Production of Radioactive Isotope Beams with In-Flight Fragment Separator BigRIPS

Abstract

The BigRIPS fragment separator is the core experimental device at RIKEN RIBF and used to produce a large variety of radioactive isotope beams based on the in-flight separation technique. A total of 1460 isotopes have thus far been produced for 184 experimental programs using in-flight fission of a uranium beam as well as projectile fragmentation of stable beams since it became operational in March 2007. The number of new isotopes produced and identified at BigRIPS has reached 142 for about 13 years of operation. Research and development activities for more efficient production of high-intensity and more exotic RI beams have been launched.
