  • Record data for P-M analysis

Abort Beams in case of failure

Carry the request a.s.a.p. to the Beam Dump System

Time critical (~10 ms) and must be fail-safe

all safety/time critical signals via fail-safe hardware links

Very Time critical (~10 µs) and must be fail-safe

all safety/time critical signals via fail-safe hardware links

Powering Interlock Classes

  • Managed through Interlock Classes

following the LHC Reference Database

  • Depending of the class the attached

process differs after a quench or a failure:

  • Abort (or not) Powering in the concerning Subsector
  • Request (or not) a Beam Dump

Hardware Commissioning

"PIC test system" for Q4/03 Tests procedures “ similar as ” the String2 one Commissioning dates according HCWG schedule Dedicated Beam Interlock commissioning could be partially done. Two phases:

– 2) Before injecting beams: mandatory test of the whole system with all Interlock clients and the closed Beam Permit Loops.

Strategy discussed into MPWG ⇒ Sketch proposed to HCWG

– 1) Single test for client/BIC interface

Beam Interlock: Powering Interlock: Warm Magnets Interlock:

Procedure & dates must be discussed in the HCWG…
