POST-MORTEM ANALYSIS (chap. 6.9
& 9.8)
lIn case of a beam dump,
the BLM system should help answering the following questions:
èis the beam dumping clean
or were there unexpected losses around the machine?
èwhat is the cause of the
dump action: beam losses triggering the BLM or internal magnet quench
protection interlocks? Other machine interlocks without prior beam
losses?
lThe signals of all
monitors should be buffered for the last 100 - 1000 turns, such that they can
be read out and analysed after a beam-dump. In addition, the average rates
of all monitors should be easily available for time scales of a few
seconds and 10 minutes before a beam-dump.
