Minimization of Beam Emittance Wen Wei Ho Mentor: Chun-xi Wang
Rationale and Physics Low emittance is desired since: ● Greater brilliance of light from synchrotron radiation ● Preserves beam quality in arcs of energy-recovery linac- based light sources ● Greater luminosity Physics behind emittance: ● Radiation damping ● Quantum excitation
Work done so far ● Equations reduce to: ● ● Optimization of the bending profile, ρ(s)
Work done, work in progress, and work to be done ● Have obtained analytical expressions for minimal emittance for optimal profile (symmetric linear-flat-linear profile) ● Have obtained analytical expressions for the case of an undulator ● In the process of refining theory ● To consider the case of asymmetric profiles ● To attempt a variational method as another approach to the optimization problem

Injection mismatch type of injection mismatch will lead to an emittance blow-up. Off axis

Injection mismatch: As a rule, proton/ion accelerators need their full aperture at injection, thus avoiding mismatch allows a beam of larger normalized emittance * and containing more Protons. In proton/ion ring accelerators any Injection
