Follow-up Re: Follow-up Re: noise level of arc7 and arc8 vertical correctors

Noted similar ~265 Hz noise on 3C12 labjack. Found similar noise on the labjack in 1A (IPM1A04) which is very broadband (extends past 500 Hz at times) and is very intermittant. Could be the same source Jerone was investigating yesterday. Ops is looking at SEE bpms around the racetrack and Yves looks to have found an intermittant corrector in his logbook entry. Correctors have waveforms and need to find out how they are sampled etc.

Daniel and I were looking at the noise level of the ARC7 and ARC8 vertical correctors after it was noted that we have an intermittent vertical noise oscillation (265 Hz or so) starting around ARC7 . See Attached ELOG .

Interminent noise spikes are clearly seen on the plot. The last large spike is when we cycled this magnet to see if it would help.

Other spikes were during normal running. It is a lock corrector that is kept off loop. Whether this warrants a trim card swap will have to be determined by experts.

IDX at AS01A saturates since July 28

1 day 8 hours ago
Log Number: 4534307Logbook(s): Body: 

The IDX detector at AS01A started to read high dose rates since 07/28 early morning, after switching to the 5th pass. The readings saturate, likely the dose rates are above 10 kR/h there. To get into the range, the Integration Time for the I400 at IDXSL27 may be adjusted down.
