Novel microstrip detectors and data acquisition strategies for thermal neutron imaging at the next generation pulsed neutron sources
For thermal neutron imaging at the next generation of high-flux pulsed neutron sources microstrip detectors with solid state neutron converter foils are presently being developed in different laboratories with the objective to improve the resolution and count rate limits by orders of magnitude in comparison with the presently available neutron detector types, in particular compared to multiwire...
متن کاملNeutron Detectors
Mechanisms for detecting neutrons in matter are based on indirect methods. Neutrons, as their name suggests, are neutral. Also, they do not interact directly with the electrons in matter, as gamma ray$ do. The process of neutron detection begins when neutrons, interacting with various nuclei, initiate the release of one or more charged particles. The electrical signrdsproduced by the charged pa...
متن کاملCharacteristics of Fabricated SiC Neutron Detectors for Neutron Flux Monitoring
An SPND (Self-powered Neutron Detector) is commonly used for neutron detection in NPP (Nuclear Power Plant) by virtue of un-reactivity for gamma-rays. But it has a drawback, which is that it cannot detect neutrons in real time due to beta emissions (about > 48 s) after reactions between neutrons and Rh in an SPND. And Generation IV reactors such as MSR (Molten-salt reactor), SFR (Sodium-cooled ...
متن کاملCompact Neutron Generator Development and Applications
The Plasma and Ion Source Technology Group at the Lawrence Berkeley National Laboratory has been engaging in the development of high yield compact neutron generators for the last ten years. Because neutrons in these generators are formed by using either D-D, T-T or DT fusion reaction, one can produce either mono-energetic (2.4 MeV or 14 MeV) or white neutrons. All the neutron generators being d...
متن کاملMicrostructured semiconductor neutron detectors
Perforated semiconductor neutron detectors are compact diode detectors that operate at low power and can be fashioned to have high thermal neutron detection efficiency. Fabricated from high-purity Si wafers, the perforations are etched into the diode surface with ICP-RIE and backfilled with LiF neutron reactive material. The intrinsic thermal neutron detection efficiency depends upon many facto...
