Note: Due to the situation in Ukraine the tubes for this detector are temporarily out of stock.

Neutron Detector

Fully assembled neutron detector with moderator preamplifier and battery. This detector contains a Russian SI19N (He3)  tube and requires a high voltage power supply capable of supplying 1750 volt bias. Only minimal current is required as the tube has very high impedance. The preamplifier is a Schmitt trigger type and outputs a 3.3V square wave pulse for each count.
