BGO setup

• It is assumed that you are in the U19:[bgo.daq1] or equivalent directyory.
• SET DEF [.bgo_cal]
• CHANGE_SETUP: Change the default data file to a specified data file. This allows various utilities tp know what the current save file is.
• Change electronics so the BGO detectors can trigger events ( i.e., simulate the RF)
• put in 88-Y source
• ACQ (in the ROUTER/DAPHE window)[acq is actually acq/msu]
• DEHEX1 or DEHEX2: Display first or last 25 BGO energy spectra.
• wait for enough statistics
• type 'end' in the FE window so the MSU data acquisition is not running when you do the calibration. (we cannot get to the fera pedestals when the acquisition is running)
• @AUTO_CAL. Input file e.g. "y88wide_nodisplay.input". The command file fits the two peaks and finds the energy calibration for each BGO element. The procedure lists the results on the screen and in a data file (GAUFIT.OUT). The command file will ask whether you want to use the HV_RESET and FERA_RESSET programs from inside the command file (you normally do!). If you say yes, you should not execute the next two entries...
• HV_RESET. Set the voltages for energy lignup based on the output file D2.DHV from the previous step. The extension DHV means a relative change file and an extension of HV means absolute voltage setting.
• FERA_RESET. Set the pedestal in the FERA. Input file: e.g. D.DEPED (D.EPED, and for time: D.DTPED,D.TPED) following the same rule as above for relative and absolute settings.
• BGO_SETUP. To save all "numbers" associated with the Camac crate including the HV settings and and FERA settings that were adjusted. First specify the old file name, then type SAVE.
