| Abstract: | Preliminary experiments of encapsuled pellet injection are carried out on the HL-2A device. Basic construction of the encapsuled pellet and manufacture technology are introduced. The encapsuled pellet is with the diameter ~0.76mm, thickness of polystyrene shell ~20μm and internal deuterium pressure ~1.5MPa. Experimental results show that the encapsuled pellet is intact during its flight path, and can be injected to the depth of ~12cm with the velocity of 200m?s-1. The fuelling efficiency is about 60%. |
