| Abstract |
The ReAccelerator ReA3 is a worldwide unique, state-of-the-art linear accelerator for rare isotope beams. Beams of rare isotopes are produced and separated in-flight at the NSCL Coupled Cyclotron Facility and subsequently stopped in a linear gas cell. The rare isotopes are then continuously extracted as 1+ ions and transported into a beam cooler and buncher. Ion pulses provided by this device are then transported to a charge breeder based on an Electron Beam Ion Trap (EBIT) where they are captured in flight. The 1+ ions are ionized to a charge state suitable for acceleration in the superconducting radiofrequency (SRF) ReA3 linac, extracted in a pulsed mode and mass analyzed. The extracted beam is pre-bunched before injection into the RFQ and SRF linac, both operating at frequency of 80.5 MHz, and then accelerated to energies from 300 keV/u up to 6 MeV/u, depending on the charge-to-mass ratio of the ion. Stable isotopes can alternatively also be injected into the linac from the EBIT in off-line mode (by ionization of residual gas) or from external off-line ion sources. This contribution will focus on the methodology, properties and techniques used to accelerate and control low intensity rare isotope beams. Results obtained during the preparation of various experiments using the ReA facility, including those with the rare ions 46Ar and 37,46,47K will also be presented.
