Characteristics of multiwire proportional counters with delay line readout for minimum ionizing particles

Description: The effects of gas mixture and chamber thickness on the gain and pulse shape of a multiwire proportional counter with delay line readout were studied. The primary concern was with optimizing the position accuracy for high-energy particle physics applications. The best results, both from the point of view of chamber gain and the risetime and uniformity of the delay line pulses were obtained with a 4 mm gap chamber run on a mixture of 30% carbon dioxide and 70% argon. It was found necessary to bias the outer grids negative with respect to ground to prevent electrons in the drift regions from migrating into the multiplication region and spoiling the delay-line pulse shape.
