Hamamatsu R6095 photomultiplier tube

I’ve bought this R6095 PMT tube from iRad ebay seller. It cost me about 40$ plus shipping. iRad sells it as just tube or with socket and voltage divider kit. I’ve bought the complete kit.  A link to his auction: iRad

This tube could be used to make a nice scintillation probe coupling it with a 30mm diameter NaI(TI) crystal and feeding 800-900V. Yes… just 900 and you can expect a gain of 10^6. Within the box there is the datasheet of the tube plus an instruction sheet to wire the voltage divider network to the socket.

Tube plus socket and instructions
