Photomultiplier-Based Scintillation Radiation Detectors of Increased Sensitivity and Time Resolution for Measurements under Conditions of High Electromagnetic Interference

Abstract

Scintillation detectors for detecting X-ray, gamma, and neutron radiation with time resolutions of 3–4 ns and having high noise stability have been developed. The detector housings are shielded from the strong electromagnetic interference produced at the moment of discharge. The detector design features an original voltage divider. With these detectors, the parameters of the high-energy radiation from a megavolt atmospheric nanosecond discharge can be studied at the limit of sensitivity of this class of devices.
