Sparker discharge begins the show, 3 torr pressure in air, loaded with flour and graphite powder
|
|

After sparker discharge is over (drat, will be simultaneous later) microwave breakdown starts at base of antennas
|

![](small/4%20e%20s&m%203%20torr1.jpg) |
End of discharge, dying away; starts and ends at base of antennas
|

New arrangement of wiring and power distribution; see big new resistors (small older ones blew up), 500 ohms distribute current pulse among magnetrons; variac adjusts power to magnetron filaments (3VAC after another transformer)
