The Timepix4 is a pixelated and hybrid detection system developed by the Medipix4 Collaboration at CERN. It consist of a 448 x 512 pixel reading matrix which can be bump-bonded to a semiconductor sensor with square pixels at a pitch of 55 mu m. The Timepix4's ability to isolate individual particles and measure the energy they release in the sensor makes it a valuable tool for spectral imaging, capable of acquiring continuous energy spectrum images even in the presence of a high rate of incident events. This article presents a calibration method for the Timepix4 and evaluates the device's energy resolution using fluorescence photons produced with a micro-focus X-ray tube as a radiation source.

Abstract

The Timepix4 is a pixelated and hybrid detection system developed by the Medipix4 Collaboration at CERN. It consist of a 448 x 512 pixel reading matrix which can be bump-bonded to a semiconductor sensor with square pixels at a pitch of 55 mu m. The Timepix4's ability to isolate individual particles and measure the energy they release in the sensor makes it a valuable tool for spectral imaging, capable of acquiring continuous energy spectrum images even in the presence of a high rate of incident events. This article presents a calibration method for the Timepix4 and evaluates the device's energy resolution using fluorescence photons produced with a micro-focus X-ray tube as a radiation source.
