Updates and status on the MPS commissioning checklists¶

Speakers: Cedric Hernalsteens (CERN), Dr Marek Gasior (CERN), Yann Dutheil (CERN)

a) Update to the LBDS MPS commissioning procedure and checklist¶

Speaker: Yann Dutheil (CERN)

Procedure 896392 for MPS LBDS checks updated to account for the new LBDS test mode. First version reviewed by email with MPP and pending formal review & release procedure

1.1 REMOTE TEST MODE

Since YETS23/24 the LBDS is equipped with a remote test mode allowing to provide an energy signal to the system without local intervention. The changes and validation steps were agreed in [10].

#	Action	Description and criteria	When
1	Ensure the armed LBDS prevents enabling the test mode	With LBDS armed, try to enable the test mode. Ensure this is not possible. Repeat for B1 and B2.	S
2	Ensure the test mode enabled prevents arming the LBDS	With test mode enabled try to arm the LBDS. Ensure this is not possible. Repeat for B1 and B2.	S
3	Ensure the test mode enabling requires OP authorisation	Try to enable the test mode without OP authorisation (given on device LBDS.UA63/7.TESTSEQ.CTRL.B1/2 by lhcop). Ensure this is not possible. Repeat for B1 and B2.	S

b) Update to the BCCM commissioning procedure and checklist¶

Speaker: Dr Marek Gasior (CERN)
