Second order reflection from crystals used in soft X-ray spectroscopy
Nukleonika, 2015 In this note the ratio of the second to the first order reflection is determined for the KAP and PbSt crystals, for wavelengths corresponding to the Al K-line emission. The source of the radiation was a low-voltage stabilized X-ray tube.

Proportional Counters for Demonstration Experiments [PDF]
American Journal of Physics, 1957 Proportional counters suitable for demonstration purposes are described, and some experiments to illustrate counter operation are discussed. The charge carried by the positive ions produced in the multiplication process, and the localization of the avalanche, is revealed in a special proportional counter whose cathode is covered by a layer of polythene.

Proportional Counters and Microchannel Plates
, 2022 Developed right at the beginning of the space age in the 1940s, the proportional counter was the first detector used in X-ray astronomy and stayed its workhorse for almost four decades. Although the principle of such a detector seems to be rather simple, over time it underwent considerable performance improvements and the lifetime under orbital ...

Design of a Rise Time Discrimination Circuit for X-ray Proportional Counter [PDF]
Journal of Astronomy and Space Sciences, 1995 It is possible to distinguish X-rat events from non X-ray events in proportional counters using the method of rise time discrimination (RTD). In order to subtract non X-ray background, we have developed a simple RTD circuit which will be applied to the ...
