Description

Allpix-Squard is Geant4 based modular framework that was initially designed for the simulation of silicon detectors in high-energy physics but now its sensor material capability and applicability have been extended. My work is intended to check the validity of the implementation of Diamond material in Allpix-squared. Diamond sensors have specific applications in high-energy physic because of their faster signal generation, thermal properties, and ability to operate in harsh conditions. To test the implementation, the basic charge carrier properties e.g. low field mobility, saturation velocities, and drift velocities of pure single-crystal diamond material are obtained at different applied voltages via simulation and compared with the standard literature data. From our initial results, it is concluded that diamond implementation is not valid in Allpix-squared, and in the first step, new parameter values for the Caughy mobility model have been added for diamond sensors. Further investigations are necessary in the case of polycrystalline diamond sensors and their operation in high-radiation environments. The full implementation of Diamond sensor material will significantly contribute to the task of R&D of Diamond sensors by making the simulated prototype simply possible. I will present the ongoing status of the implementation of the diamond as detector material in Allpix Squared.
