The split-loop resonator as a superconducting heavy ion accelerating element

The Cern Heavy Ion Accelerating Facility

CERN’s Lead Ion Accelerating Facility has been operating successfully for its first physics run. The facility, supported financially by some member states and designed, built and installed in a collaboration with several other laboratories (not only from member states), features a completely new linac and a major up-grade of the existing CERN machines. This paper reviews the design philosophy a...

Design Study of a Superconducting Cyclotron for Heavy Ion Therapy

A cw Heavy Ion Linac Based on Superconducting CH-Structures

According to the Unilac upgrade program for the SHE research at GSI, a new high energy part of the High Charge State Injector (HLI) has to be worked out. One of the versions of this linac foresees the acceleration of the highly stripped ions with charge-to-mass ratio of 1/6 delivered from the existing HLI at 1.4 MeV/u. The output beam energy should allow experiments at the Coulomb barrier and i...

A Superconducting Solenoid for Heavy Ion Beam Focusing

A 6 T superconducting solenoid has been constructed to focus heavy ion beams on the production target of radio isotope beams. The design field on axis is 6.2 T with an average current density of 9,600 A/cm. The overall coil length is 1.1 meter, and the coil is divided into three equal-length sections to ease winding and to reduce IR drop through diode connection. A main feature of the system is...

Tesla Superconducting Accelerating Structures

The application of the superconductivity phenomenon in accelerators originated with pioneer work in the late sixties at the High Energy Physics Laboratory (HEPL) at Stanford University [1]. Starting with the deposition of lead on copper and niobium on copper, by the end of 1968 the HEPL group had developed and tested the first bulk niobium superconducting accelerating cavity [2]. The result was...
