With the use of Ion Storage and Cooler Ring, S-LSR at ICR, Kyoto University, Mg ion beam with 40 keV has been laser cooled not only in the longitudinal direction but also in the horizontal direction by "Synchro-Betatron Coupling". Laser cooling is now tried to be extended to vertical direction with horizontal and vertical coupling with the use of a solenoid magnetic field. At S-LSR, an electron beam cooling is also applied for 7MeV proton beam, resulting an ordered state. Electron beam cooling is also applied for rf captured bunched beam and a short pulse proton beam with the duration of ~3 ns is fast extracted in order to enable beam irradiation. A beam course is now being constructed to irradiate bio-molecular cells vertically from the bottom through a thin film separating the accelerator vacuum from the cultivating liquid containing the cells in the air.
