Beam Noise
- Use FastSEE BPM Mode to diagnose intensity and position from injector BPM's with 4 microsecond sampling
- To start : Accel Menubar => EDM => BPM => New FastSEE Control
- MAC or Channel Access is required
- Choose a BPM mode and BPM by selecting corresponding ioc e.g. iocse11
BPMSEE mode Non-invasive BPM spikes update correctly Less samples limit to lower frequency Make sure FastSee Light is ON
FastSEE mode Invasive BPM spikes update erratically More samples for higher frequency ~60kHz
