Název v původním jazyce

Neutron energy measured by Time-of-Flight technique with triggered MiniPIX-Timepix3 detector with Si and SiC sensors

Popis výsledku v původním jazyce

For fast neutron sources, such as compact neutron generators, it is desirable to have knowledge and ideally directly measure the energy spectrum of the generated neutrons. For neutrons, the produced radiation field, and the neutron energy spectrum, at a specific location from the source, can be altered by the distance to the source and become even significantly distorted by surrounding material - e.g. walls and the floor of the laboratory. To achieve this goal, we make use of Time-of-Flight (ToF) technique, which has been implemented on the Timepix3 detector operated highly integrated readout electronics as a miniaturized radiation camera MiniPIX-Timepix3. Equipped with a silicon sensor, the Timepix3 ASIC chip provides fast timing response of individual pixels the nanosecond level. In this work, we use two Timepix3 detectors with a silicon sensor of thickness 300 mu m and a segmented neutron conversion mask, intended for both thermal and fast neutrons with a 65 mu m thick silicon carbide (SiC) sensor. Demonstration and evaluation of the technique are provided by measurements with a compact neutron D-T pulsed generator at VSB-TU Ostrava laboratory which produces mono-energetic 14 MeV neutrons.
