I think that high rep-rate synchronized operation was used in the early spark gap transmitters to achieve a near-CW mode of operation. It is difficult but possible, but since breakout tends to occur on most of our coils anyway through corona, racing sparks, or conventional streamers, it's not clear that there's much more to be gained. What is it that you're trying to achieve? Regards, Gary Lau MA, USA
Gary's right [subject has been discussed here before as I recall]. This was what Marconi's "timed spark discharger" did - one spark per cycle of RF and one spark gap point ditto.

Have someone on The List, experimented with capacitive discharges from primary to secondary, at such a high rate, and in tight synchronization, so sucessive bangs occur in phase, promoting reactive power increase over time, indefinitely, until spark breaks out, no matter how big and smooth topload is? Why is this not possible? Mechanical systems exhibit this phenomena (Tacoma Bridge).

Don't know if the last one will survive line breaks but it has good photos. Problem of course is doing this at high frequencies................. Ed _______________________________________________ Tesla mailing list Tesla@xxxxxxxxxxxxxx http://www.pupman.com/mailman/listinfo/tesla
