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