A Microwave Gas Discharge Counter for the Detection of Ionizing Radiation

摘要: Characteristics of a gamma‐ray counter making use 3000‐megacycle gas discharge in coaxial mode cavity resonator are described. The breakdown gases at these frequencies does not depend upon secondary effects. Since the is controlled by positive ions, shorter and resolving times than those Geiger‐Muller realized. In high frequency discharge, ambipolar diffusion controlling factor loss electrons. A d.c. clearing field superimposed on a.c. to eliminate electrons rapidly. quenching agent present suppress electron emission from ion bombardment walls. extinguished reducing magnetron power electronically. plateau sensitivity characteristics similar counter.
