    • ctalab machine
    • Smart UPS
      • # host nevis-ctalab-ups
        nevis-ctalab-ups.nevis.columbia.edu has address 10.44.1.204

      • NOT WORKING CURRENTLY
  • Switched capacitors on test board to power Hamamatsu SiPM (Nancy)
    • Did this to accommodate higher bias voltage needed
    • C1, C3, C4: replace with 100nF, 100V (1206 package)
    • C5, C6, C7: replace with 2.2uF, 100V (1206 package)

  • Tried to find the network card for the UPS
    • Not located upstairs in the supply room as was initially thought
    • Found one that looked like it could be it in Bill's office, but not sure how it could've gotten there with Bill absent
  • Programmed the Aim TTi EL302P -USB PSU
    • added as a class of the dcps python package, new class called 'AimTTiEL302P"
    • can find the code at /home/ctalab/anaconda3/envs/cta/lib/python3.8/site-packages/dcps/AimTTiEL302P.py
      • So far implemented commands to do:
        • Write voltage
        • Write current
        • Read voltage
        • Read current
        • Measure voltage
        • Measure current
        • Turning output on/off
        • Checking if output is on
      • Start-up code is:
      • and then use the `aim` object to do all the commands
    • Still need to implement commands for
      • switching between local/remote (this isn't an option for the model we have)
