Bargain SDD module McMaster bought on eBay. Can I get it working without too much effort?

Can get a complete unit + PS for $1500-2500

Thermo power supplies

Some of these on eBay. Are they related?

DA-15, but looks to be the standard preamplifier found on other LN2 detectors. Is this all these detectors need? What about the A/B/C/D tuning seen on the maximusenergy power supply?

Inventory:

  • VORTEX ELECTRONICS SII controller + matching detector. Detector might have TEC issue / doesn't go down to temperature?
  • Spare detector (broken window, disassembled)
  • SEM detector in the mail

Open spare detector up and take some pictures. Wire bonding / complex structure

Mystery component is probably ion pump. Its only used at the factory and has external magnet + electronics to drive it not included in the final unit

2022-10-05

Goal: use breakout board to document DA15 pinout a bit
Use software to test first: Prospect 0.1.16 w/ Saturn processor. Tweak settings and can get noise but no real signal

Controller: SII NanoTechnology USA Inc, VORTEX ELECTRONICS


Detector this was paired with:

  • A 0V
  • B -0.60V
    • But test point actually read -0.476 => corrected
  • C -1.40V
  • D -1.60V
    • Turning pot doesn't affect cal voltage
    • But voltage is correct so leave alone?
  • SDD Thickness 1000 um
    • Affects HV?

Big unit triage:

  • Ion pump loose => was causing the rattling
  • Order new NiMH cells to rebuild battery pack
    • Original: 5P2S w/ NiCd (6V)
  • Window fell off => needs reglue


Pots are just voltage dividers:

  • CW => less negative (decrease magnitude / increase voltage)
  • CCW => more negative (increase magnitude / decrease voltage)
  • 1 => 100x
  • A => 7
  • B => 8
  • C => 14
  • D => 15


Pot D is responding...wasn't it not last time? Looks unstable though. Might need some repair

2022-12-10

Got second controller

  • MMVI-DPP2
  • S/N SNTUS-184-1325
  • Has "SYNC" and "GATE" connectors, removed PARALLEL connector

Initial state of

  • A: 0.00 V
  • B: -0.89 V
  • C: -1.66 V
  • D: -2.10 V
