Expansion of a plasma into vacuum with a bi-Maxwellian electron distribution function

Blog Article

A comprehensive theory is developped to describe the expansion of a plasma into a vacuum with a two-temperature electron distribution function.The characteristics of the rarefaction shock which occurs in the Ointment plasma when the hot- to the cold-electron temperature ratio is larger than 9.9 are investigated with a semi-infinite plasma.Furthermore by using a finite plasma foil, a possible heating of the cold electrons population is evidenced, for a sufficiently large Thread Boxes hot- to the cold-electron density ratio.
