A High Gradient Superconducting Quadrupole for a Low Charge State Ion Linac
نویسندگان
چکیده
A superconducting quadrupole magnet has been designed for use as the focusing element in a low charge state linac proposed at Argonne. The expected field gradient is 350 T/m at an operating current of 53 A, and the bore diameter is 3 cm. The use of rare earth material holmium for pole tips provides about 10 % more gradient than iron pole tips. The design and the status of construction of a prototype singlet magnet is described.

A Low-charge-state Injector Linac for Atlas
The design of a low-charge-state linac which is capable of accelerating, for example, Sn for injection into the existing heavy-ion linac ATLAS is discussed. The injector linac is intended for radioactive beam applications, and will accelerate a low-charge-state beam to energies of 500 keV/nucleon, at which point the ions can be stripped to charge states sufficiently high to be injected into ATL...

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...
