Frozen gas pellets esp. for nuclear fusion experiments - produced without initial movement to permit accurate projection towards target

摘要

A method of making pallets of gases which solidify at very low temps. is intended for use where the pellets are to be supplied in a controlled manner to a predetermined position. A rod of the solidified gas is produced and particles are then cut in succession from the end of this rod without contact by means of thermal radiation. Pref. the thermal radiation is produced by heated wires. Used for the production and transmission of pellets of materials which solidify at =-80 degrees C. Specifically, the method is used for the prodn. of solidified pellets of gas which are to be propelled into the focal point of laser and electron beams to produce make-up fuel in experimental investigations of controlled nuclear fusion and also in fusion reactors of the future. By cutting off the pellets from the rod without any contact with mechanical parts, sideways displacement of pellets and other disturbing movements are avoided, so that they can be directly accurately to the desired location.
