Design Examples

As a design example we have chosen a 2-stage magnetic pulse compression network with a gain of 10 delivering 100 ns, 30 kV, 30 J pulsed to a laser load represented by a 67 nF peaking capacitor. Three examples are given (See table, below).

  • Two stages 15µm Metglas® alloy 2605CO
  • One stage each Metglas® alloys 2605CO and 2705M
  • Two stages of 18 µm Metglas® alloy 2705M

Note that the system with the Alloy with the highest B has the least core mass, but the greatest loss. The largest increase in efficiency is achieved by using the lower loss alloy in the final stage.
