Decompressive (cooling rarefaction) shock in optically thin radiative plasma

DK Morozov, M Pekker - Physical Review E, 2001 - APS
It is shown that the decompressive shock, ie, a shock where the pressure behind the front is
smaller than the pressure ahead of it, is possible in a radiative plasma; this is in contrast to …

A possible mechanism for the generation and motion of blobs in tokamaks

VP Vlasov, BA Trubnikov - Plasma Physics Reports, 2003 - Springer
A possible mechanism for the generation and motion of so-called blobs—peculiar
