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.
