!Start circuit definition
!
! We start with a capacitor and switch with the parameters based on the
! 80 nF version of the GA 35426M Capacitor. C = 40 nF, L = 15 nH , ESR = 0.13 
! We will use a total inductance (demonstrated) of 160 nH for the brick.
! that includes the inductance of the feeds leading to the load and the
! inductance of the load.
!
! The charge voltage will be 85 kV X2. This is the projected normal operating
! point for Z15.
!
! The cavity will have 22 bricks and all of the parameters of the brick model are
! scaled by 22X.
!
! The parallel core loss is calculated at 115.6 .
