Subject: First time remotely power up HV in RIKEN from Daresbury 

Logged into aidas1 and opened the nnrpi1 relay control window ... powered up the FEE64s.

seperatly connected to ribfdaq and opened a firefox to aidas1:8015.

By the time the firefox had appeared on my desktop the FEE64s had started up.

Ran through the standard startup. Set thresholds to 255 for all 3 sets of comparators. Disabled all discriminators.

Enable histograms.

Started DAQ.

Using ELOG 74 as a guide logged into nnrpi1 and ran two putty sessions ( USB2 and USB3 ).

Based on the instructions in the HV unit manual attached to ELOG75 powered ion all 6 detectors ( current when settled at 100v = 3 to 5uA )

Using spectrum broswer at nnaida6 and ASIC4 to control the slow comparator threshold ..... needed to reach 32 before the pulser became visible.

Using nnaida6:1.3.L found the pulser peak at channel 32136 with a peak width of 67.73 channels.

Then poweroff the HV on all 6 detectors.

Power off the FEE64s.

Logout of all RIKEN machines and consider the best way to take advantage of the situation which allows the system to be operated completely remotely.
