AbstraktAbstract

We report on measurements of 1 and 1.5 MeV monoenergetic electrons with a Timepix3-based detector using a 0.5 mm thick silicon sensor. A 90Sr β-emitting radioisotope was used as the source of electrons, and a monochromator equipped with an adjustable magnetic field was employed to only pass electrons of desired energy into the detector. We provide experimental results of deposited-energy spectrum in the sensor and linearity of detected tracks. Alongside with the experiment, the whole system has been modeled in software and a Monte Carlo Geant4/Allpix2 simulation of the experiment has been carried out. Generally, we find a good agreement between the two.
