Superconducting RF cavity for high-current cyclotrons Conference Paper uri icon

abstract

  • A novel superconducting cavity is presented for use in high-current cyclotrons. Thecavity is an extrusion of a 2- D double-quarter-wave structure, in which the ends of theextrusion are wrapped around and joined so that the cavity has no end perturbations. Poweris applied via a linear array of input coupling loops, so that an rf sheet current islaunched in a laminar flow that matches the distribution of power coupled to the orbits.Each loop is driven by an independent solid-state rf source. A strategy is presented forusing to advantage the independent control of phase and amplitude of the drive array tosuppress transient phenomena. Longitudinal modes can be strongly suppressed. Theseprovisions are of importance to suppress rf phenomena that can limit beam current.Copyright 2012 by IEEE.
