Abstract :
A new compact ion cooler ring (S-LSR) in Kyoto University has a circumference of 22.197 m and maximum magnetic rigidity of 1 T/m. One of the research subjects of S-LSR is a test bed to produce crystalline beams. Ring optics is designed to satisfy several required conditions for the beam ordering such as a small betatron phase advance and small magnetic error. We plan two cooling approaches. One is an electron beam cooling with 7 MeV proton beam from a linac. This target is 1-dimensional Coulomb strings. The beam-ordering simulation is carried out using the S-LSR parameters. The other is laser cooling with 35 keV Mg+ beam from an ion source. The goal of the laser cooling experiment is to produce two-dimensional and three-dimensional crystals.
