This paper discusses the process of functional aging of Geiger-Muller counters.Two types of lacrosse Shin Guards Geiger-Muller counter chambers were characterized in an experiment using a combined constant voltage.Chamber A had a coaxial geometry and chamber B had a plan-parallel geometry.The experimental results indicate that the aging process was faster in the case of chambers with a coaxial geometry.
The results are explained based on the process of Nylon/Synthetic Headstalls electrical discharges in gasses.
