Photon Systems Update John Arthur SLAC Photon Systems Manager April 20, 2006 Photon update John Arthur jarthur@slac. stanford. edu
Photon Systems Includes LCLS x-ray and laser groups X-ray Transport, Optics and Diagnostics (XTOD) managed by LLNL (Richard Bionta) X-ray Endstation Systems (XES) managed by SLAC (Stefan Moeller) Laser Systems managed by SLAC (Bill White) April 20, 2006 Photon update John Arthur jarthur@slac. stanford. edu
XTOD Scope Transport the x-ray beam, in vacuum, to all the experimental stations Condition the x-ray beam, with attenuators and apertures Analyze the x-ray beam, with sophisticated diagnostics April 20, 2006 Photon update John Arthur jarthur@slac. stanford. edu
XES Scope The X-Ray Endstation Systems group provides the infrastructure required for experimenters to make best scientific use of the LCLS radiation safely. Includes advanced x-ray detector R&D. April 20, 2006 Photon update John Arthur jarthur@slac. stanford. edu
Laser Group Scope The Laser group coordinates laser design and acquisition throughout the LCLS. Lasers will be used in the electron gun and x-ray experimental areas, and also possibly for accelerator diagnostics and alignment. April 20, 2006 Photon update John Arthur jarthur@slac. stanford. edu
LUSI Project Scope LCLS Ultrafast Science Instruments is a distinct DOE project closely coordinated with LCLS. It will build 4 science instruments which will occupy LCLS x-ray hutches. This will enable work in three of the LCLS Science Thrust Areas: X-ray pump-probe dynamics, Coherent x-ray imaging, and X-ray photon correlation spectroscopy. The project is ramping up, with major funding expected in FY 2007. April 20, 2006 Photon update John Arthur jarthur@slac. stanford. edu
X-Ray Systems Status FY 2006 is a design year XTOD designs are undergoing reviews now XES designs ready for review in a few months FY 2007 is a build year Ready for installation starting August 2007 Ready for first light in Spring 2008 April 20, 2006 Photon update John Arthur jarthur@slac. stanford. edu
Recent Events FAC Oct 2005 Recommendations Coordinate with experiment teams Make x-ray mirror design a priority Don’t cut flipper mirrors or move FEH LCLS actions Coordinating with LUSI Mirror optics design underway Had to cut flipper mirrors and move FEH April 20, 2006 Photon update John Arthur jarthur@slac. stanford. edu
NEH Hutch 1 9. 5 x 10 m Hutch 2 Hutch 3 Flipper Mirrors April 20, 2006 Photon update John Arthur jarthur@slac. stanford. edu
Reduced scope FEH design Entrance tunnel single beamline 46 ft tunnel Hutch 4 Hutch 5 Hutch 6 19 ft tunnel 212 ft April 20, 2006 Photon update John Arthur jarthur@slac. stanford. edu
Other Cuts Some XTOD diagnostics Not needed for commissioning, expect to add as part of operations Some XES generic detectors Expect that LUSI will provide experiment-specific detectors XES support for generic computers for experiments Expect that LUSI will provide experiment-specific computers April 20, 2006 Photon update John Arthur jarthur@slac. stanford. edu
Other Developments for XTOD New Physics Liaison: Peter Stefan Revised work plan incorporating cuts Designs moving through review stage Gas attenuator prototype Slits Beam transport April 20, 2006 Photon update John Arthur jarthur@slac. stanford. edu
Other Developments for XES New hires John Bozek, AMO physicist Niels van Bakel, Detector physicist Revised work plan incorporating cuts 2 d x-ray detector development program on schedule Working closely with upgraded LCLS Controls Group April 20, 2006 Photon update John Arthur jarthur@slac. stanford. edu
LUSI Progress Jerry Hastings is now Project Director Initial hiring taking place Nadine Kurita, Chief Engineer Bill Foyt, Project Manager Working closely with XES and XTOD groups to develop an optimal layout for experiments April 20, 2006 Photon update John Arthur jarthur@slac. stanford. edu
Better Beam-Splitting Plan LCLS and LUSI are working on an updated beam-splitting plan, and a way will be found to implement it This includes not only splitting of the beam to the FEH, but also splitting into a soft x-ray line and hard x-ray line in the NEH Will allow quicker changes between experiments Has become possible as experiment designs are beginning to crystallize April 20, 2006 Photon update John Arthur jarthur@slac. stanford. edu
NEH AMO SXR e soft x-ray lin X-ray pumpprobe hard x-ray line Flipper Mirrors April 20, 2006 Photon update John Arthur jarthur@slac. stanford. edu
FEH XPCS Coherent x-ray imaging April 20, 2006 Photon update High energy density science John Arthur jarthur@slac. stanford. edu
Summary Cuts have been made, but not too drastic Design effort underway LUSI is beginning to help April 20, 2006 Photon update John Arthur jarthur@slac. stanford. edu
