keyword=beam energy spread was too high
At the begining of the shift, beam trip frequently. MCC took beam away and did some tuning. It became stable when beam was back. But
Arun Saha noticed that the energy spread was too high (5x10-5). Requested MCC to bring it down (to below 4x10-5). The data taken with
the large energy spread is not good. Will need to be repeated after
the spread comes down.
