Modelling the behaviour of microchannel plates using CST particle tracking software

Abstract Photon counting detectors are essential for many applications, including astronomy, medical imaging, nuclear and particle physics. An extremely important characteristic of photon is the method electron multiplication. In vacuum tubes such as photomultiplier microchannel plates (MCPs), secondary emission (SEE) provides multiplication through an accelerating field across dynode(s). A significant cascade can be observed in these structures which routinely used industry research. Both devices have been thoroughly tested experimentally. Developing new MCP designs expensive time consuming so ability to simulate will provide advantages instrument designers manufacturers. There are, however, challenges accurately simulating MCPs, with geometrical variables consider well material SEE properties. The process probabilistic, MCPs having a very high gain, computational resource required resulting output model. our research we illustrate how this achieved by developing model using Computer Simulation Technology (CST) Studio Suite software. consists charged source, small seven-pore structure (including electrodes, resistive emissive surfaces), readout anode, appropriate potentials applied components We present simulation results from modelled demonstrate performance, compare those predicted theory. Our goal expand identify optimum parameters, various science novel materials optimise detector performance.
