Making Polarization measurements

  1. Start dbedit on adaq1, select "mollerpol_l" database and set in "beam_pol" configuration table in row "code" parameter "adcevents" from 9 to 2: " ... adcevents=2"
  2. Make at least two CODA runs in order to use both coil polarities.
  3. Data analysis:
    • old DAQ: adaq1:~/paw/moller/
      > paw
  paw> exec run run=15625
  paw> exec lg_spectra run=15625
  paw> exec time run=15625
  paw> lcd mag_optim
  paw> exec anpow_set e0=7.37 (E0 - beam energy in GeV)
  paw> exec asym11 anpow=0.7735 gate=0.033 run=15625 (gate=0.033 for 30Hz helicity frequency and gate=0.0008 for 1kHz)
