Entry  Mon May 25 20:27:23 2015, Hao Yin, Belle II, system, Caen PS base line measurements,  P1000760.JPGP1000758.JPG

Baseline noise measurements wo injection.

measure noise in both HV and LV.

wings of APV25 using cmc with 128 strip are visible wo injection. (folder CAEN_PS, run name Noise_xxx.dat).

CMC measurements wo injection:
* LV 300kHz, 1MHz + harmonics
* HV also noisy, few peak showed a induction of about 1 mA. the injected noise goese through p-side HV and returns at n-side HV - and vise versa-.

@ caen HV Ctrl (software)
always shows a current with about 0.5 mA with LV and HV switched off....

(noise wings at fw n side decreased !!!)

Measuring noise emitted by our system.
