Title: Position-sensitive proportional-counter system for use in the Enge split-pole spectrograph

Abstract

A variety of position-sensitive single-wire proportional counters with lengths up to 90 cm have been built and tested in the focal plane of the Enge split-pole spectrographs at the Argonne tandem accelerator and cyclotron. This report, which describes the counters, the associated electronics, and the data-handling procedures, is intended as an operating manual for general use of the system. Under ideal experimental conditions, the spatial resolution of the counters is about 1 to 1.5 mm (FWHM), dependent on the energy loss of the incident particle in the counter. The spatial response of the counters is linear to within 0.5% of the active length. Furthermore, the system contains a conventional proportional counter, behind the position counter, designed to provide particle identification based on the energy lost in the counter. Pulses from the two counters are normally analyzed in coincidence to provide excellent particle discrimination. Examples of typical experimental results are also presented.
