  1. Personnel Protection System Status Patrick Bong SLAC Personnel Protection Systems Group

  2. Schedule • Engineering • Injector drawings are complete • Downstream engineering is beginning • Installation • In process • Scheduled to be complete by November 10 • Certification • Procedure due October 30 • In process • Using a standard template • Scheduled for December 18 • Turn On • Jan 2 - VVSs on for PEP • Jan 15 - start L0A and L0B RF processing

  3. Engineering • Injector Final Design Review • External reviewers • Minor changes were incorporated into the design • Radiation Safety Committee • Approval to proceed with PLC hardware • Approval came later than anticipated, but well within schedule parameters • Requested to see the certification procedure • BTH, Undulator, NEH, FEH • Cableplant design has just started • Design efforts will stop when certification begins in November and start again in January 2007 • Planning on using hardware and PLC software that is similar to Injector design to reduce engineering effort

  4. Procurement • Injector hardware is on site • Beam Shut Off Ion Chambers (BSOIC) • BSOICs are extremely long lead items • Five to Six month lead time from Apantec • Injector BSOICs are arriving too late to use • Plan B is to use SLAC Classic BSOICs • Downstream hardware count must be determined soon • Purchase should occur in November • Most hardware is 90-120 day lead • Cable and hardware will be purchased in January and February 2007

  5. Installation • Injector installation has fallen behind schedule • Racks arrived late • Moving an electrical disconnect held up work • Installation is starting to catch up with schedule • The modularity of the PLC hardware greatly simplified wiring • We expect to make our November 10 schedule • Two chassis are in fabrication due November 6 • Plan B • There are five weeks between November 10 and December 18 when a technician could complete the system

  6. PPS Rack with Operational LSS

  7. Project Status • Personnel • The PPS group added two engineers a designer and a technician • A requisition for another engineer has been posted • Design • Conventional Facilities • Drawings were checked and changes made to accommodate the PPS • BTH, Undulator, Dump, FEE • We have had several preliminary design talks and engineering efforts are beginning • NEH and FEH • The PPS specification in being written based on the LUSI experimental hutch layout

  8. Summary • RSC Approval for PLC based PPS • This is the first use of PLCs in the PPS at SLAC • This is the end of a five year development program targeted at using PLCs in the PPS • Laser Safety System • Laser Bay is already running using PLCs • Injector housing LSS will be completed with PPS • PPS appears to be on schedule • No major worries
