Excerpt from Nyo-8672, Sherwood Progress Report, No. 2: July, 1957 to July, 1958
The evidence has become increasingly strong that there do exist steady shock profiles with an irreversible transition from one constant state to another without the intervention of collisions as a damping mechanism. Most of the investigation has concerned a range of parameters in which a low temperature, low 6* plasma is heated to a much higher temperature at a moderate B by a shock of moderate It was established previously that such a shock, provided that it is observable within reasonable apparatus dimensions, heats the ions almost exclusively. The wave length of the oscillating shock profile is on the order of afi/e7eeeq the entire thickness of the transition can range from several times A to many times x, depending on the parameters. A considerable amount of analytical work has been done involving all the general featunes. Exact quantitative results require numerical computation of an exs tremely intricate and non-standard type. This program is underway. **strength is measured by magnetic field ratio. *b=2up/b2 gas energy/magnetic energy.
