Patent Number: 054870941
Section: abstract

A pellet carrier disc is movably held between two cooling blocks. The disc is vertically moved, setting its through hole into axial alignment with a first hole of the block. Deuterium gas is supplied into the through hole through the hole, and cooled and solidified, forming a deuterium cylinder. Then, the disc is moved, axially aligning the hole with a second hole of the block. A shaft is thrust into a first end of the deuterium cylinder through the hole, thereby forming a hole in the end of the cylinder. Next, the disc is moved, axially aligning the hole with a third hole of the block. Tritium gas is introduced into the hole of the cylinder through the hole, and cooled and solidified, forming a tritium core. Further, the disc is moved, axially aligning the hole with a fourth hole of the block. A shaft is moved through the hole, causing the second end portion of the deuterium cylinder to project from the hole. The second end portion of the cylinder is cut off. An additional amount of deuterium gas is applied on to the first end of the cylinder, and cooled and solidified, forming a layer covering the tritium core.
