Hallo friends.
As the situation is, spark gaps are a 'need' in our research work. I am looking for simple materials easy to find for making a static spark gap working endlessly without problems. I want something that can handle all the heat with only help of an air blower. My copper pipe electrodes seems to work well with the help of the blower, but i am sure that there are more materials that can handle more power without melting the metals. Do you have something to propose? Any help would be appreciated.

Tungsten metal with Spherical points - Tesla said this.
I'd almost swear I dated a girl with those...oh, THOSE spark gaps.
Mscoffman thank you. I wonder where someone can find such a material. Do you know if it is a hard or soft metal ? Is there any device or something where I could find it?
Capzro ;D ;D

Try this solid state tesla coil if you have a problem in spark gap :)
The problem starts when you need hv and high current together. I have tried in the past cascading mosfets but over some 2000v I had some problems like explosions :D
I really hate spark gaps. What about this gas discharge tubes of Don's? I think i have to reconsider the more mosfets solution.
On the other hand, spark gap is raw power. You can feel it to your bone!

Try IGBT i know it can handle high voltage, high current and it has fast switching speed. You can use the second picture for teslacoil circuit and replace the transistor with IGBT :)
Igbt is partially a good solution but again it is not as when a gap is firing! By the way, both of your attached images have mistakes. But as an idea is fine and very common in SSTCs. Thanks
