> 10.00 Powered system on and biased. > Bias voltages and leakage currents ok (see att. 1). Ambient temp @23.1oC. > > 14.00 Shunji wanted to do some checks with the LN2 fill. > Seems to perhaps be a problem with unshielded cables to the valve switches. > With control box, outlet valve and cables to all valves behind LN2 tank, AIDA survives LN2 fill. > Parts ordered to facilitate moving of components behind the LN2 tank, away from AIDA. > Will carry out further tests once these have been fitted. > > 17.00 FWHM seem reasonable and similar to Dec 2016. > n-side FEEs see average pulser FWHM of ~70-80ch. nnaida19 noticeably worse @ ~150ch. (att. 2+3) > p-side FEEs worse with average pulser FWHM of ~200ch. nnaida13 worst of these, showing non-Gaussian peaks > with widths @ ~300ch. (att. 4+5) > Will not attempt to solve this now as they must all be disconnected to sort problem with nnaida1.
