NEUTRON DETECTOR (With Russian SI19N He3 Tube)

High efficiency slow neutron counter tube, built into a convenient aluminium housing with standard SHV connector. 

At around 1400 V bias neutrons produce a proportionally higher pulse than gamma rays allowing the latter to be discriminated using a lower limit discriminator (LLD)

At higher voltages 1800 - 2000 V the tube operates in corona mode, in this mode neutron counts are easier to distinguish from gamma rays. 

This neutron detector will work well in proportional mode with a GS-USB-PRO-HI or alternatively in corona discharge mode with a GS-SCHMITT-TRIGGER if a logic signal output is preferred. 

Note: The Schmitt trigger can be built into a GS-USB-PRO so no additional connections are required. 

This tube does not come with a moderator, but feel free to talk to us about how to DIY or allow us to make one up for you.
