摘　　要：对托卡马克抽气限制器的原理以及设计原则进行了详细论述。对抽气限制器及等离子体行为的影响、边界粒子排灰效率进行了论述和计算，设计出一个小而灵活的HT-6M抽气限制器，并在装置上进行了初步的物理实验。明显地观测到等离子体参数的改善，密度极限从2.4×1013／cm3上升到2.8×1013／cm3。等离子体能量及粒子约束时间都得到改善，从而证明抽气限制器是个非常有效的粒子控制部件。The principle and design methods of Tokamak pump limiter are presented in detail. Plasma edge particle control by pump limiter and its particle exhaust efficiency are given and calcutated. A small flexible HT-6M pump limiter was designed,installed and preliminary experiments were carried out on HT-6M Tokamak. The plasma performance improvement was observed. The density limit was increased from 2. 4 × 1013cm-3 to 2. 8×1013cm-3. Plasma energy and peticle confinement time were improved. All of these demonstrate that the pump limiter is a very useful tool to control the peticle transport.
