摘要：

New high rate multiwire gas proportional counters for X-ray detection under development at Daresbury require low noise, fast preamplifiers to achieve minimum dead time. We present a design for a fast preamplifier with a rise time of 8 ns, noise better than 1300 electrons rms and a gain of 4.8 muV per electron. Results of a computer simulation run to predict the optimum differentiate constant needed to ensure a short dead time are also presented. The application of this preamplifier on a fast multiwire linear detector is discussed and results are presented.
