Validation of spallation neutron production and propagation within Geant4
Using simulations to understand backgrounds from muon-induced neutrons is important in designing next-generation low-background underground experiments. Validation of relevant physics within the Geant4 simulation package has been completed by comparing to data from two recent experiments. Verification focused on the production and propagation of neutrons at energies important to underground exp...
متن کاملNeutron Imaging at Spallation Neutron Sources
Neutron imaging is a powerful method for non-destructive investigations where the high penetration through metals and the high contrast for hydrogenous materials is exploited in particular. The complementary to X-ray studies is a clever alternative in many cases of scientific and industrial applications. Reactor based neutron sources are becoming less available, caused by the shutdown of aged f...
متن کاملLinac-driven Spallation-neutron Source*
Strong interest has arisen in accelerator-driven spallationneutron sources that surpass existing facilities (such as ISIS at Rutherford or LANSCE at Los Alamos) by more than an order of magnitude in beam power delivered to the spallation target. The approach chosen by Los Alamos (as well as the European Spallation Source) provides the full beam energy by acceleration in a linac as opposed to pr...
متن کاملThe Spallation Neutron Source Project
The SNS is a "joint-venture" project of five DOE National Laboratories, aimed at building the world's most powerful accelerator-based pulse spallation source. At its planned 2 MW operation, it will produce neutron fluxes at least a factor of ten greater than Rutherford Appleton Laboratory’s ISIS, currently the world’s leading spallation source. The current design of the SNS, shown in Figure 1, ...
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...
