RE: Sold state IGBT disruptive coil spark gap idea

As one who's never toyed with DRSSTC's, I have a dumb question that's
probably been discussed previously, but -

What is the performance-consequence to completely eliminating the
concept of quench, and permitting as many pri-sec trades as it wants?
