High Spatial Resolution Multiwire Proportional Chamber Systems Using Electromagnetic Delay Line Readouts.
Abstract
The report describes results of an investigation to develop multiwire proportional chamber systems using electromagnetic delay lines for high resolution cosmic ray experiments. The delay line used is a plexiglas core type, with a delay constant of 7 nsec/mm. The interpolation properties of this readout scheme resulted in a measured spatial resolution of 75 microns (HWHM) using iron-55 X-rays and a wire spacing of 1 mm. Tracking accuracy over a 6 mm region near the center of the chamber was better than plus or minus microns when fitted to a linear spatial dependence combined with a sinusoid of wire-spacing periodicity.
