  1. MOM report – part II Jean-Sebastien Graulich as MOM (7.7.2008 - )

  2. Shifts • Two shifts have been organised • Parasitic running is well established • Documentation for Target and Magnets is good enough for a beginner to start with • Results will be presented today • Main effort towards having the Beam Stop removed • Problem with radiation safety • Agreement has been found but it’s a one shot event • We have 1 week-end and only 1 • Starting tomorrow 18.07 at 14:00 until Sunday 20.7 at 24:00 • We need shifters ! • Note that the problem of removing the beam stop will be solved when the removable beam stop is installed • Due for the end of the shut down • Next MOM will have to make sure it happens

  3. Plan for Next Shift • Mainly • Beam line tuning • KL debugging • TOF debugging • We plan to do a current scan of each Q4-Q7 to observe the one dimension focal distance using TOF and KL profile plots • Fairly simple experimental method • Fairly easy to compare with calculation/simulation • It requires changing the polarity of Q7 and Q9 because KL can only give Vertical profiles • Hardware cable swap • This has been done • Back to normal polarity on Monday

  4. TOF0 • TOF 0 has been cabled and tested with scope • DAQ is ready (since 15 mins ago) • Online monitoring ready BUT • NEED online reconstruction: • Profile plots ! Etc… • Need shifters to acquire data with the beam…

  5. Beam Line Monitors • Dan Kaplan has spent a lot of effort when he was main shifter (together with myself) • We have indentify a serious noise problem • Pick up somewhere • Still present when HV is off • Mike Utes will come and have a look, hopefully fix the problem • Dan has suggested to add some logic and require a coincidence of the two planes to validate a hit. • Certainly needed if the pickup noise can not be suppressed • Not sure who will implement this • Nevertheless BM have been used in one of the shift • Kevin will analyse data • First conclusion: X-view is Vertical profile ! (at least in the small counter) • Again, I am note sure who can correct the software GUI

  6. DAQ • A lot of progress on Particle and DAQ trigger systems • Cabling has been improved. All signals labeled • Ultimate test starts tomorrow • If we find shifters..

  7. Incidents • Problem with the Fridge Compressor • Covered in Andy’s talk • Now OK. • Perfectly managed by Mike Courthold • Communication problem with Q4 • Prevented us from using Q4-Q6 in the previous shifts • Now OK • Many thanks to S. Grifiths and his team, including P. Owens

  8. Summary • We’ll have first beam in the hall this week-end • TOF0 is installed and operational • Fermilab Beam Profile Monitors are under investigation • have been proved operational (even though the rate is low) • DAQ is ready to include both and KL • Did I say that we need shifters for the week-end?
