To investigate the source of IXV glitch noise correlated to the room temperature (https://klog.icrr.u-tokyo.ac.jp/osl/?r=17912), we installed 4 rolled cables to
- ADC1 CH28 : Cable rack (near the seismometer, originally located) [photo1, photo2]
- ADC1 CH29 : Air cooler [photo3,photo4]
- ADC1 CH30 : Cubicle [photo5, photo6]
- ADC1 CH31 : In the IX2 rack [photo7]
Unfortunately, the temporal channels for PEM were removed from the real-time model.
So far we use IOP channels.
The noisy time was just before this work.
