长脉冲托卡马克反应堆堆心物理

PHYSICS OF LONG PULSE TOKAMAK REACTOR PLASMA

本文对采用先进运行模式，具有大自举电流比值的纯感应驱动托卡马克反应堆堆心等离子体特性进行了分析。由α粒子反常扩散引起的非局域能量沉积效应对中心温度有重大影响，但基本不改变安全因子ｑ的分布。如能很好控制α粒子反常扩散。

Characteristics of long pulse inductively driven tokamak plasma in an advanced mode with large fraction of bootstrap current are considered. Non local alpha particle energy deposition due to their anomalous diffusion is a key issue for the establishment of the central temperature. This diffusion has little effect on the q profile, however. Should the alpha particle anomalus diffusion be controlled in some way, the long pulse inductively driven scenario of tokamak reactor would be feasible.
