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
