Abstract :
The reaccelerator system under development at the National Superconducting Cyclotron Laboratory (NSCL) will consist of a helium gas Radioactive Ion Beam (RIB) stopper, an electron beam ion trap, a cw radio frequency quadrupole (RFQ), and a superconducting linac to accelerate RIBs up to 3 MeV/u with charge-to-mass ratios (Q/A) of 0.2 - 0.4. The RFQ will operate in cw mode at a frequency of 80.5MHz to accelerate RIBs from 12 keV/u to 600 keV/u. An external multi-harmonic buncher will be used to achieve a small longitudinal emittance beam out of the RFQ. In this paper, we describe the design of the RFQ and the result of beam dynamics simulation.
