Re: [TCML] High Power Static Gaps

[Sfxneon@xxxxxxx]

Thanks Jim, that gets me to wondering, if at some point, pressure  might work 
better than vacuum?
 
Are there any more considerations than just overheating of the electrodes?  I 
know that proper quenching is the real goal and keeping the electrode  
temperature as low as possible is essential for that, but could a single static  gap 
quench at multi-kilowatt power levels if kept cool enough? 
 
Which brings to mind this question: Is there anything like a tungsten flat  
washer available anywhere? If so, how about brazing one on to the face of each  
copper cap electrode?

The literature has references to gaps of this type (generally,  not with 
the specific construction you describe) running at multiple  kilowatt 
power levels.  The Marx blast gap is a good example.  It  actually used 
air blowing out through the center hole in the  electrode.
