Abstract
The ReA re-accelerator of the National Superconducting Cyclotron Laboratory at Michigan State University utilizes an Electron Beam Ion Trap (EBIT) for charge breeding thermalized rare isotope beams. Recent commissioning measurements have been performed to characterize the performance of this EBIT. The energy spread of extracted highly charged ion beams was measured to be about 0.3% of the total beam energy. From this, the temperature of the ion ensemble in the trap is calculated to be kTq/q = 31 eV for O7+, while it is kTq/q = 25eV for K15+. In addition initial results are presented for two extraction schemes developed to spread highly charged ion pulses in time. [ABSTRACT FROM AUTHOR]
