| 摘 要： | Neutrals beam injection （NBI） has proven to be a very effective method for plasma heating. A set of positive-ion-based NBI system is being designed, manufactured and tested at ASIPP. The aim of this study was to ascertain the most effective cryocondensation pump structure for the hydrogen NBI system. The parameter design and mechanical design were made to determine the optimum parameters and structure of the cryocondensation pump. The lowest pressure of 7.2 × 10^-6 Pa was achieved in the vacuum chamber, which indicated that this type of liquid helium cryocondensation pump could meet the requirement of the NBI system quite well.
