!Start circuit definition
!
! Rev 1 No Marx switch losses
!
! We start with a Marx capacitance of 100 nF equalling the CPL capacitance.
! We will leave ESR and switch losses for later.
! We will use a total inductance of 350 nH for the Marx and L1. This inductance is needed to 
! get the required rise time of the voltage on the CPL.
! We will terminate the CPL capacitor in a water switch with no losses and have a 0.5  load.
!
! The charge voltage will be 85 kV.
