Abstract: This presentation outlines the gradual development of Compton camera, evolving from semiconductor pixel detectors based on Timepix3. The primary objective is to deploy this camera for characterization of bremsstrahlung emissions produced by runaway electrons on the Golem tokamak.
Presentation commence with an introduction of the Golem tokamak and the challenges posed by runaway electrons and seamlessly transitions to the AdvaPix Timepix3 detectors. The following is a description of the correction of a phenomenon called "Timewalk" and the calibration of the depth of interaction in the sensor using the trajectories of the detected muons. These calibration processes are incorporated into the subsequent data processing using the Compton camera.
The initial validation of the camera's display capabilities involves measurements with ionizing radiation standards, for example 22Na and 137Cs. In the end of the presentation are images obtained from measurements conducted in enviroment of the Golem tokamak.
