Six-dimensional approach to the beam dynamics in HIDIF scenario

In the HIDIF scenario the accumulation of the required total number of heavy ions (2–3×1015 per ring) is an important issue. However nonlinear magnetic fields can lead to emittance growth and beam losses if the tunes qx and qy satisfy usual the resonance condition, as a result of the space-charge tune depression. The transfer map technique is the usual approach suitable to include lattice nonlinearities in the transverse single-particle dynamics. An extension of the transfer map concept to six dimension is presented. Space-charge, lattice nonlinearities and longitudinal electric fields are included by a kick approximation technique. A first application to the HIDIF scenario in a debunching process is presented.
