FREE SHIPPING USA! This is a small 12mm diameter lithium iodide scintillation crystal. This crystal is from a SAIC neutron detector. It was originally coupled to a small PMT. It responds to Slow neutrons as it is, and with a nice chunk of polyethylene or even plain candle wax, it detects FAST neutrons very well, so it may be of interest to fusor builders. Even though it is designed for neutrons, it still detects gamma rays too, just turn up the detector gain. The only difference is the spike of light with a neutron capture event is far brighter than any normal gamma event. This allows you to discriminate the energy by lowering the detector gain so normal gamma background is negligible. All you need to make your own detector head is a small PMT tube or large area PIN photodiode detector. They fit the R-7400 bare can style PMT tubes exactly, but a bigger PMT will give better resolution. I have the suitable PIN photodiode in another listing with a couple high gain amplifier boards. If you need this, here is your chance. Be sure to see my listing for a 3He neutron detector tube too! This item is pretty hard to find I have lots of lasers and other unique stuff for sale this week.
