LCLS Controls and Conventional Facilities Mario Ortega, SLAC LCLS - Controls

Controls Breakout – Conventional Facilities (CF) Overview Where WBS 1.9, 1.2.4.4 & 1.3.4.4 meet Injection & Linac Front-End Rack Complex Linac Sectors 21-30 AC Distribution BTH Additional Support Buildings Rack Specification Cable plant Issues

LCLS Controls and Conventional Facilities Technical considerations for LCLS Controls by CF: CF tasked with providing Enclosure, Power, Water, HVAC, Lighting etc. Preliminary Design begins with Physics and Mechanical input MADD Deck Beamline Schematic Movement from Title I (Prelim Design) to Title II (Detail Design) Input from Controls needed to make the leap Controls equipment in some instances require close proximity to beamline devices. Equipment parameters force rack placement CF cannot determine this independently Rack placement(s) drive Building and Tray design

LCLS Injection- CF Sector 20 In advance stage of design – Clearing design with Citizen Committees prior to being let to bid. Demolition of existing racks and cable underway Racks emptied and devoid of cable. AC power last vestige prior to removal. Controls Rack & Tray design holding firm RF Hut height/ Size restriction forces rack mods More details pending to “flesh out” rack profiling

Sector 20 Gallery Rack Locations -Racks service both Injection and Linac Front End (thru BC1) BPM & Timing Racks Magnet Power Supply Racks RF Racks RF Hut (Temperature Controlled) PPS, Vacuum and Diagnostics Racks

LCLS Linac- Sector 21-30 This area nearly unmolested with the exception of: Instrumenting thru BC1 to Injection racks Instrumenting BC2 in Sector 24 New Control system overlaying old CAMAC installation. New BPM modules likely resident. VME Crate installations to support BPM with 3 crates per Sector (all) Major impact on marginal AC service. Power survey idea forwarded. Problem since ~1985 when SLC followed by PEP added.

LCLS Racks Rack Specification has been drafted. Revision pending to include lower height RF Hut racks 38U (66.5”) vs. Standard 48U (84”). Rack drawings exist (minus short racks) Preliminary review to follow CF work. Final Review to follow that with Spec and drawings to comprise Bid Package. Vendors willing to aggregate rack orders with different deliveries for cost saving purposes even though its likely to be in excess of 12 months between deliveries.

LCLS Cable plant Systems Engineers specify cable to be used both internal and external to racks Long Haul Cable subject to SLAC policy As to type, labeling and rating SLAC looking towards use of LSNH A product limited in domestic manufacture More cost = greater safety (particularly in inhabited tunnel areas) Responsible for the ordering or securing possession of external lab cable material prior to cable install contract.

LCLS- Controls & CF Conclusions CF supplied preliminary rack and power details Working the problem is high priority System designs are in preliminary stages Some labor was drawn off to “Start up” machine Linac (S21-S30) AC power can be “Big Ticket” if service is as marginal as understood. Now working with Javier Sevilla, PE on this matter. Survey of existing AC service for Controls while operating proposed. Advancing Rack Spec to approval and on to bid.
