  • THE attempts to heat a plasma to thermonuclear temperatures have all started from the idea that the plasma should be separated from the walls of the vessel by magnetic fields in vacuum. The purpose of this communication is to discuss another possibility, namely, to insulate the plasma from the walls by means of a magnetized gas at high pressure. As the thermal conductivity increases with temperature, a hot gas seems to be a poor insulator ; but at high temperatures, where the gas becomes… CONTINUE READING
