Developments in Gas Detectors for Synchrotron X - Ray Radiation
نویسنده
چکیده
New results on the physical limitations to position resolution in gas detectors for X-rays ( 3-20 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 photons per second), using delay line readout, and for very high rates ( photons per second), using fast signal shaping on the output of each anode wire.

Cryogenic X-ray detectors for synchrotron science.
Cryogenic detectors operated at temperatures below 1 K offer an order of magnitude higher energy resolution than conventional semiconductor-based energy-dispersive detectors, and orders of magnitude higher efficiency that grating spectrometers. Initially developed for astrophysics applications, these detectors are increasingly used in synchrotron-based research, both for detector characterizati...

متن کاملPixel detectors for diffraction-limited storage rings
Dramatic advances in synchrotron radiation sources produce ever-brighter beams of X-rays, but those advances can only be used if there is a corresponding improvement in X-ray detectors. With the advent of storage ring sources capable of being diffraction-limited (down to a certain wavelength), advances in detector speed, dynamic range and functionality is required. While many of these improveme...
متن کاملRecent developments in X-ray imaging with micrometer spatial resolution.
X-ray detectors for imaging with a spatial resolution in the micrometer and submicrometer range have been developed at synchrotron radiation sources since 1996. The detectors consist of a scintillator, a light microscopy optic and a charge-coupled device (CCD). The scintillator converts part of the X-ray stopped by a material into a visible-light image which is projected onto the CCD by the lig...
