Paper Abstract

A new photon-counting area detector, based on parallel-plate gas amplification with a resistive anode and remote readout electrode is described. The detector is sealed and has sensitive area of 14x14 cm2. The detector is unique in its ability to achieve high gain at high counting rates. A local counting rate >10e5 counts/mm2-sec has been achieved at a gain of 105 in a radiation-hard, non-polymerizing gas mixture. The global readout rate is limited by the delay line and electronics to <106 counts/sec but more sophisticated readout schemes should allow this rate to be increased by more than an order of magnitude. The operating characteristics of the detector are described and preliminary x-ray diffraction data are presented.
