Entry number 129291

Assisted Joe Grames with some commissioning of the helicity corrector magnets in the injector, by running our HAPPEX DAQ in the "Beamline" configuration.

Here's a summary of what went down...
First... put both (Hall A and Hall C) IA cells to 5.

Run     What
------------------------------------------
3040    Baseline
3041    0L01V   Even = 1000  Odd =     0
3042    0L01V   Even =    0  Odd =  1000
3043    0L02H   Even = 1000  Odd =     0
3044    0L02H   Even =    0  Odd =  1000
3045    0L03V   Even = 1000  Odd =     0
3046    0L03V   Even =    0  Odd =  1000
3047    0L03H   Even = 1000  Odd =     0
3048    0L03H   Even =    0  Odd =  1000
   Changed Reported Helicity to "No Delay"
3049    0L01V   Even = 1000  Odd =     0
3050    0L01V   Even =    0  Odd =  1000
   Changed Reported Helicity to "8 cycles"
   Set IT=900, OS=1(0)
3051    Checked BPM signals (Forced gain) and BCM ADC channel (HiGain)
   Set IT=900, OS=13(12)
3052    Current scan (20-38uA... 2 cycles).
3053    Baseline
3054    0L02H   Even = 1000  Odd =     0
3055    0L01V   Even = 1000  Odd =     0

   Set IT=13000, OS=1(0).
   Returned Injector BPMs to Autogain.  BCM ADC to LoGain


HAPPEX DAQ back and ready for production data.
