T2 Profile Monitor actuation was tested today from the control room and all is working properly. The position (IN / OUT) also displays correctly.
To my knowledge nobody has looked at this system, so it is a mystery why it suddenly started working. This e-log will be updated if any explanation is found.
Actuation of the M20 beam blocker and T1 Profile Monitor were also tested and are working as expected.
The T2 monolith may now be covered.
Update: A blown fuse in the control racks was replaced yesterday by Dave Cameron, which explains the change. |
