Longitudinal impedance well above the PSB beam spectrum
Longitudinal impedance well above the PSB beam spectrum
Transverse impedance well above the PSB beam spectrum
Transverse impedance The effective vertical impedance for 1 pumping port is expected to be well below 0.01% of the total PSB broadband impedance
Summary Obviously, a proper shielding can only be beneficial in terms of impedance, although no special issues from the beam coupling impedance point of view are expected even without shielding.
