- Test with INDIV to investigate B2 dump at start of ramp, beam lost when blowup activated regardless of bunch length target or funny BQM readings, traced back to issues with the phase loop and possible synchro error issue before. - Still BQM reading glitches in the bunch length - B2 tunes FF based on previous ramp with INDIVs in both beams |
