Longitudinal impedance from an ideal shielding
Z/n~ 8 10-6 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

1 1.6 ~0 4400
2 2.5 ~0 5600
3 3 4.5 4600
4 3.4 ~0 5100
No harmful longitudinal mode detected
