Jason,

The maxwellian-boltzmann ideal distribution is found in most supposed neutral plasmas. The fusor is a confusion of mixtures of ions and neutrals, both slow and fast, all at variying velocities. I am sure the mayhem follows no standard delineated scheme in physics.

Quantifying and pinning down all that goes on in a fusor is like trying to herd cats. Still, it just works. It does fusion.

In many fusion machines the "maxwellian tail" over on the far right is where the few fusion ready ions exist.

It would indeed be hard to measure and quantify. However in a perfectly stable fusor, (such a thing never exists), doing fusion, the result might be maxwellian in nature. Seems reasonable, but many things in this soup tend to defy reason.

Basically, this is determined by the Stefan–Boltzmann law. This describes the amount of power a black body radiates at a given temperature. In the real world, this is modified by the reflectivity or albedo of the object in question, the temperature of its surroundings, and their physical geometric arrangement.

Basically, the Stefan–Boltzmann law states that an object at a certain temperature emits a certain power isotropically. Any local objects nearby will also obey the same law. The temperature of the object in question is just the balance of the differential equations of the local objects close enough to matter. Basically, how hot are your neighbors, how shiny are you all, and how much solid angle to you all occupy.

For sections of solid angle looking out into deep space, you can use the Cosmic microwave background as the effective temperature.

You will find that things cool down super fast when facing deep space and heat up super fast when facing sol. This is the main reason behind 'space blankets' you see on satellites, if you drastically reduce the surface reflectivity you drastically reduce the energy transfer between to given objects.

Sorry so late on the reply, Jason. I do not actually believe there is any relation to any comprehensible scientific status ever defined within the fusor. It is probably possible to guess at generalities like the fusor in stable operation, if you believe there is any stability within the fusor, might have a tendency towards the maxwellian with perhaps a very short tail, (high energy particulates related to the highest applied voltage). Only a smooth, non-accelerated, steadily energized ionized gas might tend towards the ideal maxwellian. (Glow discharge)

Even generalities regarding the fusor are just ideas based on interpretations of known physics....Best guesses and such guesses may just refer to specific regions within the fusor and fall apart in other regions behaving in a different manner within their velocity space or the walls or at the grid.

Again, the import and purpose of this entire thread is to relate the "Ouch!, That's hot!...Oh it burns!... Me hurt" concept of normal, dense matter ideas of heat and temperature in the mind of the common Joe to the more nebulous concept of the over-blown, over-stated Billions of degrees needed to do fusion. This is often quoted by physicists to deceive a public they know hasn't got a clue, but are suitably impressed by such high temperature statements. The average Joe has to think, "Gee whiz these guys are really trying to work with and contain stuff that is really hot beyond my ability to even conceive of..." We know they are thinking "Ouch, that's hot"...... Of course, it is not hot at all in the only reality they are familiar with.
