A next generation slow radioactive nuclear ion beam facility (SLOWRI) which provides slow, high-purity and small emittance ion beams of all elements has been proposed as one of the major experimental facilities at the RIKEN RI-beam factory. High energy radioactive ion beams from the projectile fragment separator BigRIPS are thermalized in a large gas catcher cell, guided and extracted to vacuum by a combination of DC electric fields and in-homogeneous RF fields in the cell (RF ion guide). In experiments conducted so far, an overall efficiency of 5% was achieved for ≈ 100A MeV ^8Li ion beam from the present projectile fragment separator RIPS and the dependence of the efficiency on the beam intensity was investigated. Possible methods to improve the performance of the RF ion guide scheme as well as planned experiments at SLOWRI are discussed.
