keyword=PVDIS (magnets ON, P0= 200 MeV)Turned on the Q2 and Dipole of right HRS by setting the momentum as 200 MeV. The NMR would not lock (see figure 2) at this momentum.
Now the HRS DAQ rate is about 33 Hz (see red trace in figure 1) as opposed to 12 Hz with momentum setting of 600 MeV.
All T8 triggers (regular T1 which is S1 & S2) are taken and all others are prescaled away with a prescale-factor of 9999.
Beam was 12 uA.
HV:
S1, S2, Gas-cherenkov -> 2 kV
Preshower, Shower -> 1 kV
