Abstract
Apparatus for producing hydrogen pellets for introduction into a plasma-physical equipment, fusion reactor or the like, comprises an extrusion cryostat T1 and a supply cryostat T2, the temperatures of which can be adjusted independently of each other. The solidified material is extruded from the extrusion cryostat T1 into the supply cryostat T2 at a relatively high temperature appropriate for extrusion, and the material is cooled in the supply cryostat to a lower temperature which is suitable for the ejection operation and which ensures high strength. The apparatus advantageously comprises a double ram 14 which is used as a whole for the extrusion and which incorporates a coaxially guided ejection ram of smaller diameter, by means of which the extruded material can be ejected from the supply cryostat at the required speed. The extruded material is prevented from freezing solid in the supply duct 76 of the supply cryostat T2 by a heating means which has a short time constant and by means of which the walls of the supply duct can be briefly heated up so as to enable the solidified material to be ejected efficiently without its being substantially heated up in the interior. <IMAGE>
