[TCML] Re Electrode diameter

[Phillip Strauss <pstrauss1947@xxxxxxxxx>]

Hi All,
I'm building a 12" diam. secondary SRSG coil running at 10Kv, 7KVa,  
50Hz and 100bps. Motor speed is 3000rpm, rotor 12" diam G10, two  
flying electrodes at 11" diameter and tank capacitance 0.15uF.,
I have a selection of Tungsten electrodes, both 1/4" and 1/2" diam  
and have a choice of either two or four fixed gaps in heavy brass. Is  
1/4" diam adequate to contain the heat
or is 1/2" better perhaps to aid regular firing albeit increasing the  
dwell. Should the electrode gaps be minimal ( without risk of contact  
of course) or is there  an optimum distance,
again to slightly reduce the dwell time. I appreciate that the  
relatively low input voltage limits experimentation in this last regard,
Any help greatly appreciated,
Regards,
Phillip.
