Wake field suppression

Criterium: losses < 10 W (time domain, or any resonant mode)

Conclusions:

1) complete VD with/without strip shielding

“deep” cavities require strip shielding

2) reduced VD model (no strip shielding)

a) position open/closed

requires shielding on sides of enclosures

b) reduce cavity depth

ok for depth of < 20 mm

c) various designs

ok, analog to b)
