摘要
Cylindrical MWPCs have been constructed with anode diameters of 240-430 mm and a length of 750 mm. Cathode strips run helically with 38 degree -61 degree to the anode wires, and the induced charges were read out by ADC. Both the anode and the cathode efficiency were well above 99%. The resolution ( sigma ) for the longitudinal position of the avalanche was 0. 6 mm by the center of gravity method, if the cathode was read out per 12 mm width by summing two adjacent cathode strips.
