Re: Really big VTTCs--Part II
Original poster: Sparktron01@xxxxxxxxxxx
Below is an excellent article on a 50kW push-pull colpitts oscillator
for 3.0MV accelerator that is on
Hot-streamer. The output transformer (think Tesla resonator
secondary) is in an oil filled tank.
I think Terry may have saved this article for us (and posterity... :^D )
A mistake in schematic as shown is a (+) jumper is missing from upper
RFCp to lower RFCp. Or
alternatively use only one Cft, and still connect both RFCp's in
parallel with (+) output of 10kV DC
power supply (+ is upper line out of HVPS block as drawn).
Note the modular construction of the panel, and each "tube deck" is
identical for ease of repair
and maintenance. Also read North's high power microwave transmitter
book on Jim Lux's site,
paying particular attention to maintainability section.
This system is about 95% there for a high power VTTC, at least in
construction and mechanical
