Abstract
The purpose of this work is the theoretical study of two dimensional detector used for X rays radiation. This detector is able to correct the parallax effect for variable detector-sample distance. An electrostatic study of this detector has shown that it was possible to construct absorption space for X rays where the parallax error could be corrected. A numerical method for Laplace equation solving has permitted to find optimal values of potential on conductors of absorption space to obtain a spherical electric field. Another part of this work consists of numerical simulation of signal in proportional detector using the Monte-Carlo method. However most of the work that has been done on the subject did not describe correctly the making of the signal during the first instants. We have described in this study all the details of the development of the electron avalanche and the signal. The results obtained from simulation are in good agreement with experimental results.
