09.45 Found CARME electrical power off Reset power switch of distribution box to on Reset fuse of 19" rack extender board One of the SIP power modules may be faulty - others switch on OK 14.00 Checked coolant water flow OK Transferred Netgear 24 port Gbit switch from AIDA (S4) to CARME (YR09) Re-connected FEE64 RJ45 network cables Re-connected nnrpi1 RJ45 network cable Re-connected RJ45 network cable (yellow) to bottom left connector of YR09 patch panel @CRYRING user control rooms Connected RJ45 netwwork cable (yellow) from bottom left connector of patch panel (labelled "1-2->YR10" and "3-4->YR10") to CARME server carme-gsi p4p1 port Retarted HttpdTcl servers on nnrpi1 and carme-gsi. Normal 5x FEE64 power up All system wide checks OK FEE64 temperatures OK - attachment 1 ASIC settings slow comparator 0x64 Pulser running through aida01-05 Detectors not biased -> lot of noise aida01-04 AIDA stats - attachments 3 & 4 aida05 pulser width ~150 channels FWHM, normal settings, shaping time 8us - attachment 4 See attachments 2-4 Tried changing ADC control register to 0xf in local controls tab -> stops waveform producing data -> no effect on pulser width (slight increase to 160 chn) fast comparator blanked off (enable disable mask in discriminator control) -> no effect on pulser width aida05 was ungrounded -> grounded aida05 to the same ground as aida01-04 -> pulser width reduced to 46 chns Set ADC control register back to 0x0 -> waveforms back -> pulser width reduced to 24 chns Changed shaping time from 8ms to 1ms -> pulser width increased to 67 chns -> changed back to 8ms shaping time -> returns to 24 chn width Changed shaping time from 8ms to 2ms -> pulser width increased to 52 chns Changed shaping time from 2ms to 4ms -> pulser width decreased to 33 chns
