  1. Report on Dry Run Jean-Sebastien Graulich, Geneva • Checking Equipments • Trigger upgrade • Online Monitoring • Data quality plots • Summary Jean-Sebastien Graulich

  2. Checking equipments • Know remaining problems • TOF and KL High Voltage Main frame broken • Sent to manufacturer for repair • Weborrowed 2 SY127 HV modules fromLab 7 to power 4 slabs of TOF0 • 3 VME power supplies broken • Sent to cern for repair • Anything else ? • All DAQ/Trigger crates and equipments tested ! • In particular all home made shapers • No sign of change since last summer Jean-Sebastien Graulich

  3. Trigger Upgrade • Long awaited • Delayed for the sake of calibration • Now implemented and tested • Work still in progress • Trigger time tag reset at the beginning of the spill • Allow for measuring the spill profile easily Jean-Sebastien Graulich

  4. Online Monitoring • Didn’t work online • Conflicting compiler miceonrec02a/miceraid2a • Need to share some DATE libraries and ROOT • Following Plots obtained by running offline from files on miceraid2a • Not a Software bug but a link issue • Online reconstruction • Not tested • No expert available Jean-Sebastien Graulich

  5. Monitoring DAQ • All equipments receive the same number of DAQ and particle triggers Jean-Sebastien Graulich

  6. Scalers • Looks all OK • RecordingP.Trg, P.Trg.Req, GVA, TOF0, Lum.Mon and 1MHz Clock • Particle Trigger given by GVA Jean-Sebastien Graulich

  7. Scalers • Looks all OK • RecordingP.Trg, P.Trg.Req, GVA, TOF0, Lum.Mon and 1MHz Clock • Particle Trigger given by GVA (71 requests in 1.5 ms Spill) Jean-Sebastien Graulich

  8. TOF0 • All 4 slabs OK • BothTDCs and ADCs Jean-Sebastien Graulich

  9. Time of Flight • Between GVA and TOF0 • Lowresolution • Enough to separate pion-muons from protons Jean-Sebastien Graulich

  10. KL Tag counters • Only the central slabpowered (2 pmts) • Looks normal (both TDC and FADC) Jean-Sebastien Graulich

  11. Summary • The DAQ isoperational • The trigger system has been updated and tested • Data looks good • The beamlinebehaveswell, includingLumMon ------ Lookingat the badside • Online Monitoring broken • Computingproblem (not even software) • Working on it ! • Online reconstruction not tested • BPM not operational • Craig investigates Jean-Sebastien Graulich
