Present status of RILAC

This year is the 40th year since the RIKEN heavy ion linac (RILAC) started to supply ion beams for experiments in 1981. Since then, the RILAC has been supplying various ion beams for various experiments. Research experiments on the heaviest elements have been carried out since 2002 at the e3 beam course of the No.1 target room of RILAC. For the nuclear experiments of the RI Beam Factory (RIBF), ion beams accelerated by the RILAC were injected into the RIKEN Ring Cyclotron (RRC). A new 28-GHz superconducting electron cyclotron resonance ion source (28-GHz SCECRIS) and a new superconducting linac (SRILAC) were commissioned. The present status of the RILAC operation is reported. (author)
