Target and Trigger timing + ToF calibration readiness - 8th March 2015

The purpose of the run is to:

  • time the target into the ISIS beam
  • time the ToF into the ISIS beam
  • BLOC training
  • Get the system to a state where ToF (and CKOV) Calibration data can be taken

SOC Shifts

N/A

Shifter hours of service:

  • Request 1/2 hour shifter overlap for target frame operation training

Data Requested

  • Reference Run: 6-200 setting w/out DS and PA at 29mm
  • Propose to use a pion+ run for data rate studies

Beamline Configurations

  • N.B. Decay Solenoid will not be available.
  • We expect to be running with 2V beamloss and beam bump active.

Reference Run without Decay Solenoid (or Proton Absorber)

Preparation

  • We will run beam into the hall so need to secure the MICE Hall
  • Target needs to be ready
  • BeamLine elements need to be ready
  • Detectors need to be ready
  • Controls needs to be ready
  • DAQ needs to be ready
  • OnMon and OnRec need to be ready
  • Data Mover needs to be ready

Target activity (to be confirmed by Paul Smith)

  1. Work through the target check list and get the target operational with the target frame raised. – 30 mins
  2. Run target in ISIS at MS/128 for reference - 30 mins
  3. ISIS double Machine Start frequency - 10 mins
  4. Check that the target’s insertion aligns with the correct ISIS spill. The target will be operating at the double dip rate. – 10 mins
  5. Stop operating the target and lower the target frame. Ensure that the target insertion depth is small. (Large BCD) – 10 mins
  6. With the beam bump on steadily increase the insertion depth (reduce BCD) until we obtain the required 4 V beamloss. – 1 to 2 hours depending The aim here is to ascertain whether we/ISIS observe any scraping of the ISIS beam during insertion or on the next injection cycle. If there is any evidence of beam scraping then this needs to be mitigated by either altering the target’s parameters or by suitable adjustment of the beam bump. This step will require close cooperation with the ISIS expert. The target parameters that could be altered are the timing of the target’s insertion and possibly its operating voltage.
  7. Once we have a stable configuration for running at the double rate then we can run for twenty minutes to half an hour to obtain some operational data. – 30 mins

Estimated Time ~2.5 -3.5 hours for Target related activity

DAQ testing (to be confirmed by Yordan Karadzhov)

ToF activity (to be confirmed by Yordan Karadzhov)

BLOC training at shift handover (to be confirmed by Henry Nebrensky)

Finish

  • Shutdown target and re-open Hall for Monday
