MSL type BB18 serial # 2977-20 bias +100V I_L +12.0uA T=23 deg C (biased by nnaida # 3 & 5 ) DSSSD - AIDA adaptor PCB cabling 4 off LH Coupler (Kapton PCB, 5cm), 2x 34-way Samtec ribbon cable (62cm p+n, 53cm n+n), RH coupler(Kapton PCB, 10cm) + 3M 1245 1.4mil copper foil screen ribbon cables (i.e. not RH & LH couplers) + drain wires -> gold-plated Lemo-00 test input connectors to FEE64s in 4x FEE module crates Snout drain wire to FEE module Cu block nnaida 3 & 8 AIDA adaptor PCB rev C nnaida 5 & 9 AIDA adaptor PCB rev C (LK1 fitted) ground links LK3 & LK7 fitted to nnaida3, 5, 8, & 9 AIDA adaptor PCBs *** Note added 11.58 sat 30 Apr 2016 Detector bias cable to nnaida3 & 5 adaptor PCBs *but* LK1 fitted to nnaida9 *not* nnaida5. This has been set this way since start of current series of tests Wed 27 April. Connecting via a different adaptor PCB to that connected to the CAEN N1419 bias supply causes significant noise issues presumably due to high resistance path via 2x adaptor PCB to DSSSD cables and the DSSSD bias bus line on the DSSSD. Heavy duty copper cable connects copper front end frames of FEE modules Nitto 5011N conductive gasket between FEE module and front end frames Standard ASIC settings nnaida 3 & 8 - negative input nnaida 5 & 9 - positive input Pulser BNC PB-4 Fall time 1.0ms Rate c.100Hz Delay min Amplitude 50,000 Polarity - Pulse top Tail Atten 10x + polarity via EG&G Ortec 433A Sum & Invert Amplifier Pulser peak widths broad, structured, non gaussian c. 200ch FWHM attachments 1-4 ASIC # 1 waveforms for each acqserver with all acqservers connected to same PSU attachments 5-6 for comparison, from yesterday, with acqservers from two different PSUs - note absence of HF noise in attachments 1-4 cf. attachments 5-6.
