SIMULATIONS OF THE BEAM PERFORMANCE IN THE MAX-II ELECTRON STORAGE-RING

The beam performance of the MAX II storage ring is described by comput er simulations. The dynamic aperture reduction due to chromaticity cor recting multipoles, higher order multipoles in quadrupoles and dipoles , alignment errors and energy deviations is calculated. The future ope ration of the storage ring with insertion devices is discussed. The re sults show that the MAX II storage ring will operate with a reasonable closed orbit deviation and dynamic aperture even without making use o f the correlation magnets in the machine. This implies that the start up procedure would be fairly easy.
