As requested in yesterdays 17.00 meeting, all UNMASKABLE inputs from the PICs for injection into 23 have been disabled, thus the PIC interlocks will only appear on the MASKABLE inputs of the BICs in point 2 and 3. In order to be sure to take them into account please make sure that if you are injecting into 23 the MASK at the BIC level is not active (as currently the case in the BICs of IR2)...

Following the Bernd’s proposal, we came to the following decision:

-          both “maskable” inputs will be enabled on CIB.UA83.L8 and on CIB.SR7.S7.

-          the corresponding “UNmaskable” inputs stay disabled on these BICs.

This choice shall imply a modification in the BLM database (=> ALL monitors on the maskable channel).

As discussed together this morning, here are the preliminary decisions taken about the User systems that will be enabled/disabled for the Beam‐2 injection test:
(Unmaskable channels are in Bold)
‐ 1) inputs enabled on CIB.TZ76.U7
o Vacuum
o PIC (Essential & Auxiliary)
o WIC
o COLL (Mot. & Env. Param.)
o BTV‐b2
Disabled input: none

‐ 2) inputs enabled on CIB.SR7.S7:
o BLM (UNmaskable & maskable) => ???? decision will be taken on mid next week
o FMCM units
Disabled input: none
‐ 3) inputs enabled on CIB.UA83.L8:
o Vacuum (sector valves & Sector‐X valves)
o PIC (Essential & Auxiliary)
o WIC
o COLL (Mot. & Env. Param.)
Disabled input: none

‐ 4) inputs enabled on CIB.UA87.R8:
o Vacuum (sector valves & Sector‐X valves)
o PIC (Essential & Auxiliary)
o MKI8
o LHCb (Detector part)
o LHCb (Movable Dev)
o COLL (Mot. & Env. Param.)
o BTV‐b2
Disabled input: LHCb Magnet

‐ 5) inputs enabled on CIB.CCR.LHC:
o Operator Buttons
o Access system
Disabled input: Programmable Dump

‐ 6) inputs enabled on CIB.SR8.INJ2:
o Operator switch
o Beam2‐Permit from LHC‐ring BIS
o MKI8
o Vacuum
o LHCb (injection inhibit)
o COLL (Mot. & Env. Param.)
o FMCM on MSI
o MSI Power Converter
Disabled inputs: Atlas, Alice, CMS, Totem & LBDS

‐ 7) Concerning the inputs on BICs(*) that were involved in previous Injection test:
o We leave enabled the PIC (Essential & Auxiliary) channels
o We leave enabled the Vacuum channels
o We leave enabled the MKI2 channel ????
o We have to disable the Alice channel
(*): CIB.UA23.L2, CIBUA27.R2, CIB.UJ33.U3 & CIB.SR3.S3

The safe beam flag should be forced (in point 2/3/7/8) to true to test the “maskability” of the interlocks including the BTVs 􀃎 Bruno, Ben.
