Superconducting Heavy-Ion Linacs

Performances of the ISAC Heavy Ion Linacs

ISAC is the TRIUMF facility for the production and post acceleration of Rare Isotope Beams (RIBs). The post acceleration section includes two normal conducting linacs, an RFQ injector and a variable energy IH-DTL, and a superconducting linac composed of five cryomodules each containing four quarter wave bulk niobium resonators. All three machines operate CW. The RFQ and DTL deliver beam since 2...

Beam loss studies in high-intensity heavy-ion linacs

090101-1 The proposed Rare Isotope Accelerator (RIA) Facility, an innovative exotic-beam facility for the production of high-quality beams of short-lived isotopes, consists of a fully superconducting 1.4 GV driver linac and a 140 MV postaccelerator. To produce sufficient intensities of secondary beams the driver linac will provide 400 kW primary beams of any ion from hydrogen to uranium. Becaus...

Development of Superconducting Quadrupoles for Heavy Ion Fusion

Multi-beam heavy-ion accelerators are considered as promising drivers for inertial fusion energy. The High Current Experiment (HCX) at Lawrence Berkeley National Laboratory (LBNL) will test driver-scale beam dynamics in a single transport channel. Single bore, NbTi superconducting quadrupoles are being developed for the HCX, taking into account their possible use as modules in a quadrupole arra...

Conceptual Design of Superconducting Quadrupole Arrays for Heavy-ion Fusion

Extensive studies have been performed to optimize the design of superconducting quadrupole arrays for beam transport in future heavy-ion fusion accelerators. In these arrays 20 or more quadrupole coils are densely packed with their axes aligned in parallel. Field strengths between 3 and 5 tesla at the inner coil diameters have been investigated. The aperture of the individual quadrupoles has be...
