Thermo Electron Smart connector

XLR7 mini?
- No its 7 male pins + 1 HV pin
Manual refers to it as "YP11579050 smart probe harness"
Disassembled more: VIKING … 12

SHP380AB

Connector: calling the connector with 7 male pins and 1 female pins "male" since its predominately male. This is the connector used on sensors (and meter too probably). Female HV pin is pin 1. Looking into the male connector with the female HV socket at the bottom, pin 2 clockwise from it and continues. The center pin is pin 8.

Straight: anode? Higher voltage

Other, usually curved, must be cathode then

Recommend no more than 0.25" from aplha source
WinE600 computer program used to calibrate?
- Sounds like it has automated checkout
Recommends using lacquer to repair punctured window
Strongly warns against using solvents on scintilator
No evidence scintilator is super sensitive to moisure
Has rough schematic w/ pinout

Pin	Label
1	HV COAX
2	BRAID
3	SIGNAL GROUND
4	BRAID
5	MEMORY PROBE
6	TOUCH MEMORY
7	+5V	N/C If N/C, how is the memory powered? Unclear above signals
8	NON-MEMORY PROBE	N/C

Probe comes apart very easily by unscrewing either side of the PMT assembly. PMT markings

TUBE TYPE: PB29B02H-1

PCB is very simple…basically the resistor chain in the schematic plus two capacitors. Mixed 0603 resistors + through hole capacitors

Electrical tape blob…memory? Not terrible, but could be more elegant. Round…Dallas iButton? ⇒ 1wire if so

An iButton!

eBay 1

Seller has 7 of them. Wants 300 each

eBay 2

Seller had two of them. Wanted 140 each. After a bit of back and forth, this is what I purchased 2 @ 120 each. They might have more…have sold 3 so far, listing 2 at a time

One has NAVSEADET sticker. "NAVSEADET stands for Naval Sea Systems Command Detachment". Mine didn't have it when it arrived, so must have been stock photo from earlier auction
