Imaging Pin Detector - a Simple and Effective New Imaging Device for Soft X-Rays and Soft beta Emissions

摘要

The development of a new bidimensional imaging detector system for soft x and beta radiations is reported. Based on the detection of the differential induction signals on pickup electrodes placed around a point anode (or pin) in a gas avalanche detector, the system described has achieved a spatial resolution of better than 1mm fwhm over a field of 30 mm diameter while preserving excellent pulse height resolution (20% fwhm for 5.9keV X-rays). The present device offers considerable potential as a cheap and robust imaging system for applications in X-ray diffraction and autoradiography. (Atomindex citation 16:035200)
