e-Beams System Update

1. e-Beams System Update • Linac System • Preparing for downtime installation. • Injector System • Installation has started. • Undulator System • Moving into production. • Controls • System development advancing.

2. Linac Installation Schedule 250 MeV 4.30 GeV 13.6 GeV 6 MeV 135 MeV Linac-X L =0.6 m Linac-0 L =6 m rf gun L0-a,b Linac-1 L 9 m Linac-2 L 330 m Linac-3 L 550 m 25-1a 30-8c 21-3b 24-6d ...existing linac 21-1 b,c,d undulator L =130 m X BC2 L 22 m BC1 L 6 m ‘Wall region’ DL2 L =275 m Linac, 2007 down Injector, 8-11 ’06 down SLAC linac tunnel research yard

3. Linac • Install during August - November 2006 Downtime • Schedule very tight, seems to be on track • Additional designer manpower • Monitoring SLAC shops, using outside shops • Monitoring progress very closely • In case of conflict with Injector, we must finish the installation in the SLAC Linac housing during the down • Engineering effort has been moved in that direction Talks by Eric Bong and Carl Rago

4. Injector Beamline Installation • Drive Laser May 2006 • Laser Launch July 2006 • Gun Region July 2006 • Accel Region June 2006 • Heater Region June 2006 • Wall Region October 2005 • Injection Region Aug-Nov 2006 • Spect Region Aug-Nov 2006 dates slipping • Gun installation November 2006 Following Hot Test in Klystron Lab • Waveguide through wall and up penetration October 2005 • Injector Installation Complete December 2006

5. Injector • Installation has begun • Most components are being/have been fabricated • There are some items still in design (eg. stands, water) • Finish Injector installation for 12/06 commissioning • Injector installation is being pushed into the downtime – resources will be limited. • Looking at alternate resources. Talks by Eric Bong and Carl Rago

6. Injector Installation Sub-floor cable tray and supports

7. Injector • Gun fabrication • Gun to be hot tested by Klystron Dept. prior to installation (8/1 start). Talk by Dave Dowell • Drive Laser development • Fabrication at Thales is proceeding • Good progress on safety system approval. • Installation conflicts Talk by Bill White

8. Undulator Systems • There is fine progress at ANL • First article Undulators received from the two vendors • Work on the SUT, RF BPMs, … is proceeding

9. Undulator Group Assistant Manager • Rodd Pope • Responsible for assembly, integration and installation of the Undulator system at SLAC • Interface with the Argonne LCLS Undulator Group on Undulator components • Working with • Metrology group for Undulator tuning, precision assembly and installation • Controls group for the specification and installation of infrastructure. • Conventional Facilities group ensuring the environmental stability of the tunnel and the MMF

10. Metrology • Preparing for undulator/girder assembly • Mag. Meas. Fac. BO complete • 1st article undulator due at SLAC 7/06 • Test bench for magnetic meas. due 6/06 • By air freight to maintain schedule • CMM for precision alignment due 5/06 • Wire Position Monitoring, Hydrostatic Leveling systems are under development at SLAC • Hardware integrated with Girder design, and the SUT. • Readout integrated with Controls Talk by Zack Wolf

11. New Head of LCLS Controls • Hamid Shoaee • Arrived in January • LANCE Controls Group Leader • Recent experience with SNS Linac control system and the SNS Controls and Automation group • Previously in the SLAC Controls Dept.

12. PPS/BCS Development and Integration Manager • Mike Saleski • Responsible for PPS and BCS • System design and reviews • Radiation shielding design • Stoppers and stopper systems’ design • Approval by the SLAC citizen committees

13. PPS Global SCR: Nov 18, 2005 Injector (linac+BSY) Informal PDR: Feb ’06 Injector (linac+BSY) FDR: April 27th RSC subcommittee: Functional Requirements Review: March 29th RSC subcommittee: Safety Lifecycle Review: April 14th RSC subcommittee: Technical Review: May RSC full committee: June PPS Review Path From Mike Saleski’s talk.

14. Injector Accelerator Readiness Review • Safety Assessment Document (SAD) • LCLS will be integrated into the SLAC Linear Accelerator Facility SAD. • Accelerator Readiness Review (ARR) • LCLS ARR for Injector Commissioning will build on device and system design reviews. • LCLS Commissioning/Operations Working Group • The Working Group’s role is to coordinate the execution of these tasks and assure the plan is met.

15. Strong Support for LCLS from SLAC groups • LLRF and RF hardware • Klystron dept. design and fabrication of critical LLRF hardware, RF gun, X-band klystron, RF diagnostics • Power Conversion • Specifying, purchasing and installing magnet power systems. • Controls and Power Electronics • Cable plant, vacuum systems, BPM electronics. • High level application development. • PPS/BCS development. • Radiation Physics • Shielding analysis for Conventional Facilities • Simulations for Stopper and Beam Dump designs • Metrology • Strong support from the Metrology group for Undulator assembly • Shops and Accelerator Dept. Operations • Successful October downtime coordination and installation. • Recovery of hardware from SLC Arcs and FFTB

16. Diagnostics development • LCLS will employ state-of-the-art diagnostics: RF BPMs, CSR BLM, EO monitors, OTR screens, X-ray diagnostics… • This development is currently being done by LCLS Engineers and Physicists, with help from SLAC experts. • Technical expertise for diagnostics should be held in a dedicated group, within a SLAC/LCLS Controls group, with sufficient resources to form a ‘critical mass’.

17. Looking forward BO dates from Turner Can installation be advanced?
