Schedule and Present Status
4
BOUNDARY CONDITIONS

• Design constraints
• Classical PS Complex-like infrastructure
• Timing integrated into existing CBCM
• Eradication of CAMAC for equipment interface
• User requirements
• Rejuvenated/new interfaces
• Physics oriented operation
• Strategy
• Use standard modules (SW HW)
• Limit new development integration efforts

TIMING PROPOSAL

• Main features
• PPM machine (Pulse to Pulse Modulated)
• Synchronisation with Lin3 CPS
• Variable cycle length
• 3.6 s or any number of Basic Periods
• New Telegram to pilot Lin 3 LEIR
• Integration into CBCM Standard operation
• Constraints
• No Lin3 gt PSB operation
• Predefined cycle length (no pause button)

INTERFACE TO POWER SUPPLIES (2)

• Industrial configuration
• ONLY for 10 e- cooler HV supplies (optic fiber)
• Status
• Preliminary inventory of CO modules
• Technical issue on G64 crate

OTHER INTERFACES

• To beam diagnostics instrumentation
• Next step
• Review of HW SW modules from Eastern 2003
• To vacuum and baking system
• Status
• Industrial controls based upon PLC interfaces and
  PVSS programs
• Under LHC/VAC responsibility
• Next step
• Integration of Controls Middleware server into
  vacuum server machine for access from Operation
  programs (mainly ALARMS)
• To RF and e-cooling systems

RESOURCES ESTIMATE

• Cost
• Preliminary estimate over 2003 - 2006 kCHF
• 2003
• 2004
• 2005
• 2006
• Manpower
• Preliminary estimate over 2003 2006
• From AB/CO 5 FTE
• From AB/OP (application development) 2 FTE
• WARNING !
• Manpower dedicated to LEIR creates HOLES in other
  CO activities

Cost suppressed

ISSUES AND RISKS

• MAJOR ISSUE TIMING system
• Critical manpower
• Competition with deployment of new timing in SPS
  at start-up 2004
• Team limited to 2 experts
• Risk of delay depends on agreed solution

Proposal NO Lin-3 gt PSB operation
