Proportional counter vs gm counter

Webb17 apr. 2024 · 4. The Geiger Counter is an instrument used for measuring ionizing radiation. It detects ionization radiations such as α-particles, β- particles and γ-rays using the ionization effect produced in a Geiger-Müller tube. It is perhaps one of the world’s best-known radiation detecting instrument. 5. The proportionality between the energy of the charged particle traveling through the chamber and the total charge created makes proportional counters useful for charged particle spectroscopy. By measuring the total charge (time integral of the electric current) between the electrodes, we can determine the particle's kinetic energy because the number of ion pairs created by the incident ionizing charged particle is proportional to its energy. The energy resolution of a proportional co…

WebbIn proportional counters this results in a decrease in output signal strength. For GM counters the problem is not of signal strength, but rather the spread and sustainment of the avalanche. With too much absorption of the electrons, this process may die out too soon and the resulting pulse may not be high enough to pass the discriminator threshold.
