Study and application of hole structures as gas gain devices for two dimensional high rate X-ray detectors

Recent developments in hole structures seem to be a promising enrichment for gas-filled photon counters. Up to now, only few investigations of the performance and limitations of these structures have been carried out. In this work a micro-hole structure is presented together with investigations focu...

Description
Summary:Recent developments in hole structures seem to be a promising enrichment for gas-filled photon counters. Up to now, only few investigations of the performance and limitations of these structures have been carried out. In this work a micro-hole structure is presented together with investigations focused on applications with position sensitive pressurized X-ray detectors for synchrotron radiation. In particular, position resolution, gas gain, rate capability, drift field influence and pressure behavior have been studied. In addition, first two dimensional X-ray images have been measured using a gas amplifying micro-hole structure in combination with a resistive position encoding structure. Since different types of hole structures were tested, predictions of structure geometries adapted for specific applications were carried out.
