PRODUCTION, TRANSFER AND INJECTION OF CHARGED-PARTICLES IN TRAPS AND STORAGE-RINGS

The potential of electromagnetic traps and storage rings for precision measurements in atomic and nuclear physics is greatly enhanced by combining the features of both, particularly when external sources of exotic ions can also be used. Such applications require the transfer of collections of ions between these devices. The basic engineering principles for designing such transfer are presented in terms of projections of the B-dimensional phase space volume of charged particle collections into momentum-displacement action planes. The significance of such projections is discussed as well as some of the general features of computational methods to obtain such projections from numerical simulations of charged particle motions within and between the devices. Some examples of the use of the design methods are presented.
