Abstract

The Timepix4 is a newly developed detector featuring improved performance compared to its predecessor Timepix3. This detector can be used to measure Time of Flight of protons, which are used in proton therapy of tumors and cancers. However, each pixel of the detector exhibits a dead-time immediately after a detection has been made, during which it cannot detect a passing proton. It is thereby of interest to find how many protons go undetected. This percentage of dead-hits depends on the beam intensity hitting the detector. As this research is being done considering the local AGOR cyclotron, only proton fluxes which this cyclotron can produce were considered. Using Python, it was found that for fluxes increasing from 10^4 protons/cm^2/s to 10^8 protons/cm2/s, the percentage of dead-hits increases from 0% up to 1.82%.
