Switching Frequency Extended Range Geiger Detection System and Method

摘要

A Geiger-Mueller charge particle rate measurement system includes a clock management unit in combination with multiple oscillators and rate feedback controller to allow for reactive switching between the different oscillator frequencies to optimize system use. Controlling the clock management unit to send the appropriate frequency (clock signal) to the timers in response to measured rate date from the rate feedback controller facilitates operation at different clock speeds, which helps reduce power consumption when operated at lower speeds.

1. A radiation measurement system comprising:
a single Geiger-Mueller tube for detecting one or more radiation particles; a rate detection module for receiving detection data and determining a radiation measurement rate therefrom; a rate feedback controller for receiving the radiation measurement rate from the rate detection module and determining if a change to the radiation measurement rate should be made; and a clock management unit for controlling at least two oscillators having different frequencies responsive to rate feedback data from the rate feedback controller.
