Today, Gabor and I discussed with Nathan from ORNL about the biasing system used for Ge, 3He, Plastic, and others. Phong is also a bit familiar with the system (edit also Shintaro Go). While there is supposed to be a manual, Gabor and I did not find it. In case of trouble: contact Nathan Brewer Gmail: Brewer.nathant@gmail.com Skype: nathan.t.brewer Log in to high voltage PC: $ ssh -Y pixie16@10.32.6.161 passwd: ************ For HV readout, run firefox in the background $ firefox & You can probably check the history or restore pages, but it should be pointed at 192.168.13.239 It updates automatically every several seconds. Unless the HV monitor is running, it may show nothing... For temperatures: $ cd ~/DAQ_1/kelvin $ ./kelvin-read (there are options to kill all temperatures) For applying existing HVs (BE CAREFUL!) $ cd ~/DAQ_1/hv-mpod $ ./hvmon If you want to change the voltages (up or down) kill this with Ctrl+C To alter bias values or change which ones are on, you can edit the file: $ ~/DAQ_1/include/hvmon.conf Once the file is saved, restart hvmon. We are running the above in a GNU screen session, with firefox on one computer. It has a note taped to it. Please don't use this computer for other purposes unless necessary! Let me note that the PC we log in through has essentially no .screenrc file so you can barely understand you are actually using screen. If you are not very familiar with screen, better not to touch it. I will put a better .screenrc later (but I also don't want to change the setup now). 28 Mar 2017 15:47:31 Ge voltage application LN2 filling was done yesterday before lunch D is the beam left side Ge MPOD name U300 D4K U301 D4R U302 D4G U303 D4B 83.7 K, with 300 V G is the beam right side Ge MPOD name U304 G7K U305 G7R U306 G7G U307 G7B 79.6 K with 250 V (except G7R at 300 V) All analog signals are seen in the oscilloscope with reasonable behavior 28 Mar 2017 15:56:03 Ramp up all Ge clovers. D at 3000 V for all G at 2500 V for all (except G7R is 3000) 28 Mar 2017 16:26:39 Biases are all applied (maybe several minutes earlier) D4 temp 83.7 K G7 temp 79.6 K 28 Mar 2017 17:51:09 Now we ramp up 3He and plastics. We keep the Ge on during this time. D4 83.7 K G7 79.6 K Everything looks good!
