So I know it's generally not a good idea, but I wondered what actually is the limiting factor. Does the magnetron heat up much more quickly? - and if so what's the physics going on that's causing it to heat up - is it increased current in the resonant cavities ? Also is it bad for the cathode ? Is there increased back bombardment etc ?
I've always assumed the glass turntable absorbs some microwaves in case it is run empty.
Is this the usual cause of the antenna cap arcing - and is that just because of the very high voltage it gets to ? I've noticed that high power magnetrons don't have a metal cap at all they are all ceramic.
