Position-sensitive proportional counter for the Bragg Crystal Spectrometer on Solar-A
Abstract
The gas proportional counter used for X-ray detection on the Solar-A Bragg Crystal Spectrometer Instrument is described. The sealed detector utilizes a multianode geometry together with a wedge and wedge (or backgammon) cathode pattern to provide one-dimensional imaging along the dispersion axis. The development program has now arrived at a design for the prototype detector. Results of the imaging performance, energy resolution, and count-rate capability are psesented.
