ABSTRACT
Nuclear instruments are designed to acquire and produce meaningful signals from radiation detectors. The detector is the active element used to absorb radiation particles and subsequently produce a recognizable signal associated with each event. Detectors may rely upon measurable phenomena, such as electronic, thermal, or visual changes. Instrumentation for the nuclear industry was specified in a 1964 report TID-20893 to the US Atomic Energy Commission to what are referred to as Nuclear Instrument Modules. The US Atomic Energy Commission (AEC) convened a meeting of representatives from several national laboratories on Feb. 26, 1964 to determine if such a task was of interest to the laboratories. In agreement, the AEC Committee on Nuclear Instrument Modules was established, composed of members from all AEC national laboratories and a few other prominent nuclear laboratories. The high voltage power supply, as the name implies, supplies high voltage to the detection device, and can supply it with either positive or negative polarity.
