Since resonance in the Fusor appears to be of emerging interest, I have some relevant data that came from my interest in building another device.

Here is some nuclear magnetic frequency data (at 1 Tesla) (from CRC HAndbook, 74th Ed.,p. 9-156):

Isotope Freq. (MHz)

1n 29.1639
1H 42.5764
2H 6.53573
3H 45.4137
2He 32.4352

There are some ways this might be applied to a fusor, but it would not be as easy to do in a Fusor as in a device that operated under non-plasma conditions.

This following is the description of an experiment that I am currently building. It is a little off topic for this forum because it is not a Fusor... though there are similarities and the ultimate goal is also to extract energy from Deuterium. Any comments or advice would be appreciated.

A lot of the inspiration for my experiment came from Farnsworth and the laudable efforts of Richard and others who have demsonstrated that it might be possible to advance the technology of D fusion without megabuck budgets...closer to a shoestring budget I might add.

My device is a low energy device that uses crossed-field permanent NIB magnets together with RF at the NMR resonant frequency of either D or H or n - the hope being that enough resonance can be introduced, assuming the neutron and proton are fairly isolated in the D nucleus (as its radius suggests) - so that when one stimulated far in excess of the other, the neutron will either strip or exchange in a reaction that is much lower energy that D-D fusion . The vacuum chamber is a small solenoid of less than 10 cu in. and the RF is less than 40 watts coing from an old transmitter.

Specifically, by stimulating D at 42.5764 MHz or 29.1639 MHz it might tend to torque one and not the other end of the "barbell" shaped D nulceus - at least that is the theory. The end result might be something similar to D decay.

Yes, for those who weren't aware, D will occaionally spontaneously decay, even though all the textbooks will tell you that it is a stable isotope. The event is so rare that no "half life" can be estimated- at least I have never run across one.

To be honest, I would have prefered to build a Fusor but I had most of the equipment for this device. If I am unsucessful but not discouraged (and win the lottery) I will move up to a fusor and try to incorporate some resonance effects into it. NMR usually requires crossed fields- one of which is usually supplied by magnets. They would have to be very large for use with a Fusor.

In the meantime, I am seeking a source for a small amount duterated borane. If any of you Fusorites hear of this exotic stuff let me know. Feel free to email me directly so as not to take up bandwidth from the forum. I won't be up and running for several weeks to months, but I will keep anyone informed who is interested.
