Activation Type Pulsed Neutron Radiation Detector with Continuous Recording of Registered Pulses of Secondary Electrons in Real Time

A detector of pulsed neutron radiation of the activation type with continuous recording of registered pulses of secondary electrons in real time is described. As activation material, 0.3-mm-thick silver foil is used. An industrial grade SBM-19 gas-discharge Geiger–Muller counter, sensitive to hard beta and gamma radiation, was used to register secondary electrons. The recording interval of the accumulated number of registered secondary electron pulses is 10 s. The circular memory buffer used to record the secondary electron pulses is 16 MB, providing continuous recording for 2.5 years. A modern LiSOCl₂ galvanic cell with a voltage of 3.6 V and a capacity of 2.1 A h was used as a power source for the pulsed neutron radiation detector. The estimated operating time without replacing the battery is 5 years.
