<p>16/02/2015</p> <p>1500: AIDA moved into operational position.</p> <p> Water cooling circuit visually checked, fittings, etc for loose fittings/snags/kinks. No problems</p> <p> Julabo FL11006 chiller moved into position with mains transformer, filled and turned on without problem (small leak from rear overflow, due to overfilling).</p> <p> Took roughly 2 ~30L water containers to fill reservoir.</p> <p> Brief leak at connection between back of chiller and yellow hose, bolt tightened and it stopped.</p> <p> Having been turned on and loop filled, reservoir at ~50% full. Pressure ~10 psi.</p> <p> No leaks observed in main coolant loop.</p> <p> When standing downstream of AIDA RH flow gauge blurred due to high rotational speed, LH flow gauge rotating at ~1 rev/s.</p> <p> Two FEE modules closest to centre in each block checked for power cabling, TS distribution and network cables. All ok.</p> <p> MACBs front panel cabling checked, no obvious problems. TS distribution tree in order.</p> <p> Power on for NIM bins and fan tray, network switches and Raspberry Pi. Not yet for the FEE module PSUs.</p> <p> </p> <p> 1 corner of each new USB power supply damaged in transit.</p> <p> Fuses changed from 10A -> 16A in each PSU. Old 10A fuses taped to back of each module.</p> <p> </p> <p>1730: Turned on nnaida1-16. Temperatures stable. All on firmware version 0xa4ed006.</p> <p> Input pulser into all FEE cards. All FEEs bar nnaida5 well-behaving. nnaida12 has several missing channels.</p> <p> Typical pulser peak width for -ve input modules was ~14ch FWHM with shaping time of 1us.</p> <p> Typical pulser peak width for +ve input modules was ~27ch FWHM with shaping time of 1us.</p> <p> Changing shaping time of nnaida10 from 1->2.5us reduced FWHM from 27ch to 23ch.</p> <p> </p> <p>Attachment 1: temperatures & FEE firmware revisions nnaida1-16</p> <p> </p> <p> </p>
