2.1.5 Purely inductive

There are several devices which are described as purely inductive impedances; their impedance is given by

. The

for these devices are given in Tab. 3.

**Table 3:** Parameters for devices described by an inductance. The impedance for the septum cavities is computed by taking the of 32 m given in [4] and scaling it by 2R/b², taking b to be 5 cm, the radius of the drift tube [4]. The -function at the septum cavities is from [5].

Accelerating cavities (total for 8)	3.8 k	150 m
Feedback (Septum) cavities (total for 3)	108 k	200 m
