keyword=G0 delay on helicity control board changed to 4 cyclesKent noticed that on the helicity control board epics screen, there was a helicity signal with no delay. The signal was labeled "G0 delay," and we believe it was used to pulse their dummy Pockels cell. Since this is potentially a real-time helicity signal going somewhere in the accelerator (right now, we don't know if anything is connected to it), we asked MCC to change it to a 4 cycle delay. So, now this signal is no longer a real-time helicity signal.
