Hi All,

There is a BIG problem with a gap quenched magnetically with the primary
coil's current.  At the point you want to quench the gap, the secondary has
all the energy and the primary current is near the zero point.  Thus, just
when you need the maximum current to get the maxiumum field to blow the gap
out, The current is zero...  Sorry bout that :-)

Cheers,

	Terry
