Front-end electronics for high rate, position sensitive neutron detectors
Advanced neutron detectors for experiments at new spallation sources will require greater counting rate capabilities than previously attainable. This necessitates careful design of both detector and readout electronics. As part of a new instrument for protein crystallography at LANSCE, we are constructing a detector whose concept was described previously (IEEE Trans. Nucl. Sci. NS-46 (1999) 191...
متن کاملThe Use of Ge Detectors for (n,xn) Cross-section Measurements at Intense and Low Frequency Pulsed Neutron Beams
In Accelerator-driven Systems (ADS), (n,xn) reactions have more importance than in conventional reactors. Indeed in ADS the external neutron flux provided by the accelerator is produced by spallation reactions, which means that its spectrum extends to several hundreds of MeV. On the other hand, the cross-sections of these reactions are often badly known. This is due in part to the fact that few...
متن کاملThe Fundamental Neutron Physics Beamline at the Spallation Neutron Source
The Spallation Neutron Source (SNS), currently under construction at Oak Ridge National Laboratory with an anticipated start-up in early 2006, will provide the most intense pulsed beams of cold neutrons in the world. At a projected power of 1.4 MW, the time averaged fluxes and fluences of the SNS will approach those of high flux reactors. One of the flight paths on the cold, coupled moderator w...
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 کاملNovel 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...
