	One other thing from that chapter, which has been on my book shelf
since it was originally published.  They mention trying RSG's from
"radio transmitters" and say they don't work any better than their
design using small diameter electrodes.Of course, in those days few
radar pulsers has an output of more than a couple of kW average. The
design of the gaps in question went to extreme lengths to maximize gap
area (wide ribbons, etc.).  One of the purposes was to improve
quenching.
