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.

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
