9SESAME JSPS Workshop - First USERS meeting 27
October 2002
10- JSPS meeting was an excellent platform to refine
the science case and define the phase one
beamlines. - This was the first meeting of the committee
members (Science Beamlines), even though
incomplete (7 out of 12). This brought together
the USERS communities and members of the Beamline
and Science Committees since the establishment of
SESAME as a UNESCO project. - 1. We need to establish
- USERS requirements for Source
- Types of Experiments you envisage
- Types of Samples you are interested in
- Environmental Chambers
- Draw up Phase one and two beamlines up to ten
- 2. We need to identify
- Champions for each beamline ideally two to
three people - Sources of funding
- 3. We need to start a training programme for
item 2 as soon as possible.
11- Potential First Phase Beamlines
- (Potential Champions identified)
- MAD Protein Crystallography beamline for modest
size unit cell (6-14keV) - High Resolution, large unit cell Protein
Crystallography beamline (10-12keV) - SAXS and WAXS for polymers and proteins (10keV)
- Powder Diffraction with extreme environment
(20keV) - Chemical (small molecule) Crystallography (14keV)
- Photoelectron Spectroscopy of gases and solids
(100-1000eV?) - Spectromicroscopy (300eV-3keV?)
- Magnetic X-ray CD (300eV-12keV?)
- IR Spectromicroscopy (Sub-Micron to Micron?)
- UV CD for Biology
- XAFS (3-20keV)
- Micro-Diffraction
12Comparison of SR from Wigglers of SESAME, ALS
(Berkeley) and SLS (Zurich)
Thus at 10keV there is little difference between
ALS and White Book SESAME

15- Joint Committees Key Recommendations
- Accepted by the Council
- (a). Machine Energy
-
- Exploring the option of a 2.5 GeV machine, with
2 in-vacuum undulators, and seek assistance in
the implementation from Japan where In-vacuum
Undulator technology has been pioneered. - Exploring the option of running a 2.5 GeV
machine at 2 GeV, if that is needed for
Ultra-high resolution VUV and SXR experiments. - (b). Full Energy ( Top-up) Injection
- Building the inner shield wall with enough space
so that a full energy injector system can be
incorporated as and when funds become available
in due course. This is seen as an URPGRADE
perhaps after 3 to 4 years of operation.
16- Joint Committees Key Recommendations
- Accepted by the Council (contd.)
- c). BEAMLINES
- From a total of 12 beamlines discussed at the
SESAME USERS meeting, 6 beamlines were
recommended for Phase one with the next tranche
of beamlines following very closely. - d). Training REQUIREMENTS
- There are two types of requirements
- one where station and beamline scientists and
engineers are trained so that beamlines can be
built and commissioned. - The other is where inexperienced users work with
the experienced users so that SESAME users
community grows in experience, and as such would
be ready for utilizing the source when it is
built.
17SCIENCE CASE REFINED AND UPDATED Science Areas
for SESAME
18Main Techniques Used by these Science Areas
Some of the techniques are common to several
scientific discipline - provision of these would
attract a very wide users base. In contrast some
techniques, even though used by one discipline,
e.g. Protein Crystallography, has a large users
base both internationally and in SESAME
countries.
19Phase One Beamlines
This could be a split beamline and in phase 2
could be developed on separate Ids depending on
the growth of community.
20Candidates for Phase II Beamlines
- Potential users are encouraged to come together
and form critical mass. Science Case would need
further development. - Champions need to come forward and sources of
funding need to be identified.
21SESAME Lattice - Relatively small circumference
but high used by IDs.

29Working Group on XPS, XAS in The Soft x-ray Region
- A Multipurpose Phase I Beamline
- At SESEAME
30Minutes of the discussion session
- After a short introduction about the format of
the discussion and a description of the
specification of the proposed multipurpose
beamline, the participants were invited to - present their interests and identify a group of
other researchers working in a closed field. - Identify, if possible their expectations and
needs as far as the beam properties are
concerned.
31Atomic and Molecular Physics group
- 100 900 eV
- R 10000
- An atomic and molecular spectroscopy group was
identified and was asked to start discussions
about possible collaboration among each others
AND about ways to build a gas phase experimental
chamber.
32High Temperature Superconductors
- Several groups in the region are active in this
field Iran, Jordan, Pakistan, UAE. - XPS and XANES techniques will be used in the soft
x-ray region (O k-edge, Cu L-edge, .) - Magnetic materials (MCD), UAE, Oman, Jordan,..
33 Multipurpose
- The beamline would be very useful for
multipurpose investigation in environmental
sciences, nano-particles, archeological studies,
as it provide information about important
elements such as O, C, Fe, Cu, Mn, S, Si,
(L-edges), Ru,.. - Luminescence station would be useful
34Notes from discussion on Diffraction and EXAFS
SESAME beamlines The sciences affected by the
operation of these two Phase I beamlines
are Environmental Science, Materials Science,
Archaeology and Structural Biology. The 3-30keV
energy range envisaged for the two Wiggler
beamlines covers the interests of the
corresponding communities with flux density and
energy tunability being the primary
concerns. EXAFS capability is required by all
four science areas represented in this meeting.
The energy range afforded on this beamline is
optimal and covers most of the key element
edges. The powder diffraction beamline is
required to have the capability for small
footprint (100-50microns) and fast area detection
(image detector) in addition to SSD 2theta-scan
detection for high angular resolution. Ancillary
equipment for mounting samples in flat-plate
geometry or for spatial resolution using x-y
stages is required as well as provision for
environmental chambers and equipment for
time-resolved experiments, e.g. low/high
temperature furnaces (10-1000C).

38Second Joint Beamline and Science Committees
meeting, UNESCO, Paris - 15-16 April 2004
39- Key Recommendations from the 2nd Joint committees
meeting - Two 5-6m long straight sections,
- Two In-vacuum undulators (3m ID) for 8-12 KeV
X-rays, - Two large opening (40-45 mrad) bending magnets,
- Longer beamlines to be reserved where the extra
length is intrinsically required by the
experiments, - Beamlines should be grouped physically
according to their primary scientific community
to provide optimum users support and access to
local off-line laboratory facilities, - Space in the building is at a premium and should
be reserved for scientific and technical
functions for the facility, administrative
facilities (including directorate) should be
located in the neighboring building, - Third SESAME Users meeting to be held in Turkey,
October 2004, - Training of Beamline Scientists for Phase one
beamlines to start immediately, increased
coordination with training committee.
40- Scientific and Technical Expertise Are Required
in the following areas - Mechanical and Electrical Engineers (Design and
Assembly of Beamlines), - Computer Scientists (Data Acquistion, Data
Analysis Automation), - Core Science Expertise for Phase One Beamlines
(Physicist, Chemists, Biologists, Material
Scientists etc.) - QUALITIES
- Ability to work in a team and in particular
international teams. High level of Motivation
Dedication to achieving excellence as only this
would help achieve excellence and international
standing of SESAME as Science, research,
Innovation and Discovery of centre.
41- Science and technology are cyclical. They are a
shared heritage of all mankind. East and West,
North and South have all equally participated in
their creation in the past, as we hope that they
will in the future the joint endeavor in
sciences becoming one of the unifying forces
