Performance of microchannel plate based detectors for <25 keV x rays: Monte Carlo simulations and comparisons with experimental results Open
We present the results of Monte Carlo simulations of the microchannel plate (MCP) response to x rays in the 250 eV to 25 keV energy range as a function of both x-ray energy and impact angle and their comparisons with the experimental resul…

Short-pulse photoneutron production on beryllium using the mercury pulsed power X-ray source Open
An x-ray beam can produce neutrons using beryllium as a photoneutron converter because of the relatively low 9Be(ɤ,n) reaction energy threshold. Previous photoneutron production simulations have focused on using a linear acceler…
