Re: Jan Ruge Fusion Attempt @ Chaos Darmstadt

... My potential x-ray flux would have been of great concern if I hadn't bias my target. Your method is certainly better suited for high voltage safety as long as your vacuum housing near the HV input is well grounded. Your system performance will be better at the lowest possible vacuum - achieving ...

Re: The start towards Fusion

Jess, I commend you on your creativity, but I must admonish you that you created a significant safety hazard. Any glass vacuum chamber carries some risk, but that glass jar is totally unsuited for vacuum use, especially with plasma inside. Even a glass vessel designed ...

Re: What vacuum chamber do I use?

Do you have any pictures, and are there any extra benefits to using 'pipe-tee' systems? (Cost, safety, efficiency)
Thanks!
Jonathan :)

Re: Operating three phase high voltage power supply on single phase power

... thing: no overcurrent protection device may interrupt the connection between the boost secondary winding and the hots side of primary winding. The safety reason is obvious on inspection of a schematic, IIRC. Beware of free advice from the Internet. Hey, how about doing what amateur machinists have ...

Operating three phase high voltage power supply on single phase power

... phase motor; but they have the disadvantage of giving asymmetric output, consume wasted power turning the idler motor, are noisy, and present a safety hazard with the turning shaft (sealed idlers with no shaft are available, but they cost more than a surplus motor). Solid state phase converters ...

Re: My first plasma

... a proper metal chamber because a glass chamber will not withstand the plasma of a real fusion power supply for very long. Of course, always wear safety glasses and and ALWAYS surround any glass vacuum chamber that is under vacuum with a grounded wire screen/cage! At the very least one should ...

Re: Use of a Precipatator Power Supply

... And by the way, thanks for the Spellman link! It'll be quite a nice resource as I continue to build my HV system. I also think that it's a great safety resource for anyone who is new to HV components and sources. Sincerely, Joshua Guertler

Re: Use of a Precipatator Power Supply
