| Popis: | We studied the performance of advanced semiconductor detectors to measure reactor antineutrino with the potential to drastically improve efficiency and lower existing thresholds of detectable incident-antineutrino-energy. Recent developments, such as those by the Mitchell Institute Neutrino Experiment at Reactor (MINER) experiment at Texas AM however, it is shown that silicon is sensitive to lower antineutrino energies. It is found that a 100-eV nuclear recoil in germanium semiconductor detectors can be produced by a minimum incident energy of 1.84 MeV antineutrinos, and in silicon by 1.14 MeV antineutrinos. For the lower threshold, a 20-eV nuclear recoil in germanium semiconductors can be produced by a minimum incident energy of 0.82 MeV antineutrinos and in Si by 0.51 MeV antineutrinos. Lowering the detector response energy sensitivity equips us with newer techniques for nuclear fuel monitoring. |
