The transition energy, γ t, of a heavy-ion storage ring is an important machine parameter.The variation of γ t versus the magnetic rigidity, B ρ, over the acceptance of the ring directly affects the mass resolving power achievable in the high-precision isochronous mass spectrometry (IMS). (IMS).

For the MAX IV 3 GeV storage ring this amounts to five free parameters. Along with these parameters come a set of obvious boundary constraints: J x > 0, J δ > 0, and beta functions exist. Initially we distinguish between solutions providing β x ∗ > 4 . 5 m, i.e. at the center of the long straight (in the vicinity of the injection septum) and those that
SMES is an advanced energy storage technology that, at the highest level, stores energy similarly to a battery. External power charges the SMES system where it will be stored; when needed, that same power can be discharged and used externally. However, SMES systems store electrical energy in the form of a magnetic field via the
In the initial design [1] of the DBA lattice, it is a high- beta lattice with high βx(15m) in the middle of all straight sections, and the circumference of the storage ring is 384 meter. To obtain high flux density, low β in some of the. x. straight sections is required. Therefore the storage ring magnet lattice has been adjusted to be able
