At low beam current (~5 nA), check the beam position by looking at the rates on the FTCal. Ideally, if the target and FT are aligned, the rates should be symmetric around the hole. Check DC occupancies. | At low beam current (~5 nA), check the beam position by looking at the rates on the FTCal.

− | ''Data taking'', during the weekend: DAQ configuration '''PROD66''', trigger file '''rgb_v0.trg'''. Do a current scan (5, 10, 20, 40 nA) checking and writing down trigger rates, data rates, and DC occupancies. Be aware that with a deuterium target we may get higher rates than for RGA, at a given current. Pick the maximum current that allows acceptable rates (DC occupancies ~3-4%, trigger rates~10k, data rates | + | ''Data taking'', during the weekend: DAQ configuration '''PROD66''', trigger file '''rgb_v0.trg'''.
