CRYSTAL: a storage ring for crystalline beams and other applications

The possibility of generating crystallized ion beams has always excited the interest of most people working on particle accelerators. The reason of this interest has manifold aspects: either a knowledge on a completely new research field or some of the applicative potentialities, connected with crystallinebeams, would justify a careful investigation on this content. The Conceptual Design of a low-energy heavy-ion storagering, called CRYSTAL, proposed for the experimental demonstration of crystallinebeams at Legnaro Laboratories is presented. Besides the study of crystallinebeams the CRYSTAL StorageRing (CSR) offers a large potential for fundamental research in nuclear, atomic and molecular physics. In this sense, the development of a second generation cooler ring with better lattice will give large possibilities to investigate more deeply in fundamental Physics

A storage ring for crystalline beam studies

The possibility of generating crystallized ion beams, i.e. beams whose particles are located at fixed positions, has always excited the interest of most people working on particle accelerators. The reason of this interest has many aspects: knowledge either of a completely new research field or of some of the applicative potentialities, connected with crystalline beams, would justify a careful investigation of this subject. After the successful exploitation of electron cooling in several heavy ion storage rings the possibility of generating crystalline ion beams became more realistic. New cooling methods, like laser cooling, give a further opportunity to reach an ultracold system of particles necessary for the state transition to the crystalline configuration. The conceptual design of a low-energy heavy-ion storage ring, called CRYSTAL, proposed for the experimental demonstration of crystalline beams at Legnaro Laboratories is presented. The physics of crystalline beams as well as the main criteria to design a storage ring suitable to crystallize ion beams are discussed. The effects of instabilities for space charge dominated beams, shear forces in dipole magnets and lattice periodicity breaking are also discussed in detail
