LHC Physics Center LPC at FNAL

LHC Physics Center (LPC) at FNAL
Sarah Eno US CMS Meeting, Princeton 30 Apr 04

What is the LPC?
An attempt to reproduce the benefits of being at
the lab in our time zone, on our side of the
Atlantic.

• a critical mass (clustering) of young people who
  are actively working on software (reconstruction,
  particle identification, physics analysis)
• one stop shopping for your analysis questions
• analysis tools such as large meeting rooms,
  video conferencing, large scale computing, water
  cooler
• virtual control room for active participation in
  the running and quality control of the experiment

History

• First proposed in 1999 by Dan Green at a US CMS
  meeting at Cal Tech
• strong support by US CMS expressed through email
  survey

• luke warm support by FNAL management. (Green et
  al. did manage to get 11th floor for this center,
  though)
• luke warm support by funding agencies
• not much active involvement by US CMS in
  planning/implementing (not even clear how an
  interested person would go about getting involved)

Recent History (Spring 2004)

• Lab now strongly supports it

• Funding agencies starting to support it

• More people involved
• Kaori Maeshima infrastructure, remote control
  room
• me, Avi Yagil local analysis groups
• Heidi Schellman workshops, users organization

Lab Support
We are (finally!) getting good luminosity at the
Tevatron! Expect a flood of Tevatron PRLs this
spring!
But, the experiments are currently undermanned.
And, the universities are not getting increases
in postdoc funding. So, postdocs for LHC must
come at the expensive of the Tevatron.

Letter from Tevatron Groups
A group of 9 University faculty on D0/CDF and CMS
wrote to Mike, asking that he strongly support
the LPC during the coming 3 years
(2004,2005,2006) because we saw no other way we
could possibly maintain the level of manpower we
need on the Tevatron experiments while insuring
we will be ready to do physics on Day 1 on the
new energy frontier machine (LHC).
Sold LPC as a way to ensure a smooth transition
between Tevatron/LHC and to maintain manpower on
the Tevatron experiments as LHC turn-on becomes
imminent. As a way to allow postdocs to work on
both experiments at the same time.

From the Lab
The 11th floor
Avi Yagil

• well known analysis/software expert from CDF
• former head of CDF offline
• very enthusiastic about being part of the LPC

3 postdocs this year, more in the future

Letter
Dear Colleagues   I am writing to respond to
your letter concerning the LHC Physics Center at
Fermilab. In that letter you expressed interest
in the development of such a center and stated
how important it would be for U.S. university
groups to take full part in research with the CMS
data sample.   Both Fermilab and the leadership
of the US-CMS research program have also
expressed support for the LHC Physics Center
(LPC) . One goal of the center is the one you
articulated, that is, to make it possible for
U.S. physicists working on CMS to be innovative
leaders in LHC physics. The other is that
Fermilab remain an intellectual center for
collider physics in the LHC era. I think that
both of these goals serve the larger purpose of
advancing particle physics in the U.S.   A broad
group of the involved parties recognizes the need
of a transition period in which physicists will
share effort between CDF or D0 and one of the LHC
experiments. This sharing will make it possible
to sustain the needed effort to operate CDF and
D0 effectively, at the same time that it brings a
lot of experience from the Tevatron program to
the LHC. At our Annual Program Review, both CDF
and D0 said that they are moving to make it
easier for scientists to be an active member of
their collaborations while sharing time with CMS
or ATLAS. P.K. Williams expressed to me his
encouragement of the LHC Physics Center here as
an effective way of sharing university physicists
between CDF or D0 and CMS. I want to make the
LHC Physics Center into one of the leading
centers in the world for producing particle
physics results, and am ready to commit resources
to that end. In planning this startup we will
work closely with you and with leadership of the
US-CMS research program to make sure that we are
establishing an institution that serves all of
the interested parties well.

