Does somebody know anything about these guys: http://www.fpgeneration.com/index.html ?
They state to have developed and quasi spherical IEC fusion reactor with POPS technology. If you read their website it is interesting to see that they were working for Bussard in EMC2 some years ago. They also use a magnetic field to confine electrons. Are they talking about an special case of Polywell? Opinions?

M.Simon, what you refer as a gain of 6.7? I suppose they haven´t achieved yet a real gain of 6.7 because in that case they were in all the newspapers.

Sorry, I didn't state it right, I was speaking of a PoPs system implemented with Bussard's concept as discussed earlier.

GO POPS

POPS is definitely a big thing. I have suspected for sometime that a working polywell will almost definitely use some form of resonant/ oscillatory drive

MSimon where does your 1-30mz come from. It would be the resonant frequency of what ?

Does anyone have access to the PDF of those journals mentioned ?.

I am very interested in investigating this field

A plasma container with a certain size and well drive has a characteristic frequency. The frequency is dependent on the particle mass so you can tune it to Hydrogen or Boron depending on which species you want compressed. Of course with D-D it goes as n^2/2.

This paper is a good start:

http://www.lanl.gov/p/rh_pp_park.shtml

I used the curve given to derive the constant and assumed tuning for Hydrogen in my calculations.

I assumed a radius of 1.5 to 6" to derive the formula. The actual value was not given in the text. Then based on that and a 1 to 2 m radius and the drive voltages, I came up with an approximation of the frequencies.

The frequency is strictly an electrostatic phenomenon. No magnetic field enters the equation so it is different from gyro radius.

In any case - for now the exact frequency is not too important. It can be determined by experiment. What is important to know is the approximate range as it will give us an idea of how difficult it will be to generate and control.

I may have some papers on this. I'll see if I can find the Links.

Some more:

One of the givens for POPS was a thermalized plasma.

The frequency may be different if the energies are bunched. Or the bunching may make the Q (electrical resonance) higher. i.e. more sensitive to control. In layman's terms it means that the useful range of frequencies is narrower.

Los Alamos is not too far from where Dr. B's lab is being set up so maybe he will be in contact with Nebel and Park.
