Cavity Sensitivity Estimates

Position Cavity

The dipole mode sensitivity was estimated from the following formula, the measured external quality factor of 617 and R/Q from simulation in several codes, of which CST and GdfidL use a hexahedral mesh while Ace3p uses a tetrahedral mesh:

Code R/Q /Ω Sensitivity/V nC-1 mm-1
GdfidL 0.85 8.7
Ace3p 0.77 8.3
CST 0.77 8.3

Reference Cavity

The measured external quality factor of the reference cavity is 203.

Code R/Q /Ω Sensitivity/V nC-1
GdfidL 28.2 87
Ace3p 9.8 52
CST 10 52
