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

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
