Summary

3. Scope and Goals
The X-Ray Endstation Systems (XES) group will create the infrastructure required for experimenters to make best scientific use of the LCLS radiation safely
XES will equip a complete instrument for Atomic Physics Experiments
Coordinate all safety related aspects for the user environment and the experiments

4. The Endstation Systems will provide:
Infrastructure for LCLS Experiments:
Personnel protection systems (PPS)
Protect people from x-rays and lasers
Machine protection systems (MPS)
Protect machine from users
Network and computer support
Cables, networks, servers, data storage
Prototype detectors
A suite of x-ray detectors for experiments
Instrumentation for first Atomic Physics experiments:
Beamline controls
Synchronized laser system
AP vacuum chambers, optics, sample handling, etc.
Installation and Commissioning:
Integration with rest of LCLS and with AP Station

10. X-Ray Detector Project
1st. Meeting of the LCLS Detector Advisory Committee (2/28-3/1/05):
Members:
L. Strueder (MPI Extraterrestrische Physik, Garching)
E. Eikenberry (Paul-Scherrer-Institut, SLS)
Y. Amemiya (Univ. Tokyo)
G. Derbyshire (Rutherford Appleton Lab.)
E. Heijne (CERN)
A. Walenta (Univ. Siegen)
Recommendations:
Proceed with 2 D Detector program at Cornell
Start a streak camera project with LBL

11. Consolidation of XES instrumentation effort
Old Plan:
XES to build a generic set of instrument components
Recently: Science User Meeting (Oct. 04)
Most Recently: - Proposal of PIXEL Project
(Photon Instrumentation for X-Ray Experiments at LCLS)
- A separately funded instrumentation project
(outside LCLS construction)
New Plan:
XES builds one instrument for soft x-ray Atomic Physics studies

12. Rework of XES Schedule
LCLS Endstation Systems will focus on one station: Soft X-ray Atomic Physics (AMO)
XES will still provide global infrastructure for experimenters: Network, PPS, MPS
Other WBS items will be reprogrammed for AMO station: Controls, vacuum, laser system

13. Near Experimental Hall

16. Impacts on XES Planning,
Cost and Schedule
Reworking schedule to focus on AMO station
XES budget stays the same
Schedule only affected in FY06
Hire Atomic Physicist as soon as possible
Coordinate with AMOP working group and PIXEL

17. XES Status Reworking schedule to focus on AMO station
Preparing to add personnel
(Atomic and Detector Physicist)
Starting the 2D X-Ray Detector Development Program
MOU is in signing stage

18. Challenges Build-up of budget and staff in FY05-FY07
Delays in other LCLS areas (conv. construction) would impact schedule
Exchange rate fluctuations for foreign procurements
Few vendors (x-ray optics)

19. Plan for FY05 Hire Atomic Scientist and Detector Physicist
Add Controls Engineer next
Start detailed design of AMO and detectors
Begin R&D on 2-D X-ray detector project
No long-lead procurement

20. Summary
The Endstation Systems will provide the infrastructure between the LCLS source and its users
XES focuses on providing a complete station for AMO
XES is starting to staff up, continue to hire in FY-06
Majority of work during FY-07and FY-08
Start with 2D Detector program now
Prepare to incorporate latest improvements
FH layout and FEE deflection mirror
Coordinating with CF, XTOD and PIXEL project
No long-lead procurements
Risks exists for 2D Detector, but not a high-risk area for LCLS
Coordinating with SLAC safety personnel regarding user safety
