【摘要】 为了研究CFETR上高能量粒子的行为，利用输运代码ONETWO模拟研究了聚变反应和高能量粒子的输运现象。在无中性束注入(NBI)条件下，高能量α粒子的密度是随时间逐渐减少的。在考虑NBI以后，α粒子密度有着较明显的下降。在束离子能量增加而NBI功率不变的情况下，α粒子密度除了在等离子体中心区域有一定的下降外，在其他区域几乎没有变化。在NBI功率增加而束离子能量不变的情况下，α粒子密度在等离子体中心区域有着明显的下降。更多还原

【Abstract】 In order to analyze the behavior of energetic particles on CFETR, the transport code ONETWO is used to investigate the fusion reaction and the transport phenomenon of energetic particles. Without the neutral beam injection(NBI), the density of energetic alpha particles gradually decreases with time. With the NBI, the alpha-particle density has an obvious drop. When the beam-ion energy increases while the NBI power is unchanged, the alpha-particle density has almost no change in other regions except for a certain decrease in the plasma center region. When the NBI power increases while the ion energy is unchanged, the alpha-particle density has an obvious drop in the central region of the plasma.更多还原
