Target Operations & Data Taking

See information by Paul Hodgson, Chris Booth, Paul Smith Many congratulations on a very well done job! Thanks to Malcolm for getting everything ready to run! Ran 12 hours Saturday & 16 hours Sunday Used 11,803 target pulses Target operation studies

Searching for ideal timing wrt ISIS cycle Searching for ideal depth into beam Found edge of beam at injection for purposes of understanding what we need to avoid on

the outswing of our target Took data with modified voltages

Beam loss vs Particle Rate study Fix target timing and adjust dip depth Take data at 100 mV, 200 mV, 300 mV, 400 mV, 500 mV beam losses

Pion beam at 333 MeV/c Proton beam at 333 MeV/c Muon beam at 252 MeV/c with Decay Solenoid and w/o

Preliminary:Beam Loss vs Particle Rate Study

first draft, means of distributions judged by eye, no error calcs, etc full analysis is to follow rates of beam loss seem very high because not yet been calibrated to nominals

last time the reduction factor was about 0.4, PH thinks more this time. unsure at present as to what units have for the GVA1 (why are no units for them, again to be sorted out

for full analysis)

Operations

Rehearsal of running good idea Updated documentation very helpful

Still need a few updates Some trips of beamline magnets DAQ having some trouble with new fADCs

Working to sort this out now “invalid” alarms constantly going off on alarm handler extremely

taxing/annoying

Would like TOF1 KL

What is our run plan for Machine Physics given all that was done this weekend??
