Gary -

The operation is continuous as with a typical TC. Refer to my reply to Dr.
Resonance.

Since John is asking about Joules, this implies he is talking about
single-shot operation.  While this may be useful for quantifying
efficiency in that mode of operation, single-shot operation is not
something most of us are equipped to do.  A DC power supply is needed.

Perhaps we can all supply John with some data from each of our coils and
he
could do a tabulation and find an average or statistical value.
