ION-BEAM CRYSTALLIZATION IN CRYRING-MSI HEAVY-ION STORAGE-RING

The investigation on ion beam crystallization in a realistic heavy ion storage ring, the CRYRING at MSI, was carried out by means of molecular dynamics simulations. All the quadruple and dipole magnetic fields were included. The CRYRING lattice design parameters such as tunes and emittances were reproduced correctly in the simulation. It was found that, at the normal working point of CRYRING, 1D ordered chains can be formed in systems of about 10(5) ions at low temperatures and 3D crystalline structures can be obtained in systems of about 10(7) ions at low temperatures accompanied by continuously cooling. In this paper, we concentrate on formation and detection of ID ordering in Li-7+ and Ar-40(18+) ion beams in CRYRING.
