摘要

A position-sensitive MWPC detector based on LC delay-line readout has been developed for precise position measurement for experimental studies of nuclear physics.The detector consists of six electrode wire planes,which is placed in a gas chamber with a sensitive area of 100 mm×80 mm.Fig.1 shows a schematic drawing with the disposition of the six wire planes.This structure has two anode planes,each is sandwiched between two cathode planes,and the anode-cathode spacing is 4 mm.The anode plane,consist of 15 m gold-plated tungsten wires with a pitch of 3 mm.The two cathode pairs are positioned in such a way that the wires are perpendicular to each other in order to give positions at X and Y directions.The cathode planes in each pair are parallel each other in the orientation of the wires,which are made of 30 m stainless steel wires with a pitch of 0.5 mm.
