The Compensation Capacitor

Normally, the Geiger tube delivers a sharp short pulse, with an abrupt descending path, as the quenching gas very quickly neutralises the conductive ions, and so terminating the current flow. The uRADMonitor pulses appear with a slightly rounded tip because an extra capacitor is added in the circuit, named the “compensation capacitor”. All uRADMonitor model […]
