Magnetic high current ion storage ring

A novel magnetic storage ring for an accumulation of low energy (W ~ 100 keV-1 MeV) high current (~10 A) proton beams is under investigation at Frankfurt University. It offers various possibilities for example to investigate the (p+B¹¹) fusion reaction under different non-neutral plasma state conditions. The proposed ring structure based on a toroidal magnetic field possesses different potential concepts for space charge compensation, accumulation of intense proton beams, and colliding beam operation. The beam life time, reaction cross sections, reaction products from interaction with gas jet and ring operation should be studied in a stellarator-type storage ring for the first time. The theory of thermal and non-neutral plasma confinement on magnetic surfaces is translated to numerical simulations on circulating ion beams. The stability conditions, space charge effects and constraints of the numerical model are studied and will be presented. An additional experimental setup consisting of two 30deg toroidal segments and ion sources is suited to study the nontrivial beam injection into such a ring configuration.
