Optimal size for a fusor (embedment)
Posted: Fri Jul 08, 2016 3:08 pm
A serious discussion needs to be made for embedment boosted fusion in a fusor. Check out this post for details not to be covered here.

If bedment boosted fusion is a given, is there a limit to this boosting process? I feel there is. It may well be related to fusor size. and operational gas pressure at a given size.
Embedment boosts by deuteron production near the shell as deuterons are "popped out" of the shell as ions due to electron bombardment and localized shell heating due to same. This is much in the manner of an inefficient ion source over a large surface area. We wind up with deuterons created near the ideal point, (the shell), which can undergo maximum acceleration towards the grid. In the case of non-IEC fusion, we still wind up with faster deuterons for the now known gas volume fusion process...deuteron-fast neutral fusion. As pressure and voltage increase, the mean free path varies in a complicated but calculable fashion.
Could a fusor be made so large that the mean free path is such that no IEC fusion might take place, or a grossly reduced amount? IEC fusion typically means fusion occurs within the central grid focus volume. What fusion might take place would be velocity space fusion in the gas volume due to the long path radius of a large fusor. Would this resultant velocity space fusion still be great enough to offset the IEC losses due to size? The U of W and U of I fusion teams announced that most of the fusion in their very large fusion chambers were found within the gas volume and not in the grid focus region.
The counter argument might be posited that smaller is better due to the possibility of shorter mean free path for embeded detuerium at higher pressures. However there would always be high voltage issues in very small systems due to arcing.
This is an area for amateur research but means several fusor must be built to investigate the premise.
