We have built up a computer simulation of detection mechanism in diamond detectors. The diamond film (diamond detector) is simulated by a grid; at this stage the grid is two dimensional. Different electrode configurations for the detector are considered, including a single electrode, parallel plates, and a strip-pad geometry. The charge distribution on the electrodes has been calculated and hence the electric potential and electric field vector at each grid point within the diamond detector. Alpha particles produce a large number of electron-hole pairs and their path to the electrodes can be calculated. By applying the Shockley-Ramo theorem, we calculate the signal induced on the electrodes. We compare the response of diamond detector as a function of time in the different electrode configurations and with different trapping-de-trapping properties of the diamond films.
