Description
Modern low-energy H-/D- injectors are used extensively in many large, accelerator-based, user facilities operating worldwide. Beams of these ions are used to fill circular accelerators and storage rings, to enable efficient extraction from cyclotrons and to double proton energy output from a tandem accelerator. The injector consists of an ion source, a Low Energy Beam Transport (LEBT) section and typically, a Radio frequency Quadrupole (RFQ) accelerator. Such facilities include the US Spallation Neutron Source (SNS), Japan Proton Accelerator Research Complex (J-PARC), Rutherford Appleton Laboratory (RAL-ISIS), Los Alamos Neutron Science Center (LANSCE), Fermi National Accelerator Laboratory (FNAL), Brookhaven National Laboratory (BNL), the CERN LHC injector, the Chinese Spallation Neutron Source (CSNS), Tri University Meson Facility (TRIUMF) as well as numerous installations of D-Pace deployed injector systems used mainly with cyclotrons delivering beams of deuterium. In addition, several future facilities and upgrades are being planned which will likely also utilize enhanced H- injectors. This report will first provide a simple description of these injectors, their operational parameters and discuss some of the associated R&D efforts. Specific attention will be paid to the RFQ component of the injector as it has not been covered in previous similar reviews [1]. A tabulation of each facility’s RFQ’s manufacturer, design and operating parameters, beam acceptance (Twiss parameters) and performance metrics will be provided.
