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 nsecmm. 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.
