Subject: RE: [TSSP] Secondary dynamic Efield
Hi Bert,
I'm using just distilled water and copper electrodes. Tin-lead plumbing
(a few square mm). Massive use of epoxy. After four weeks no deposits
yet appeared in my prototype.
The TC toroid has always got it's 25 mm o.d. stainless ball to increase
locally the E-field and initiate discharges.
I would be already satisfied with 100 ns. That would make a 3.5 MHz
bandwidth :)
Best Regards
