Modeling micro-channel plates as astronomical detectors of UV radiation

Abstract

The World Space Observatory (WSO) is a space-based ultraviolet (UV) telescope under development by Russia and Spain. Mexico is formalizing its participation in the development of components for some of the instruments on board, such as the detectors that are discussed in this work. In particular, this paper describes a first approach to a computational model of micro-channel plates (MCP), which are used for astronomical purposes. The model is used to describe the behavior of the secondary emission yield (SE yield) and its relationship with the gain obtained by the MCP. Furthermore we want to model the generation of the detected particle clouds generated at the output of the MCP, after which a segmentation algorithm is applied to obtain the optimal contour around these clouds and the corresponding centroids.
