RunPlan20151124¶

Expert run. Aim is to shakedown systems for December run & check through tof calibrations.

Daily schedule¶

November	24
estimated time	8am - 4pm (8pm)
MOM	E. Overton
Shifter	S. Boyd
Shifter	P. Kyberd
BLOC	H. Nebrensky
SOC	D. Rajaram
Aim	Test Run
Beam?	Yes
Additional Personnel	Experts

Plan & Personell:¶

• 8.30am:
  Search Hall (MOM + Shifter1)
  Start setting up beamline (BLOC).

• 9.00 am:
  Hall Searched.
  Setup for pion reference beam.
  Start DAQ when ready
  Check that run control is working with cdb (and cdb is being written)

• 10.00am:
  Check the online reconstruction / monitoring plots for good data.
  Check alarm handlers.
  Speak to physics shifter to ensure they are also getting data / it looks OK?

• 11.00am:
  Switch to running TOF calibration beam.

• 11.15am (MOM, BLOC, DC goto unrelated Meeting).

• 12.30:
  Shifter2 arrives fed to help relieve shifter1/experts for lunch.

• 16.00:
  If everything goes well we stop taking data..

Otherwise, we have Shifter2 to help an expert debug problems until 20.00.

I think this is a plan... its a test run, so it will probably get heavily modified on the day.

Data Requested¶

• Poon Reference
• TOF Calibration

Beamline Configurations¶

We expect to be running with 2V beamloss and beam bump active.

Summary of run:¶

We completed the data taking with success, however there are a number of points where we can improve upon for December. These are outlined below:

Controls:

• KL monitor GUI is blank, but voltages can be read using normal SY527 control GUI.
• Alarm Handler documentation (has been updated - thanks Paolo.).

Detectors:

• EMR was cabled for LED running - now switched to beam mode. Does this change need documenting?

Run Control:

• Initially was operated in expert only mode, since cooling channel was recently added. Needs verifying & documenting for Dec running.

Online Monitoring:

• EPICS alarm work (a little too well). Quite a lot of false positives caused by empty spills (from 0 triggers), alarm thresholds need tuning.
• EMR plots are empty.
• Would be helpful to have more unpacking diagnostics:
  • What detector is causing the unpacking errors (from geo id).
  • In the event of 0 triggers, say that it is consistent.

Online Reconstruction:

• Links to documentation should be provided from the webpage.
• Would be nice to have a "help" or descriptions added.
• Run # should be visible on plots.

Physics Shifter:

• Physics devil was run
• bugs were found which need fixing.
• data transfer to the devil needs automating.
