Time characteristics of a multi-wire 4 pi beta-counter.
In order to examine the time characteristics of a multi-wire 4 pi beta-counter for the 4 pi beta-gamma coincidence system, measurement was made on the time distributions of the pulses from the individual anodes. The time distribution obtained by each anode was explained mainly by the distribution of primary ionizing position. A similar time distribution was obtained in the case that the alternating wires cathodes, when the individual anodes had the same effective detection region. Spurious pulses were observed in 90% argon plus 10% methane mixture at the end voltage of the plateau region and not methane gas.
