STUDY OF SPARK COUNTERS OF THE ROSENBLUM TYPE FOR COUNTING $alpha$ PARTICLES AND NEUTRONS
Characteristics of the Rosenblum type spark counters were studied experimentally. In the case of a single-wire counter, the number of counts was investigated when the alpha -particle source was moved parallel to the cathode plate, in relation to voltage applied to the anode wire, and also when the source was moved perpendicularly to the cathode plate. The effects of temperature, pressure, and humidity of the surrounding air on counts were investigated, and the efficiency of counting of alpha particles was estimated. Experiments were also carried out for a multiple-wire coun ter. A counter with 14 anode wires was constructed, and it was found that uniformity of counting through the whole acting region would be greatly improved by inserting a high resistance in series with each wire. A neutron detector was constructed by putting a boron-coated glass plate above the multiple wires and surrounding the counter with paraffin. (auth)
