Hitachi Vortex

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

Power supply

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

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?

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
