WebGas-filled detectors can be operated in several regimes. At low applied voltage, no gas multiplication takes place, and the detector functions as an ion chamber. At some minimum voltage, avalanches begin to form, marking the start of the proportional-counter region, and they become more vigorous as the voltage increases. Finally, at high ...
