 note = {S-LSR is a compact ion storage and cooler ring for R&D of the accelerator for the medical treatment. The vacuum system for S-LSR has been operated from September 2005. The study of the vacuum and the beam lifetime for the proton beam and Mg beam are presented. The design vacuum pressure in S-LSR is 3x10-9 Pa. But the measured
vacuum pressure is about 7x10-9 Pa because a vacuum leak trouble had happened while lowering the temperature of the baking. The lifetime of 7MeV proton and 35keV Mg+ beam are measured about 55000sec and 13sec in the present status. They are almost consistent with the calculation.},
