== <font color=blue>'''B. Run Plan'''</font> (see also [https://userweb.jlab.org/~kuhn/BONuS12/Documents/RunPlan.pdf initial run plan]) ==
General plan: Follow a sequence of 6 Days D2 (240 nA), 2 shifts H2 (240 nA), 1 2-hour run empty (250 nA) and 10M events on 4He (240 nA).
 
  
=== Short term plan  ===
 
# Turn off all the detectors.
 
# Establish the beam on the tagger using 5nA beam and compare the harp scans to the references (blank collimator, beam type photon, FSDs U/M/D/BOM are masked))
 
# if beam is acceptable, call mcc and tell them to take the beam away and prepare for a moller run
 
# call mcc and ask for 4nA beam and take a moller run.
 
# take the beam away and exit the moller configuration.
 
# take another harp scans on 2c21 and 2c24 using 5 nA beam current, if they are good ask mcc to take the beam away and de-gauss the tagger magnet.
 
# prepare for beam to FC:
 
## change beam type to Electron.
 
## All HV are off (including FTOF and RTPC)
 
## Check that 20 mm collimator is in
 
## Call MCC to unmask U/M/D counters but keep BOM masked or get it masked in case it isn't
 
## Put thresholds on U/M/D as 1M/1M/1M and dwell time 50 ms.
 
## Call MCC to put 5-9nA to the FC.
 
## Compare the 2c21, 2c24, 2H01 positions and beam overview screen to the reference below
 
## follow the procedures for the harp scans at 2H01 [https://wiki.jlab.org/clas12-run/images/9/9f/HarpScanManual.pdf] (also do harp scans on 2C24)
 
## Compare the results with the references scans below (be aware to use the correct analysis counter)
 
## if what you get isn't similar to the references or If you are not sure if a tune of the beam is needed, consult beamline expert and/or RC.
 
# EVERYTHING ABOVE IS DONE AND OK. Here are the next steps:
 
## MCC expert calibrate 2H01
 
## Unmask and set all FSD parameters to nominal - call MCC and tell them the the beam is acceptable and set FSD thresholds and dwelltimes to the standard values below
 
## Do a quick position scan on the 2H01 (target) using 10 nA beam current (RC or beamline expert job). This should be done with MCC on speakerphone so they can continuously move the beam in x or y (both directions) until a significant increase (>50%) in BOM count rate is seen. Note the 4 edges and center beam in middle.
 
## Ramp up all HV
 
## Start running on D2 with 200 nA

=== Plan for Monday Morning, Sep 21st ===
 +
# 07:00 : The beam will be taken away for some MCC studies. Gagik, will confirm with MCC that the Hall goes to Controlled Access.
 +
# 07:00 to 8:00: Gagik will call Eugene to ramp down the torus and ramp the solenoid to 1.5T.
 +
# 07:00- 08:00: Gagik can turn off HV on the following detectors ONLY (LTCC, HTCC, DC, RICH, FMT, FTC, FTH)
 +
# 08:00: Gagik leaves the counting house and the BONuS team (Jiwan and Sebastian) will join to do final cosmic tests.
 +
# Before 12:00: the solenoid be totally ramped down. the bonus team will be in contact with Eugene.
 +
# 12:00: The bonus team will turn off HV on ECAL, PCAL, and CND.
 +
# FTOF and CTOF must be left turned ON.
