[TCML] CW magnifier

[Carl Noggle]

Hey, Carlos,

Any type of Tesla coil can work CW.  There is no electrical difference 
between a magnifier and a regular TC.  However, you would have to drive 
it with a solid state or tube type driver, since there is no way to 
quench a spark gap fast enough to achieve a rep rate of 100 or 200 KHz.  
If you can figure out how to do that, you would be able to buy as many 
Tesla coils as you want.  For a small or medium sized coil, I would 
recommend a half- or full-bridge driver made with FETs. The bridge 
circuit protects the FETs from spikes and is very robust.  From personal 
experience, at these frequencies it is necessary to make sure that the 
connection between the driver and the gate is VERY low inductance.  
Also, there must be a short dead time between the phase one and phase 
two clocks to avoid shorting the power supply through the FETs.

It would be very cool to see what such a TC would do.
