16. Jose Chan FAC - BC2/Linac Installation Status & Schedulejqchan@slac.stanford.edu 4/16/07 16 Issues & Concerns Presented 2007 Installation Readiness Review in March Committee’s concerns If the linac installation tasks identified as “low priority” are not implemented then the maximum achievable energy from the Linac will be reduced, this may affect non-LCLS programs. This will also limit or delay the commissioning of systems through BC2 Readiness of hardware needs to be tracked to ensure availability by the downtime. Components like the kicker magnet, whose design is not yet complete, has no fabrication schedule input by MFD, and the ceramic chamber may have a long lead time. Pre-installation readiness and component testing should be a high priority to reduce in-field interferences. Space for BC-2 mock-up and testing could help identify technical issues before devices are installed in the tunnel. Scope definition is vital to a successful installation and the work required for the water system and BSY was not clear. Develop a clear and concise plan for the downtime work. Integrated schedule is required to determine if scope of work can meet the downtime constraints

17. Jose Chan FAC - BC2/Linac Installation Status & Schedulejqchan@slac.stanford.edu 4/16/07 17 Issues & Concerns Engineers and coordinators Some of mechanical engineers are still involved in commissioning of LCLS injector system Depend our commissioning success, if does not go well then is likely more resources brought back into injector L2 De-scoping wire scanners “will impact the commissioning significantly - P. Emma” BC2 design New articulation and support designs Not enough time or space to test completed installation assembly in the lab. Plan to test sub-assembly in building 26. Bend magnets are substantial larger than BC1 bend magnets L3 design Designs for BXKIK and OTR-TCav not completed

18. Jose Chan FAC - BC2/Linac Installation Status & Schedulejqchan@slac.stanford.edu 4/16/07 18 Issues & Concerns 2007 downtime installations 2006 commissioning encountered a few problems with diagnostic components 2007 new components will be verified and signed off by design engineer, control engineer, alignment group and physicist before installation Post installation sign off 2007 downtime 10 weeks vs. 2006 downtime 17 weeks Reconfiguring 13 Linac girders vs 3 in 2006 More waveguides in Linac housing Longer distance from equipment lowered down to installation areas Davis Bacon Linac installations maybe competing with LTU installations Water work less than 2006 installation Hardware and cable installations co-habitat in same area Not much time for control to check out hardware
