LXXXI. A high precision pulse height analyser of moderately high speed

Summary A pulse height analyser is described suited particularly to the requirements of nuclear physics. Information is stored in a supersonic delay line and displayed on a cathode ray tube. The accuracy of channel width and the linearity of response are both one part in a thousand. The number of channels and storage capacity per channel may be varied at will to give 60 channels of up to 106 pulses, 80 channels of up to 3 × 104 pulses, or 120 channels of up to 1023 pulses. The maximum counting rate is 1600 per second.
