In various experimental situations relevant to the laser fusion. such as plasma near the light entrance holes of hohlraum in the indirect drive experiments or more recently in the shock ignition direct drive a relatively long underdense plasma of corona type is encountered. which is subject to an intense nanosecond laser beam. The plasma is only weakly collisional and thus in the elec... https://www.roneverhart.com/Modern-Rectangular-Keyed-Entry-Pocket-Door-Emtek-2113/
