John Arthur Photon Systems April 16, LCLS Photon Systems Status Technical status and accomplishments Response to FY2007 continuing resolution LCLS/LUSI coordination John Arthur LCLS Photon Systems Manager

John Arthur Photon Systems April 16, Recommendations from Oct 2006 Put effort into design of critical x-ray optics components (mirrors and thin crystals) Make LCLS Photon Systems and LUSI work together to optimize designs and commissioning plans Putting both recommendations into practice

John Arthur Photon Systems April 16, XTOD Status Still in advanced design phase Nearly all components at least through conceptual review Staying on schedule About to start major procurements Hardware installation can start LLNL team is working well with SLAC

John Arthur Photon Systems April 16, XTOD design for attenuators and x-ray intensity monitors 4.5 meter long, gas attenuator high pressure N 2 section Embedded (Be) solid attenuators Upstream embedded gas detector Downstream embedded gas detector

John Arthur Photon Systems April 16, LLNL Zygo 20× images of Si test substrates by two vendors 0.37 mm vendor 2, loc. 1vendor 1, loc mm LLNL full-aperture interferometry images of Si test substrates by two vendors Vendor 1 Vendor 2 XTOD working with x-ray mirror vendors

John Arthur Photon Systems April 16, Effects of 2007 CR on XTOD Procurements and some design effort were delayed New plan was developed Commissioning optics in FEE ready for first light Beam transport to NEH ready by late FY2008 All work on Tunnel and FEH delayed until FY2009 All work finished by early FY2010

John Arthur Photon Systems April 16, XES Status In design phase AMO instrument design going well 2-d detector development going well Controls area was behind, catching up Working with Radiation Physics on PPS items Ready for installation starting 11-07

John Arthur Photon Systems April 16, Concept for AMO Instrument Focusing optics Experimental chamber Diagnostics chamber

John Arthur Photon Systems April 16, X-ray shutter and mirror layout From the LCLS operating modes Physics Requirements Doc

John Arthur Photon Systems April 16, Effects of 2007 CR on XES Some design effort was delayed New plan was developed Safety and controls work in NEH ready late FY2008 First-stage AMO instrument ready late FY2008 Work in FEH delayed until FY2009 Some AMO instrumentation delayed until FY2009 All work finished by early FY2010

John Arthur Photon Systems April 16, LUSI-LCLS Integration Working Group Define the interface between LCLS and LUSI Resolve issues overlapping this interface Formalize with Interface Control Documents Find common solutions to common problems Experimental instrumentation, diagnostics Standardization where appropriate The Working Group was created by Keith Hodgson and John Galayda to:

John Arthur Photon Systems April 16, Jerry Hastings (LUSI) John Arthur (LCLS) Yiping Feng (LUSI instrument scientist, controls) David Fritz (LUSI instrument scientist, diagnostics) Stefan Moeller (LCLS Endstation Systems Manager) Hal Tompkins (LCLS x-ray installation, commissioning) Other LCLS/LUSI staff as needed Co-chairs Working Group Members

John Arthur Photon Systems April 16, Issues before the Working Group Experimental data flow and interface standards Vacuum hardware and controls standards Conventional facilities/hutches Installation/commissioning

John Arthur Photon Systems April 16, Summary XTOD and XES are still in design phase, though XTOD is moving into procurement and XES will follow soon FY2007 continuing resolution forced some delays, extension of project Technical issues are being resolved with no big problems Should be ready for installation starting FEE, NEH ready in FY2009, FEH ready in FY2010 Coordination with LUSI is going well, has been formalized