  We plan to increase Fermilab staffing for CMS
computing and analysis. We will work to provide
the appropriate level of support from computer
professionals. We would also like to attract a
few Research Associates with primary assignment
to CMS over the course of the next year. In
addition, we should be able to attract a Wilson
fellow to CMS, a position that is at the level of
an Assistant Professor. Finally, we are
emphasizing the importance of this effort by
having Avi Yagil invest a large part of his time
in making it work. We have encouraged him to
attract additional help from Fermilab scientific
staff on CDF and D0.   We hope that this
initiative will help Fermilab to take a role in
CMS and LHC physics that is larger than remote
laboratories have been able to do on previous
experiments. The benefits of doing so will be
large for Fermilab and for the U.S. physicists
working on CMS.   Sincerely,       Michael
Witherell

Lab Support
Have also met personally with Mike, and feel sure
he supports it.
Presented in spring reviews of FNAL, and was
favorably received by funding agencies with this
slant.

Now

• 3 main efforts
• Workshops and Users Organization Heidi
  Schellman
• 11th floor infrastructure and remote control
  control room Kaori Maeshima
• On-site analysis groups plus Avi Yagil and me

12
11th floor

• Survey (by me) to try to understand patterns of
  use (transient versus permanent resident)
• Spoke directly (on phone) to 34 universities
• Still playing phone tag with 3
• Unable to make contact with 3

• Common concerns
• Flat budgets, current obligations
• Not enough students, post-docs
• Transition from present engagement to CMS
• Commissioning period Vs. steady state operation,
  analysis

Once again, surprised by the strong degree of
support!

Results
Will your university have somebody stationed
permanently at the lab, working on software on
the 11th floor, in the years

• Year probably hopefully
  
• 11 1
  30
• 11 11

• 9 18

Please think about this. If this is not a
powerful center before LHC turnon, I dont think
it will go.
14
11th floor
(Kaori Maeshima)

• high speed internet access
• transient area on cross over
• lockers for transients
• 1 large and 2 small meeting rooms
• secretary support, printers, etc
• Italian espresso machine
• remote control room
• offices for permanent workers

Trying to understand appropriate balance between
transient and resident areas. Can not afford
wasted space, but want everyone to be comfortable
Your input is needed!!

11th floor
Great view!
Major infrastructure work will be done this
summer. Ready for occupation this fall.

Local Experts
Avi and Sarah
An espresso machine and a nice view are not
enough to make it efficient for people to work
part time on Tevatron and LHC.
Its not enough to keep people coming to FNAL,
stationing people at FNAL, after LHC turnon.
This center will only be an exceptional analysis
center, and fullfill its mission to help US HEP
during the next critical 3 years, if we develop a
strong, well-coordinated, group of local
expertise.
17
Local Experts

• calorimetry/jets/met
• muon
• e/gamma
• tracking
• trigger
• simulation
• framework code/tools

Want to develop strong local expertise in all
areas of reconstruction, particle ID
Working within PRS groups, but clustered
physically at FNAL, doing coordinated work
Trying to find 1-2 contact people/conveners per
topic, to organize a group working in each area
at the lab. Welcome your input!
18
Local Experts
Goal for summer find people willing to fill
these slots (including 3 FNAL postdocs), and
spend the summer just learning what exists, how
well it works, etc
Expect to start actively working in PRS groups in
fall.
19
Local Experts

• Tracking Kevin Burkett (FNAL, Wilson Fellow),
  Sasha Khanov (Rochester) co-conveners/local
  experts
• Have been holding weekly meetings (Tue
  1300-1600)
• Learn how to Simulate, Run, Look at output,
  Study performance
• Generating many questions to follow-up on.
• They will also participate in defining the
  trking wkshop.
• More manpower needed! Let us know about yourself

Infrastructure/Tools Elizabeth Sexton-Kennedy
and Hans Wenzel Trying to understand issues
related to local - code management -

Future
I think the future of the LPC depends on what we
do in this time when we are setting the LPC up.
The hardware part is set.
We need strong, local expertise at the lab.
Or, all the fancy hardware will go to waste!
Expect email soon from us on conveners names,
meeting times for local analysis groups
(afternoons US time!!!) Please participate.
