• Considerations are presented on the wall protection of inertial confinement fusion reac-tors by means of a falling cylindrical curtain of liquid metal that is intermittently contricted into a string of closed envelopes by the action of a series of cusped fields generated around the falling liquid cylinder. The formation of a liquid metal envelope in free space is dis-cussed and the motion of the liquid curtain during constriction is numerically analyzed under the assumption of infinitesimally small curtain thickness and infinitely large conduc-tivity. The single-turn cusp-field driver coils are assumed to have a circular cross section. The calculations indicate that the energy required for the driving field is quite small com-pared with the thermonuclear energy produced per pulse, and that an adequate electro-magnetic force is generated by the coils for a 1 m radius cylindrical curtain of liquid lithium if it is constricted into closed envelopes within an interval of 30 ms.
