Ion source antenna development for the Spallation Neutron Source
The operational lifetime of a radio-frequency ~rf! ion source is generally governed by the length of time the insulating structure protecting the antenna survives during exposure to the plasma. Coating the antenna with a thin layer of insulating material is a common means of extending the life of such antennas. When low-power/low-duty factor rf excitation is employed, antenna lifetimes of sever...
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 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 کاملA High Intensity Proton Source for the European Spallation Source Facility
Along the last 25 years, INFN-LNS has gained a relevant role in R&D of plasma-based ion sources. The laboratory is currently involved in the construction of the Proton Source and Low Energy Beam Transport (LEBT) line for the European Spallation Source. ESS – based on a 2.0 GeV, 62.5 mA proton accelerator for neutron production – will be a fundamental instrument for research and applications. Th...
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...
