LCLS Personnel Protection System and Beam Containment System

This overview provides information on the roles of personnel, systems scope, current status, and future plans for design, review, and approval of the LCLS Personnel Protection System (PPS) and Beam Containment System (BCS). It includes updates on the PPS layout, status, and review path, as well as details about the BCS scope, modes, architecture, and review path. The goal is to ensure the readiness of both systems for Fall Commissioning.

  1. LCLSPersonnel Protection System and Beam Containment System E. Michael Saleski PPS and BCS Systems Manager

  2. PPS and BCS Overview • Roles of Personnel • Systems Scope • Present Status • Path forward for design, review, and approval

  3. Personnel Roles

  4. PPS Scope • Mixture of: • New PPS Systems • Existing PPS Systems with minor modifications • Hutch Protection Systems (HPS) • Plan to utilize PLC architecture • New at SLAC, increases review burden

  5. PPS Scope

  6. LCLS Injector Vault PPS Layout

  7. PPS Status for Nov 2006 Injector Commissioning • Injector Software development complete • Hardware drawings, wiring diagrams are complete • LCLS Injector PPS FDR is next week (4-27) • Installation is set to begin in June • Begin detailed design of downstream systems in Summer 2006

  8. 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

  9. BCS Scope • Prevents radiation from ‘escaping’ the shielding enclosure • Direct measurements of radiation or beam loss • Protection of safety-critical collimators and stoppers • Entirely new LCLS BCS needed • New gun = new shut-off mechanisms • Support two simultaneous programs (LCLS & PEP) = new set of shut-off paths • Reduce mutual interference of programs as much as possible = targeted shut-offs

  10. BCS Modes

  11. BCS System Architecture

  12. BCS Status • System Concept Review completed (2-24) • System design and PDR series are progressing towards a June FDR • New LCLS BCS device requirements for Injector-through-BSY operation is determined • New BCS device compliment for downstream systems is currently being specified • BCS Engineering Specifications Document is currently being generated (95% complete for commissioning-relevant content)

  13. BCS Review Path • System Concept Review: Feb 24th • PDR series is underway (April-June) • FDR is on track for June • RSC System Review is needed; not scheduled • RSC Review of BCS device compliment for Injector through BSY operations is needed; not scheduled:

  14. Summary • PPS: • heavy review schedule, but expect readiness for Fall Commissioning • BCS: • Conceptual design of hybrid CID/LCLS BCS is complete, including new shut-off mechanisms • 2-month PDR process is initiated; FDR in July • Expect readiness for Inj-to-BSY operation in November
