We demonstrate use of a charge-coupled device (CCD) with sub-electron readnoise performance as a non-dispersive X-ray spectrometer. The exceptionally low readnoise (0.9 electrons rms) was achieved by applying a floating gate output amplifier with 16 readouts per pixel. The soft X-ray quantum efficiency was enhanced over other front-side illuminated devices by using a novel thin-poly gate structure. The combination of sub-electron noise and good soft X-ray quantum efficiency have enabled us to detect photons in the EUV energy range (Eread more

Parameter estimation in X-ray astronomy
TL;DR: In this paper, the problems of model classification and parameter estimation are examined, with the objective of establishing the statistical reliability of inferences drawn from X-ray observations, and a procedure based on minimizing the chi/sup 2/ statistic is recommended; it provides a rejection criterion at any desired significance level.

TL;DR: In this paper, the pair-number probability distribution of a particle with energy $E$ ultimately creates pairs, is calculated recursively with increasing energy, and the first and second moments of the distribution yield pair-creation energy, the Fano factor, and quantum yield for semiconductors.

TL;DR: In this paper, a Monte Carlo model of X-ray energy loss with respect to the energy and temperature dependences of soft X-rays with silicon was proposed, where the average energy required to create an electron-hole pair and the Fano factor were treated as material constants.
