TSG with DC?

List engineers,

Can any of you provide ideas for using a TSG with a pure DC (i.e. filtered)
power supply?  Specifically, I need ideas on how to prevent a power arc when
the TSG fires.  That is, some method which transfers almost all of the DC
supply energy to the MMC, not to the TSG.

I can only think of two ways:  1) have a tremendous blast of air through the
gap to "blow out" the power arc - so it functions something like a RSG at
high speed, or 2) Have a DC supply which "folds back" when the spark gap
fires to prevent a power arc.  I think Marco Denicolai's supply functioned
that way.

In the meantime, I shall try unfiltered DC supplies such as a MOT circuit
which offsets the HV sine wave so it goes to zero each cycle.  The only
problem with that is the BPS can only be 60 which doesn't transfer much
average power to the tank circuit.
