Re: Sharing hamfest booty images

Hamfests will help fill and supplement a true builder's junk box for future and current projects. My next big one is the Manassas fest in early June. I will both sell and hunt there. Always a good fest. It is usually hot and a hat and a canteen of water is nice to have. By 1PM, the shootin' match is...

Re: Usable Chamber?

Adding to Bob's posting, the usable pressures of D2 in small systems can be much higher than in larger assemblages. A significant FAQ on this new system wonderment is in the appropriate forum's FAQs. I could have easily given you the URL, but refuse to do so. Hunt for it yourself, if you are even sl...

Re: Inner grid size assessment

No, no such experiments have even taken place.

There are 2 or 3 FAQs dealing with grid materials, construction and sizing, based solely on typical proven functional successes.

FAQ - Magnetics

There has been in recent months discussions revolving around electromagnets. Most of this has to do with possible systems for construction of cyclotrons. Cyclotrons can produce neutrons and accelerate deuterons. Both can lead to fusion in gifted amateur hands. However, there are other uses for elect...

Re: lab electromagnet from scratch

Chris, Your measurement differential is a total non-issue. You seem to think it signifcant. So very much has to do with the critical placement of the sensor used to measure the strength. Equally important is the absolute flawlessness of the steel pole itself. Are there voids or imperfect alloying re...

Re: lab electromagnet from scratch

Simple variable gap systems of your design are fine, but all systems of your type design have coils over each round pole section and much thicker flux path pieces equal to or of greater cross sectional area than the round poles of carefully chosen high permeability steels. It all depends on the fina...

Re: High Voltage Supply?

Rex is right on! Now, it might have been profitable to critically read, for its valuable content, the FAQ you should have read. http://www.fusor.net/board/viewtopic.php?f=29&t=10994 This speaks to fusor power and voltage, much as Rex spoke of. For some strange reason it was placed in the fusor power...

Re: Supplies List

That is a great list and virtually complete. Now, do you have the $15,000 to get all that stuff, or the time and knowledge to collect most of it via surplus in good working order over 4 years for a bit over $2000?
