Proportional counters for the localisation of ionising radiation

Abstract

Gas proportional counters which can be used for the localisation of ionising radiation in one or two dimensions are described. The technique of charge division on a resistive electrode is used to obtain position information, this electrode being the anode in the linear detector. In two dimensions the counter signal is obtained in a new way - from two induction grids placed between the anode and the cathode, each grid providing position information in one direction. Application of the two dimensional counter for X-ray imaging is illustrated. These counters combine ease of readout with good spatial resolution; in the one dimensional detector the standard deviation of positron measurements can be 0.04% of the sensitive length.
