Description
The complete characterization of high-energy Radioactive Ion Beams delivered to experimental stations is essential to the analysis of the phenomenology studied. This includes insights at the purity of the beam as well as its geometrical properties in the transverse and longitudinal phase spaces. The difficulty resides in adapting experimental techniques to very low-intensity ion beams typically encountered (below 10E6 pps).
As a new electron gun was recently installed at REX-Electron Beam Ion Source, the general performances of the charge-breeder were re-evaluated and an attempt is being made to correlate experimentally probed mechanisms with simulations. Besides, a new method is presented for measuring spectra of contaminants produced by REXEBIS with single-ion detection capability. After post-acceleration, we demonstrate the aptitude to measure the transverse and longitudinal beam properties, still in the sub-femto ampere range, and to manipulate the density distributions in the trace space.
