Safety Systems Development and Review
Process
LCLS Engineering Specification Document (ESD)
is developed in consultation with System
Engineers, RP, and LCLS Management
System Engineers design system
LCLS Project Reviews (SCR, PDR, FDR) are
conducted
RSO/Radiation Safety Committee approval is also
required
System is built by System Engineers and Techs

PPS Status for Jan 2007 Injector
Commissioning and Downstream Development
LCLS Injector PPS Reviews are Complete
RSC ‘conditional approval’ obtained:
Produce written response to FDR and RSC
subcommittee comments and findings (done)
RSC would like to review Certification procedure
(scheduled for end of October)
Hardware drawings, wiring diagrams are complete;
installation in progress
Begin detailed design and review of downstream
systems in Fall 2006 (BTH, NEH)

BCS Definition and Project 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 = desire targeted shut-offs if plausible

BCS System Scope
Original ‘Mode-switching’ BCS proposal has
been sidelined for now
Propose an ‘Interim BCS’ where
conservatively “All BCS faults shut-off all
Guns.”
Mode-switching requirements are now better
understood – move forward with second
proposal for 2007 downtime implementation

BCS Device Scope
2 LION pairs in Injector Region, plus 2 flow switches
Redundant LIONs will be run the entire length of the Beam
Transport Hall (above ground beamline)
Numerous BTM shield walls, plus IC pairs, in BTH
At least two BCS power-limited devices in BTH = 4 ICs
Electron Dump BCS Implementation…
X-Ray system BCS should be 100% passive (no active
components)

BCS Status for Jan 2007 Injector
Commissioning and Downstream Development
Interim design PDR and FDR are complete (Sept
8th and Oct 6th)
Follow-up review of ‘SBI’ implementation needed
New LCLS BCS device compliment for Injectorthrough-TD11 operation is approved by the RSC
(Sept 28th)
RSC Review of Interim BCS system design is
scheduled for Oct 17th
New BCS device compliment for downstream
systems is currently being specified – much is
dependent on LCLS ‘ray traces’

Summary
PPS:
Injector Vault will be ready for Jan 2007 operation
Downstream system development looks to proceed on
schedule
BCS:
Interim BCS design looks to be on track for Jan 2007
operation
New Mode-switching proposal ready for RSO
examination in early 2007
Detailed analysis of downstream system BCS device
requirements is beginning
