Feasibility of Using Electronic Quenching to Eliminate Halogen Gas in Geiger-Muller Detectors in Aircraft Oil Gauging Systems.
Abstract
The feasibility of electronic quenching was studied for Geiger-Muller (GM) radiation detectors used in aircraft oil gauging systems. A solid-state, variable-parameter quenching circuit was used which employed a multivibrator and a high-voltage transistor to reduce the applied voltage on the detector. The GM detectors which were tested included halogen-quenched counters formerly used in aircraft oil systems, as well as locally manufactured GM tubes filled to 100-200 torr of combinations of Ar, CO sub 2, H sub 2, N sub 2, and Ne. Experiments with operational halogen-quenched tubes indicated that with electronic quenching, an increased voltage operating range and tube counting lifetime are possible. The results for inoperable halogen-quenched detectors and for detectors containing no quenching gas were mostly inconclusive.
