Current SISG coil work. Anyone care to share their PCB diagram?

Currently interested in building a SISG coil. However when I do the search in this site I get all sorts of dead links.
What is the current status of the SISG based coils. Did the technology ever advance?

I am thinking of a 5-6Kvdc @ 0.6A PSU Double radar-range MOT with doubler.

Thank you.

Call it advance or degrade, in my work, the SISG became the triggered Brisg, and it performs.

WOw, alright now I am really curious!
Do you have a parts list for the BRSIG type 'gap' or a circuit diagram?
because I am planning on making such a SISG type coil running 2 paralleled mots running a voltage doubler (DC).

Doesn't Terry Fritz have some great info on these coils. Couldn't find the link to his website though.

Sl -

Mark Dunn was an early SISG builder, and he's archived lots of SISG design info at:

Any more info (circuit dia) on the triggered BRISG? Looks like from the link (pics) you are using a huge IGBT brick. It is difficult to see what makes up the complete circuit. Correct me if I am wrong, this circuit runs DC, just as the SISGs right?

I am thinking of building a Demo coil here in South Korea. IGBTs are plentiful here and so are CDE caps.

I am hung up building an advanced DRSSTC at the moment,

so I suggest that you dig deeper into the online documentation and develop your own design based on it.
