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

2. Longitudinal impedance from an ideal shielding  Z/n~ 8 10 -6 Ohm  To be checked: how many? How many other designs? Compute transverse impedance

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

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

5. Eigenmode solver ModeFreqRQ 11.6~04400 22.5~05600 334.54600 43.4~05100  No harmful longitudinal mode detected
