.
• The area is absolutely steady seismically and has
  stable geological characteristics.
• A flat relief and the unique geological
  conditions allow one to place ILC on a small
  depth (about 20 m) and to perform construction of
  tunnels, experimental halls and other underground
  objects with the least expenses, including open
  working.
• The extremely attractive feature of placing the
  ILC complex on the chosen territory is a unique
  opportunity to solve the problem of value at the
  purchase of land. Prevalent legal practice makes
  it possible to get the land of the ILC location
  to permanent free use just as it has been done
  for JINR, according to the agreement between JINR
  and the RF government.

28
6. There are sources of the electric power of
sufficient capacity in the area of the ILC
construction transmission line of 500 kV, the
Konakovo electric power station (EPS) and the
Udomlia atomic power plant (APP). 7. The
developed system of transport and communication
services, advantageous location, good highways
and railways, water-way (the Volga river basin),
good position in the European region 8.
Presence of a modern network and information
infrastructure, including one of the largest
center in Europe the Dubna Satellite
Communication Center. 9. A special the economic
zone established in Dubna in December, 2005
provides preferential terms for development and
manufacture of high technology technical
production. 10. Dubna has a powerful scientific
and technical potential. The developed
infrastructure makes it possible to involve
additionally specialists from world scientific
centers into the already formed international
collective of highly-qualified scientific
manpower providing comfortable conditions for
them to work. This guarantees a high quality of
investigations on ILC and obtaining of new
research results of fundamental scientific
importance.

  presented by G. Skirkov on plans for JINRs
  participation in the International Linear
  Collider project, including technical work that
  has been accomplished to substantiate the
  possibility of JINR hosting the ILC in the area
  of Dubna. The PAC strongly supports the intention
  of JINR to participate in this project and
  encourages the JINR team to become centrally
  involved in ongoing activities focused on plans

The physics program
1. The nuclear matter equation-of-state at high

3. Space-time evolution of nuclear
interaction. 4. The first order deconfinement

transitions. 5. The QCD critical endpoint.
40
Conclusion of Round Table Discussion   The
proposal presented, based on just a couple of
months of intense activity at JINR, together with
the ensuing discussions at the Round Table
meeting, has revealed the possibility for the
Joint Institute to host a competitive Flagship
project comprising challenging programs of
particle physics experiments and accelerator
science and technology. The basic concept appears
to be sound, but to ensure success the proposal
requires some further study and iteration to
ensure feasibility. The teams should be
encouraged to merge and to continue these studies
along the lines suggested above, and in the
earlier written reactions to the proposal. The
updated and extended version of the project may
then be submitted again for appraisal by a
selection of external experts if the JINR
considers it to be necessary.

41
Nuclotron facility development (the long(er)
term perspective)

• Accelerator/experiment options under
  discussion
• 1. Synchrotron with a beam energy of up to 10
  AGeV, beam intensity of Au/Pb/U ions more than
  106/s, internal fixed target.
• 2. Collider with c.m. energy of ?sNN 7 GeV
  (equivalent to a fixed target energy of about 24
  AGeV) and luminosity of 1027cm-2 s-1
  (corresponding to a reaction rate of 6 kHz for Au
  beams).

42
The Conclusion
The collider option permits to scan a larger
region of the QCD phase diagram, and is
preferable with respect to the fixed target
option.
The project has to be realized within 5-6 years
in order to be operational well before the FAIR
project. This boundary condition limits the size
of the project and restricts the technology of
the accelerator and of the experimental setup to
available solutions.

Recommendations on Major Future Experiments

• Nuclotron
• The PAC is concerned that carrying out this
  programme on the timescale indicated will require
  a major commitment of manpower and resources on a
  scale much larger than that allocated for
  operation and development of the Nuclotron in
  recent years. The PAC strongly recommends the
  creation of a fully developed, resource loaded
  project plan which shows how the programme will
  be carried out, how it will be financed, and the
  schedule for its completion.
• The PAC recommends that in the future, assuming
  the project to upgrade the Nuclotron moves
  forward, there should be further effort to
  convene the international scientific community
  which may potentially use this new facility to
  discuss ideas for experiments and detectors which
  may be part of the experimental programme.

47
Recommendations on Major Future Experiments

• Nuclotron-M
• The PAC recognizes the importance of this upgrade
  for the ongoing and future particle physics
  program at JINR, and feels that every measure
  must be taken to insure its successful
  completion. To that end, the PAC strongly
  recommends the creation of a resource loaded
  project plan which shows, in detail, the cost and
  schedule for this project as well as the
  resources to carry it out. This plan should be
  reviewed by an independent, expert committee,
  charged with assessing the robustness of the plan
  to successfully accomplish the planned upgrade.
• The PAC looks forward with interest to a report
  by the proponents on the full proposal, and to a
  report by the Chairperson of the independent
  expert panel at its next meeting.

