Abstract
A new coincidence device using crystal diodes has been developed. The new circuit does not necessitate equalizing and can be used for pulses with an amplitude spread of two orders of magnitude. The principle of the new circuit is to compare two measurements: one made in one of the channels, and the other made between the two channels. Resolving times down to 3×10−10 sec have been obtained, which represent an improvement of one order of magnitude over former circuits. The improvement in the sensitivity also turned out to be about one order of magnitude. The new circuit should be useful in nuclear experiments in determining decay times, disintegration rates, and for the reduction of noise in scintillation counters.Keywords
