| Abstract: | A variable-cross-section extruder, in which rheological properties of solid-state hydrogen isotopes are used for manufacturing ice suitable for forming fuel pellets of thermonuclear facilities, was for the first time designed. The fuel injector for fueling the HL-2A tokamak (SWIP, China) by deuterium pellets with a 1.3-mm diameter, a length of 1.3–1.7 mm, a velocity of 100–450 m/s, and a frequency up to 33 Hz has been designed based on it. |
