[TCML] Twin Coil Prototype at Maker Faire

[Greg Leyh]

Hi Terry,

They're fairly straightforward coils, secondary form is 24"x105", toroid 
is 11"x55".  These dimensions are 1:12 scale of the 12-story NLL design. 
  These prototype coils are used mainly to test design concepts for the 
NLL coils.  The primary drive is the conventional C-switch-L scheme, 
with IGBT's in place of a spark gap for improved efficiency and control. 
  The primary operates at 3kV, 4.5kA.  Currently, the system can produce 
an 18ft point-to-point arc with about 6kW input power.  Although the 
prototype operates from either single or three-phase power for 
convenience of demonstration, the final NLL design will use a dedicated 
six-phase, 20kV system.   GL
