The hydrogen to boron ratio in diborane is closer to an optimal value as well I believe. I gather the sweet spot between fusion reaction rate and bremstrahlung losses is about 5:1 of p:B11.
What would a more or less fully dissociated partially ionized mixture naturally condense to?
I had always thought that the bulk gas in the chamber would, after a shot cool to a few thousand degrees, before the next pulse when operating at a high rep rate. Obviously during these experiments it will quickly cool to the chamber/electrode temperature. Would free boron & hydrogen atoms recombine to form complex molecules that could condense onto the walls.
