Current-step technique to enhance plasma focus compression and neutron yield
A current-step technique is applied to the plasma focus by modifying the Lee Model code, incorpo- rating a current-step bank to add current to the focus pinch at the time of the current dip. For a 50 kV, 1 MJ, 6 ls rise- time bank, the current-step from a 200 kV, 0.4 MJ, 0.8 ls rise-time bank m...

Summary: | A current-step technique is applied to the
plasma focus by modifying the Lee Model code, incorpo-
rating a current-step bank to add current to the focus pinch
at the time of the current dip. For a 50 kV, 1 MJ, 6 ls rise-
time bank, the current-step from a 200 kV, 0.4 MJ, 0.8 ls
rise-time bank maintains the pinch current at 2.2 MA,
enhances compression by 1.9 and increases the neutron
yield from 2.5 9 10 12 to 1.03 9 10 13 . The increase is
attributed mainly to the step nature of the current which
favorably shifts the end-point of compression; rather than
to the scaling in terms of energy or current. |
