I posted a detailed entry during the night about the evolution of the annular detector but it was deleted somehow...
Signals on 3-4 segments were entirely lost between run 139 and 140. It creates a lot of holes on the impact matrix.
An increase of leakage current from 0.2 to 1.4uA occurred at about the same moment:
*Wed Jul 24 21:44:44 2019 --> 0.2 uA
*Thu Jul 25 06:53:15 2019 --> 0.6 uA
*Thu Jul 25 13:23:48 2019 --> 1.4 uA
*Thu Jul 25 22:25:35 2019 --> 1.3 uA
*Fri Jul 26 07:26:23 2019 --> 1.9 uA
Screenshots about this issues are in the e768s screenshot folder.
Edit : Adding some related files from the folder, not sure if the good ones (Sylvain) |
