I suddenly noticed that xscaler cannot read BCM information from the helicity gated scaler. (I attached the helicity gated BCM information). The signal in the ungated scaler is still fine so it means that the BCM information reached RHRS but when it was separated to 2 copies, the one goes to helicity gated scaler is lost. I talked with Pengjia, we could not understand the reason yet.
I checked several days' data. All of them do not have BCM information in helicity gated scaler on RHRS. The helicity gated BCM information in HAPPEX DAQ is still fine. Perhaps we could get BCM information from HAPPEX DAQ.
