The Lawrence Berkeley National Laboratory (LBNL) is designing and building the 2.5 MeV front end injector for the Spallation Neutron Source (SNS). This injector comprises an H/sup -/ ion source, a low energy beam transport line (LEBT), a radio-frequency quadrupole (RFQ) and a beam transport line designed to provide fast chopping of the beam. The RFQ is designed to accelerate the Hbeam from the energy of 65 keV to 2.5 MeV, while bunching it at 402.5 MHz. This high duty factor (6%) structure is… 
DETAILED MODELING OF THE SNS RFQ STRUCTURE WITH CST MICROWAVE STUDIO
We report detailed RF modeling on the SNS RFQ structure using CST Microwave Studio code. Due to the complexity of the RFQ structure, a three-dimensional model with large mesh ratio is required to

Many new high-current accelerators use both room- temperature and superconducting structures. While it is clear that a low-beam-current, high-duty-cycle accelerator should use superconducting
