Re: #4 FAQ: vacuum gauges - pressure measurements

We have had so many people here ask if the common 270 degree sweep, round, direct reading gauge is good enough for fusor work, I felt compelled to amend the very beginning post of this FAQ to lead off with a statement that such a gauge will not do for fusor based vacuum readings. Dare I hope folks w...

Re: Vacuum kit suggestions

The two stage vacuum pump looks OK. However, the vacuum gauge is not good for the vacuum needed for even a demo fusor.

Re: Abstracts posted for 20th US-Japan IECF Workshop

A study of the original Desert cart fusor demo'd before the AEC by Hirsch and Meeks in 1967 utilized a heated filament and ionizer grid outside of the anode grid. The cubic system takes advantage of the sharp high field emission points. I have mused over the cross and Tee type small, successful fuso...

Re: Frequency effect in the operation of a MOT.

I have not responded yet to allow the experiment to be done as this is the best teacher of all. Something you do to learn. In general, an iron core laminated transformer designed for 60 hz cannot be used at much higher frequencies due to the mass of iron needed to make it work at its rated 60 hz fre...

Re: Greetings from Spain.

Any thing that is desired to be obtained is always worth the effort needed to obtain it. This is especially true if it is to obtain knowledge and skills.
Welcome to the forums, Cai.

Re: Jan Ruge Fusion Attempt @ Chaos Darmstadt

60hz multipliers suffer from the need to have larger capacitances, (dangerous energy storage), to have significant current capability. High frequency multipliers do far better with lower stored energy capacitors. Unfortunately the initial high voltage transformer is typically weak and not capable of...

Re: Jan Ruge Fusion Attempt @ Chaos Darmstadt

You are moving towards some sort of success. Far more important than mere successful fusion is that you are learning a lot by "the doing" and hands on observations in a slow and careful march towards your goal. When you arrive at your goal, you will "own" a lot of concepts others merely read about a...

Re: “Magnetically insulated grid IEC”

A fabulous way to get cash in exchange for a paper voucher promising electricity yet to be produced by any fully disclosed method. I know, "take my word" for it...."real soon now". The quest for gullible suckers never ends. The firm belief that there is one born every day has kept a lot of pitchmen ...

Re: Plasma between two alternating electrodes?

Better still, spend your money and effort trying your idea in hardware and learn the hard way, it won't work. It will also teach you that self-directed reading on various subjects related to the fusion effort pays dividends. The fusion we do is certainly the easiest of all methods that is readily ve...

Re: Archived - Tom McCarthy's Fusor Efforts

Through clear glass, free of deposits, A deuterium plasma is pink to red. It doesn't take long for a view port to become occluded by deposits which shift the color to a great degree. Fusor IV's current color image is black and white using a color camera. This deposit plagues view ports of folks who ...
