An Injector for a Multi Ion Beam Driver Linac
نویسندگان
چکیده
An advanced facility for the production of exotic shortlived isotopes far from stability (RIA) could use as the driver a high power cw superconducting linac [1]. Due to the wide range of particle velocities ( =0:019-0:81), different cavity types are required. This paper describes a possible design for the injector portion (up to =0:1) of the driver linac. The proposed injector design consists of a multi-harmonic buncher, an RFQ (f=57.5 MHz), 4-gap fork resonators (f=57.5 MHz), and finally, 2-gap quarter wave resonators (f=86.25 Mhz). The results of numerical simulations and a comparison different possible RFQ designs (4-vane, IH) are presented.

Ion Sources and Injectors for Hif Induction Linacs
For heavy ion fusion (HIF) induction linac drivers, a typical injector requires total beam current of 50-100 A and is comprised of many individual beams of 0.5-1.0 A each. As a step towards developing a full ion driver for inertial fusion energy (IFE) power plants, an Integrated Research Experiment (IRE) will be proposed within a few years [1]. The IRE will have a linac of more than 150 MeV and...
متن کاملAnalysis of a Multi-spoke Option for the Ria Driver Linac*
Beam dynamics simulations of the proposed Rare Isotope Accelerator (RIA) [1] driver linac have been done. The RIA driver linac is designed to accelerate stable ion beams from proton to uranium to final energies of 400 MeV/u for the heaviest and about 900 MeV/u for the lightest ions with beam powers of 100 to 400 kW. Two stripping sections are used to increase the charge state of heavy ions and ...
متن کاملA 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...
متن کاملChallenges to the Fermilab Linac and Booster Accelerators*
A report on the challenges confronting the Fermilab Linac and Booster accelerators is presented. Plans to face those challenges are discussed. Historically, the Linac/Booster system has served only as an injector for the relatively low repetition rate Main Ring synchrotron. With construction of an 8 GeV target station for the 5 Hz MiniBooNE neutrino beam and requirements for rapid multi-batch i...
متن کاملCOMMISSIONING OF THE 1.4 MeV/u HIGH CURRENT HEAVY ION LINAC AT GSI
The disassembly of the Unilac prestripper linac of the Wideröe type took place at the beginning of 1999. An increase of more than two orders of magnitude in particle number for the most heavy elements in the SIS had to be gained. Since that time the new High Current Injector (HSI) consisting of H-type RFQ and DTLstructures for dual beam operation was installed and successfully commissioned. The...
