Re: Radio waves to increase fusion yield

No! The proximity of the antenna or coil would shunt the RF near a view port. Some small amount might get in, but all the RF issues remain. RF will not penetrate a sealed, grounded metal fusor shell from the outside. A tank coil wrapped around a glass tube filled with gas will work.

Re: LENR / Solid State Fusor

I can't ad much to what Dennis has posted. We cannot and will not, as amateur fusioneers, ever do D-T fusion. Looking at the charts, outside of D-T fusion, D-D fusion is the very finest fusion and has a good and useful slope up to 100 kev which is the absolute voltage limit for the most aggressive a...

Re: Radio waves to increase fusion yield

No! You cannot blast a fusor externally with high frequency microwaves! The magnetron must be part of the grounded shell with the stub into the chamber. However, good design needs to figure on reflections and VSWR issues to avoid blowing the magnetron up due to reflected energy. Microwave technology...

Re: Current draw at a fuel pressure

The beauty of a solid metal sphere is that large amounts of RF energy can be injected into the grounded chamber and it will act as a shield. Injecting that energy in a useful manner is the real issue.

Re: Radio waves to increase fusion yield

RF is a great ionizer. Any microwave oven can do that easily. Tom Ligon had two magnetrons connected to Doc Bussard's 3 foot diameter fusor in 1997. His result were negative as to improved fusion. A few here have used RF as a source of ionization in simple ion sources. Naturally, there is a danger o...

Re: Vacuum kit suggestions

Pretty much demo only. A diffusion or turbo pump is needed after the mechanical pump to warrant a low enough vacuum to allow a significantly pure deuterium gas environment.

Read the FAQs!!!

Re: Current draw at a fuel pressure

Nothing teaches like the doing and the "hands-on-imperative". To test anything one assumes good, if not the best, instrumentation attached to a project or experiment and the knowledge of how to use it properly. Good data is worth its weight in gold, especially if someone can draw good conclusions fr...

Re: Hello from Arlington, TX, USA

No math just details on how those early efforts handled or rather, tried to handle plasma, and how they failed to produce any usable fusion energy. All the best on trying to understand plasma physics via math. Controlled fusion demands rigidly controlled, idealized and theoretical conditions. Man is...

Re: LENR / Solid State Fusor

I, personally, have no thoughts on solid state or even plasma fusion. I only have eyes and ears for experiment that leads to novel and positive acting solutions and processes that really do controlled fusion, either far below unity return, (power hogs like the fusor), or in net gain fusion far excee...

Re: Current draw at a fuel pressure

No real need to do the experiment. Their is no optimum pressure. The general rule is you want the most pressure you can get within you power supply's ability to supply high voltages and high currents without melting the inner grid or damaging your power supply. Sadly, you are current limited to ~10m...
