1. Stefan Moeller Revised XES Scopesmoeller@slac.stanford.edu April 7, 2005 Revised X-Ray Endstation Scope Stefan Moeller

2. Revised XES Scopesmoeller@slac.stanford.edu April 7, 2005 XES Scope The X-Ray Endstation Systems group will create the infrastructure required for experimenters to make best scientific use of the LCLS radiation safely

3. Stefan Moeller Revised XES Scopesmoeller@slac.stanford.edu April 7, 2005 The Endstation Systems will provide: Personnel protection systems (PPS) Protect people from x-rays, lasers, etc. 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 Hardware, software Synchronized laser system fs laser system synchronized to FEL Mechanical/Vacuum AMO - and sample chambers

6. Stefan Moeller Revised XES Scopesmoeller@slac.stanford.edu April 7, 2005 LCLS Endstation systems coordination with the LCLS experimental equipment project (PIXEL) The PIXEL project is a separate project from LCLS construction LCLS-funded items and experimental equipment items must be kept separate PIXEL equips 3 hutches Different project lengths Coordination is important

7. Stefan Moeller Revised XES Scopesmoeller@slac.stanford.edu April 7, 2005 Consequences for LCLS Endstation Systems Revised XES Scope: LCLS X-Ray Endstation Systems will build one station, for soft x-ray atomic physics XES will still provide global infrastructure for experimenters (Network, PPS, MPS) Now: Other WBS items will be reprogrammed for AP (beamline controls, vacuum, lasers) So LCLS resources and schedule within the Endstation systems group are being rearranged so as to provide maximum capability for the LCLS-funded atomic physics station

8. Stefan Moeller Revised XES Scopesmoeller@slac.stanford.edu April 7, 2005 Soft x-ray AMOP experimental station in hutch #1 (NEH) Atomic Physics to explore interaction of FEL beam and matter on a fundamental level Inner shell photo absorption processes Photo-fragmentation analysis Focused and/or pump-probe geometry AMOP Experiment

Philip Bucksbaum (Univ. Michigan) Todd Ditmire (Univ. Texas-Austin) Gerhard Paulus (Texas A&M) Linda Young (ANL) 1st Report: LCLS Atomic Physics Working Group, Argonne National Lab, April 30, 2004 Workshop: Ultrafast Science and LCLS Experiments October 25 - 26, 2004 LCLS Experiment Leaders Meeting, March 30-31, 2005

10. Stefan Moeller Revised XES Scopesmoeller@slac.stanford.edu April 7, 2005 The Near Experimental Hall FEL beam Experimental hutches Shops, setup space AMOP Hutch Soft X-ray

11. Stefan Moeller Revised XES Scopesmoeller@slac.stanford.edu April 7, 2005 AMOP Hutch Layout Optics: monochromator, focusing system Laser system (higher power) Sample System Chambers (sample, diagnostics) UHV system Detectors (particles, e, ions) Diagnostics (x rays, laser)

12. Stefan Moeller Revised XES Scopesmoeller@slac.stanford.edu April 7, 2005 Impacts on XES Planning, Cost and Schedule: As before: XES will provide global infrastructure for experimenters (Network, PPS, MPS) Now: Other WBS items will be reprogrammed for AP (beamline controls, vacuum, lasers) Coordinate with XTOD equipment placement in hutch1 Cost neutral changes Schedule only affected in FY06 Hire Atomic Physicist for XES as soon as possible Coordinate with AMOP working group and PIXEL

13. Stefan Moeller Revised XES Scopesmoeller@slac.stanford.edu April 7, 2005 Plan for FY05 Hire Atomic -, and Detector Physicist as soon as possible Hire Controls Engineer next after Start detailed design of AMOP and Detectors

14. Stefan Moeller Revised XES Scopesmoeller@slac.stanford.edu April 7, 2005 Summary The endstation systems will provide the infrastructure for the interface between the LCLS source and its scientific applications The endstation systems group is coordinating with the instrument development project (PIXEL) and XTOD and is focusing its activity on one AMOP station in one hutch XES will work closely with LCLS AMOP working group Revised scope is being programmed and implemented
