Superconducting Radio-Isotope Beam Separator BigRIPS at RIKEN

Abstract

BigRIPS fragment separator is the in-flight fragment separator with the large acceptance and the high momentum resolution that consists of 42 superconducting quadrupole magnets and 6 room-temperature dipole magnets. It is the core experimental equipment of RI beam factory (RIBF) at RIKEN and used to produce a wide variety of RI beams through the fragmentation of stable beams as well as the in-flight fission of the uranium beam. The BigRIPS fragment separator started in operation in 2007 and since then, 145 kinds of RI beams have been produced and used in physics experiments. 47 new isotopes were discovered by using the BigRIPS fragment separator.
