Developments in gas detectors for synchrotron X-ray radiation
Abstract
New results on the physical limitations to position resolution in gas detectors for X-rays (approx. =3 to 20 keV) due to the range of photoelectrons and Auger electrons are discussed. These results were obtained with a small gap detector in which position readout was accomplished by using a very low noise centroid finding technique. A description is given of position sensitive detectors for medium rates (a few x 10(5) photons per second), using delay line readout, and for very high rates (approx. =10(8) photons per second), using fast signal shaping on the output of each anode wire.
