On radial density profile of plasma blob injected into a curved vacuum chamber

摘要

An analytic and self consistent solution for quasi-neutral plasma transport suggests that n0 ∼ r/r0 plot is a straight line having unit slope. The model is tested with experimental findings. In our experiment a plasma gun similar to the geometry of washer plasma gun has been designed which projects high speed dense plasma blobs. Interestingly, the experimental result shows that both (ne)0e ∼ r/ro plot and (ni)0i ∼ r/ro plots are straight lines.
