keyword=Unstable beam position
MCC lets us know that our beam position has started to become unstable. Indeed, the BPM readings seem to oscillate by ~0.2 - 0.3 mm. The cause is an unstable box supply. Experts have been called in. We decide to continue to take beam, even if the data quality may be affected.
