We present the characterization of a highly segmented “large area” hybrid pixel detector (Timepix3, 512 × pixels, pitch 55 µm) for application in space experiments. demonstrate that nominal power consumption 6 W can be reduced by changing settings Timepix3 analog front-end and reducing matrix clock frequency (from 40 MHz to 5 MHz) 2 (in best case). then comprehensive study impact these changes on particle tracking performance, energy resolution time stamping precision utilizing data measured at Super-Proton-Synchrotron (SPS) CERN Danish Center Particle Therapy (DCPT). While slower sampling measurement mitigated prolongation falling edge signal, we find reduction from 1.8 ns standard settings) 5.6 low-power), which is further lower (e.g., MHz, digital low-power operation) 73.5 ns. have studied temperature dependence ambient temperatures between −20 °C 50 separately different settings.
