SPHERICAL PROPORTIONAL COUNTER OF GAMMA RADIATION

摘要

Spherical proportional counter of gamma radiation consisting of a spherical thin-walled casing constituting the counter's cathode and anode situated inside in the form of a thin wire extended along the diameter inside the spherical cathode and mounted, with its ends, in grips connected to the anode's baffles characterized in that in each of the two areas of the spherical cathode (1) constituting the surroundings of the ends of the anode (2), which is diametrically located, an additional protective electrode (3) is located, which is in the form of a sleeve placed concentrically with respect to the anode's end and a grip (4), in which such an end is fastened, and the additional protective electrode is mounted in a hole, preferably formed in the wall of the spherical cathode and is isolated from the cathode (1) with the use of a sleeve insulator (5), and the additional protection electrode (3) is isolated from the anode's baffle (6) with the use of the insulator of the additional electrode (7).IMAGE
