| PIRADUNEW – Perspektívne detektory ionizujúceho žiarenia pre nepokryté energetické okno neutrónov | |
| Perspective ionizing radiation detectors for the uncovered neutron energy window | |
| Program: | SRDA |
| Project leader: | Mgr. Zaťko Bohumír, PhD |
| Annotation: | The subject of the presented project is the optimization and preparation of semiconductor detection structuresbased on 4H-SiC and polycrystalline diamond suitable for neutron detection. As part of the project, single detectorswill be prepared and investigated, especially for neutron energies from 100 keV to several MeVs. There arecurrently few sensitive detectors in this area of neutron energy. The advantages of SiC and polycrystalline diamond are the high radiation and temperature resistance of structures. The high spectrometric capability of SiC detectors is also important, especially when detecting neutrons with energies below 1 MeV. Polycrystalline diamond is m ore affordable than SiC, and our first preliminary results show its promising detection properties, especially when detecting ionizing particles. Another advantage of both types of semiconductors is the low sensitivity to gamma radiation, which is almost always present in the event that neutrons are formed during a nuclear reaction. This gamma ray enhances the background and impairs the sensitivity of the detectors currently in use. Pixel sensors for the Timepix/Medipix reading chip will also be developed and investigated. Prototypes of the radiation camera will be tested and calibrated using a monoenergetic neutron source. |