• Apologies to LIT and BTLP as a short summary the
  PAC appreciated the reports of V. Ivanov and A.
  Sorin. The LIT and BLTP programs making very good
  progress.

Conclusions

• JINR has a vibrant, world-class program of
  particle physics which is ongoing in the near
  future a watershed of exciting new physics will
  pour out of the LHC. JINR is reasonably
  positioned to help lead the way on this new
  frontier but continued emphasis on scientific
  analysis and computing infrastructure to solidify
  its leadership role in the scientific analyses at
  the LHC is essential.
• Exploratory studies in major future experimental
  programs have positioned JINR well to continue
  its leadership role in particle physics into the
  next decade and beyond
• The reforms being implemented by the Directorate
  to streamline the particle physics research
  program and to further elaborate an integrated,
  strategic plan which realistically accounts for
  available resources will be central to the
  success of the JINR program in the future.

The Committee recommends that the physics program
for the new facility be extended to include an
outline of tasks beyond the initial 3 to 5 years
of running the collider, as well as indications
of a program for the fixed target physics
potential that will become available with the
facility. It recommends that the installation and
commissioning of the accelerator equipment be
staged to allow experiments to be made on fixed
targets with the increasingly intense and
energetic heavy ion beams as they become
available. It recommends that the two accelerator
groups and the two detector groups should merge
into single groups to continue the preparatory
work on the proposal. It also recommends that
where appropriate the expertise of other
laboratories, such as IHEP, ITEP, INR RAS and
BINP, be called upon to help solve some of the
problems related to the accelerator system and to
collaborate on the design and manufacture of
equipment.   The Committee endorses the
intention of JINR to organize this program as a
goal-oriented project. It would also advise the
incorporation of intermediate goals corresponding
to the stages, at which time stock should be
taken as to progress towards the achievement of
the final goal, and, if necessary, decisions
taken as to the eventual modification of that
goal. The first goal should be to achieve the
design performance of the Nuclotron. The
estimates of manpower requirements for the
accelerator program appear to be correct those
for the experiment do not seem to allow
sufficient manpower for simulation work. It is
difficult to appraise the cost estimates at this
early stage. For some equipment, notably the
booster, it seems to be low, and the cost
breakdown lacks entries for other essential
items. It would be advisable to make a more
complete cost breakdown, to be agreed upon
internally at JINR, containing the major items of
each system both in the proposed accelerator
complex and for the experiment.

Round table discussion IIOctober 6-7, 2006

• NUCLOTRON can become competitive facility at
  reasonable time scale
• Experiments with relativistic heavy ions can
  attract the international community searching for
  the creation of mixed phase
• Polarization experiments at modernized Nuclotron
  with sufficient intensity are also highly
  competitive
• JINR Directorate is taking organization measures
  to realize the Nuclotron modernization programme

61
Spin-filtering mechanism has been proposed in
order to polarize an antiproton beam initially
unpolarized circulating beam becomes polarized
via interaction with internal polarized hydrogen
target due to different interaction cross
sections for opposite antiproton
spin orientations.
Polarization build-up using spin-filtering
mechanism has been demonstrated in the only
experiment (FILTEX, 1993) with a proton
beam. For antiprotons the method still has to be
tested.
Unpolarized anti-p beam
Polarized H target
Physics program of PAX has been highly recognized
by QCD-PAC at GSI. It was stated that PAX will
become a part of the FAIR core research program
once the required luminosity and high degree of
antiproton polarization are demonstrated.

Documentation and Cost Estimation
July 2006 (for Vancouver GDE) JINR prepared and
filled the necessary documents for possible ILC
hosting to BCD (Conventional Facilities part), so
called Site Assessment Matrix.

• Official document from Russian State Project
  Institute (RSPI, Moscow) with estimations on
• Conventional facilities cost
• Siting (tunnel, land acquisition) cost and
  time schedule
• Energetic and power cost
• Operational cost
• Labor cost

The overall value on consolidated estimated
calculations in the prices of year 2006 for civil
engineering work, underground and surface objects
of the main construction gives the sum in order
of 2,3 B, including 1 B of costs of the tunnels
construction for linear accelerator, all its
technological systems and mines. Cost of power
supply objects which will provide electric power
directly from generator sources with special
(favorable) cost of energy (tariff) is of order
of 170 M.
November 2006 (for Valencia GDE) JINR prepared
and filled the necessary documents as a sample
site for possible ILC hosting to RDR (Work
Breakdown Structure - WBS) in a special
required format with all the details
on infrastructure parts. This document was also
prepared with RSPI and submitted by Design Cost
Board of GDE.
