HAMAMATSU R9420 -20 Photomultiplier Tube 1-1/2" (38mm) PMT Spectroscopy w/VD KIT

Description

New 1-1/2" Hamamatsu R9420 Photomultiplier Tube. Great for building scintillation detectors, gamma spectroscopy quality detectors, Gamma Camera replacement, etc. The circuit board on the -20 tube was designed for GE/Gamma Camera use, however it is easily modified for more common applications.
I include a complete wiring KIT and illustrated instructions for modifying the existing circuit board
, The KIT includes a 130 MegOhm Voltage Divider by default, however if you would like a different value, just ask prior to checkout and payment.
The Hamamatsu R9420 PMT normally retails for hundreds of dollars, and very difficult to find new at this price. Get these now for a fraction of the new retail price. Please inquire about bulk quantity of this nice PMT.
Included with this listing is one PMT, VD Wiring KIT, Datasheet & Modification Instructions.
Please check my other listings for this nice PMT available with a voltage divider wiring kit, or with an already modified voltage divider.
