Marco,
   
That is why I am designing it to go up to 5000 Hz. My design is based on the 
assumption of 30 oscillation cycles per bang.  The TC frequency was designed 
such that I should be able to "catch the tail" at 4000Hz charging freq.  If 
necessary I can use a cap up to about 7 nF(30kV) with what I have on hand, 
although the impedance match becomes important at the higher charging rates, 
if I am not mistaken.  I suppose if 5000Hz is insufficient, I could alter the 
timing circuit.  The transformers I am using would actually work better above 
5000 Hz(originally used at 20kHz).   I could also play with the voltage a 
lot.  I plan on 10kV out from the trannies, but they will withstand up to 
60kV. I will limit this to 30kV as more would make the corona problems 
significant(max available capacitance would be 3.5 nF at this voltage to 
ensure safety of my caps).  The  power output can be as much as 4800W(60kV -at- 
80ma was the original output of the X-ray power suppy I removed the trannies 
from) but I plan to keep it to about 1800W at this stage.  As you can see, 
there is much flexibility in my set up.  I am just starting it and may make a 
number of changes as it progresses, but am planning to make it adaptable to 
improve the chances of success.    
Any other comments or imput welcome,
Mike
