!   *********   Thor - 4-drive-circuit model   *****************************************************
!
!    The following model of Thor uses 4 drive circuits to model Thor's 200 LTD bricks.
!    Hence the model combines 50 bricks into one drive circuit.
!
!    The 4 circuits are fired at different times to achieve a 200-ns current-pulse rise time.
!
!    The first of the four drive circuits:
!    We assume each LTD brick has a capacitance of 20 nF:
!
RCG  1.000E12    1.0E-6
!
!    We assume each cavity is charged to +/-100 kV.
!
INITIAL    VC1   2.0e5
!
!    We assume each brick has a resistance of 0.37 ohms, and an inductance of 185 nH.
