- Actually, there are other considerations. One would like to get electrons
- moving through a gas of a certain density. The problem is that when using
- a low voltage gradient approach the electron will probably lose all of its
- gained energy (on the average) due to collisions with gas atoms. Thus a
- discharge will not "get started". Using lower gas density will help
- (longer initial mean free path). To make matters worse, oxygen will even
- adhere electrons to form negative molecules.
-
- If the gradient is high (sharp) enough so that the electron can gain
- enough energy between collisions from the field to free another electron
- or more from the gas then it is more likely it will speed up between
- collisions and the faster it goes the longer the mean free path gets
- (lower the collision cross-section). Consequently, such electrons runaway
- until the field decays with distance to an insufficiently supporting
- level. Once conducting paths are formed from the excess production of
- electrons, they become current streamers which light up and usually can
- be seen. For example from a laboratory hand tesla coil discharging into
- open air. The light probably eminates from back flowing ions generated
- along the track (recombinations).
-
- So ... after selecting an appropriate range of gas pressures, the case
- depicted above on the right may disharge while the one on the left will
- not.
-
- Now back into the discharge path and fusion.
-
- Ions generated by the electron removal would then be free to zap
- inward toward the sharp high gradient point. Note that the very first
- ions arriving maybe what breaks lose a really strong avalance of ions.
- The first ones arriving would then be inertially compressed
- by the following much denser radially closing ion wave. But ---
- I'm sure you realize this part is pure speculation and even if somewhat
- true, the effect may not be anywhere near good enough to produce
- commercial levels of fusion or aneutronic energy. -- in this business,
- Who knows.
