proportional gas-scintillation counter
A @P04885@ coupled to an @UT07492@ sensitive @P04626@. Initial electrons produced by the interaction of the high-energy photon with the counter fill-gas are accelerated by a high electric field where they acquire sufficient energy to excite the noble gas atoms. The resulting UV radiation is observed by a @P04626@.
