keyword=G2p Status Update
Beam can not read the main beam dump. Experts had a long discussion after
the MCC meeting and came out with a list of tasks to find out the cause
of the problem.
We have ramped up our target magnet to 2.5T and MCC will cycle the Harp
and check the beam location with Harps first. Then a control access will
be requested for experts to go down the hall to check the alignment of
chicane and BPMs, re-measure magnet fields, and redo calculations of
Chicane fields and target field, etc.
Diagonalizing beamline issue is the most crucial task we have today, so
during the control access, we need to minimize the number of people in
the hall and let all necessary experts can go down the hall together to
find out the problem. All other activities that are not related to the
beamline issue, please notify Run Coordinator first if you really need to
go down the hall.
After all works completed in the hall and before the hall is close and
goes into beam permit, please contact Ed since he want to be the last
person in the hall to complete the final check-out.
