An electron beam ion trap for the NSCL reaccelerator

The reacceleration of stopped fast-fragment beams or low-energy ISOL beams to the energy range of 0.3-12 MeV/nucleon allows for experiments such as low-energy Coulomb excitation and transfer reaction studies and for the precise study of astrophysical reactions. The coupling of a reaccelerator to a gas stopper at a fragmentation facility will provide rare isotope beams of nuclides not available at ISOL facilities in this energy regime. The implementation of charge breeding is a key to obtain a compact and cost-efficient reaccelerator and it is foreseen in the development of a reaccelerator at the NSCL at MSU. An Electron Beam Ion Trap (EBIT) will be used for charge-breeding as it has the potential to rapidly and efficiently output highly charged ions in a single charge state. The system will provide highly charged ions at an energy of 12 keV/nucleon to a compact linear accelerator for further acceleration. (c) 2008 Elsevier B.V. All rights reserved.
