Geant4 simulation of the calorimetric application of the ALPIDE CMOS sensor
Summary
In this research the calorimetric application of the ALPIDE CMOS sensors has been studied through Geant4 Monte-Carlo simulations of a prototype for this sensor. Simulations for 4 and 24 layers of the prototype have been done for electrons of 50, 100, 150 and 180 GeV and simulations for one layer of the prototype with a tungsten absorber in front of it that is 0, 8, 20 and 28 mm thick. These results of tests for these prototypes can be compared to these simulations. The results show that these sensors are capable of measuring high energy particles and that the particle showers behave as expected. The results also show a lower secondary peak in the hits per event distribution for simulations of the 24 layer detector, which is likely caused by the small gap between the two ALPIDE chips used.
