Abstract / Description:At ICR, Kyoto University, an ion accumulation and cooler ring, S-LSR has been constructed. Its meam radius and maximum magnetic rigidity are 3.6 m and 1.0 Tm, respectively. 24Mg+ ions with the kinetic energy of 35 keV are to be laser-cooled by the frequency doubled ring dye laser with the wavelength of 280 nm. In order to avoid the shear heating, dispersion compensation is planned by the overlap of the electric field with the dipole magnetic field in all 6 deflection elements. Intermediate electrodes, which can be potential adjusted, are to be utilized so as to realize a uniform electric field in a rather limitted vertical gap, 70 mm, of the dipole magnet. Synchro-betatron coupling needed for 3-dimensional laser cooling is to be realized by controlling the dispersion of the lattice. The possibility of realizing tapered laser cooling with use of an Wien Filter combined with the laser cooling is also being investigated. In the present paper, status of construction of S-LSR are to be presented together with the preliminary result of beam simulation assuming dispersion suppressed lattice.
