Description
A novel storage ring is proposed in which the bunch maintains a fixed orientation relative to the outside world (does not rotate with the ring as usual). In this geometry, magnetic focussing can confine all three dimensions of the bunch without RF. The application of this ring to ultra-low emittance Coulomb crystals is investigated, where the focussing force balances the space charge to give zero phase advance and the crystal structure can be preserved for tens of milliseconds. The dynamics is highly coupled and dominated by weak focussing. Some different instabilities are observed, one of which appears to be suppressed by adding nonlinear components to the ring field.
