    Research output: Contribution to journalArticlepeer-review


    This paper describes the electromagnetic and mechanical properties of a 150 MHz ?/4, 3-gap structure with two loading elements, for the velocity range �=0.04-0.12 in the context of TEM-like ?/4 and ?/2 structures with multiple loading elements. A simple transmission lines model is presented and the results of Micro Wave Studio and simulations are discussed. The column of the multistub structures opens the opportunity to minimize current in locations allowing the exploitation of demountable joints and control the frequency splitting between the accelerating and other modes. These resonators are appropriate for the upgrade of the medium- and high-velocity sections of the ANU Heavy-Ion Accelerator Facility. Because of the broad velocity range for which such structures can be tailored, they can also be used in spallation neutron sources and rare isotope accelerators. � 2006 The American Physical Society.
