Beam Noise

Use FastSEE BPM Mode to diagnose intensity and position from injector BPM's
  1. To start : Accel Menubar => EDM => BPM => New FastSEE Control
  2. MAC or Channel Access is required
  3. Choose a BPM by selecting corresponding ioc e.g. iocse11
  4. Sampling rate 4 micro-seconds and frequency of sampling is the display rate
