keyword=Re: Cut Changes
After some discussion, we've decided to change the cuts used in Parity Feedback again to:
lobeam 2000
burpcut 1500
cutnames Low_beam Beam_burp Oversample Sequence
extlo 10 10 25 25
exthi 1200 40 25 25
The beam is ramped 10uA/30s. Therefore, a 1200 exthi for Low_beam will give us roughly 40s... sufficient time to recover from a beam trip. This will also provide the possibility of providing charge asymmetry feedback for much less than 12uA (probably down to 5uA).
