Gas Scintillation Proportional Counters

Gas Proportional Scintillation Counter

Gas scintillation proportional counters (GSPC), developed in 1972 20 , offer the advantage of an enhanced energy resolution when compared with proportional counters. In conventional proportional counters, the charge generated by an ionizing event is multiplied in a high electrical field. The amplification grows exponentially with the number of ionizing collisions of an electron in the high field region. Only 14 ionizing collisions result in a charge multiplication of four orders of magnitude....
