Title Initial studies in the modelling of a position resolving calorimeter detector
Abstract In this report we describe some initial results in the modelling of a position resolving calorimeter detector. The ideas behind the device are based on those of the microcalorimeter. These detectors use the heat generation of an X-ray event to provide information on the event's time and position when assembled into an array. In this report we consider a larger detector which uses the same thermal ideas of the microcalorimeter but also utilises multiple thermistors to determine the event position on the detector's surface. This first attempt at modelling makes the basic assumption that the heat transport can be represented through a simple linear diffusion process and through that the times at which the temperature change reaches the edge sensors can be used to determine the position of the event . A simple idealised device has been used to assess the potential modelling these devices to aid their design and development. The report develops a finite element model of the device and performs a series of numerical experiments. The results of these experiments are compared with a simple analytical model. Two methods of determining the event position are presented: one based on the analytical solution and a second using neural network.
