> 14.30 DSSSD stack moved upstream to position DSSSD#3 at centre of EURICA. > > Initial tests of detector bias with DSSSD #1-6 were Ok. Unfortunately we were unable to bias > DSSSD #7 obtaining either open or short circuit depending on which of the two p+n junction > side and n+n ohmic side detector bias bus lines we connected to. > > Demonstrated that short circuit was upstream, of AIDA adaptor PCB by disconnecting Kapton > LH couplers. > > Remove DSSSD stack and replace DSSSD #7. In progress. > > 15.50 Startup AIDA with DSSSDs disconnected > > Temperatures & firmware version - see attachment 1 > AIDA SYNCs - attachment 2 > System wide checks - attachments 3-6 - note persistent nnaida19 ASIC clock and SYNC errors > Statistics nnaida19, 20 - attachments 7-8 > > nnaida19, 20, 27 & 28 hit pattern and waveform spectra - see attachments 9-13 > > Some nnaida19 system wide errors above and noisy ASIC#4 hit channel for nnaida28 - otherwise OK
