Presentation transcript:

Longitudinal impedance of new RF fingers O. Berrig, C. Garion, B. Salvant

Longitudinal impedance from an ideal shielding  Z/n~ Ohm  To be checked: how many? How many other designs? Compute transverse impedance

Longitudinal impedance from bellow with shielding thin shielding difficult to mesh correctly with CST wakefield

Comparing longitudinal impedance  Very similar Z/n : shielding is working well in longitudinal

Eigenmode solver ModeFreqRQ 11.6~ ~ ~05100  No harmful longitudinal mode detected
