论文摘要
在研究迭代器中断的热淬灭阶段后，使用破碎的颗粒注射的可能性，以便在研究大量雪崩之前耗尽失控的电子（re）种子。给出了碎片所需的注入速率的分析和数值估计，以渗透到形成的RE束和停止RES中。还估计了当前淬火（CQ）太短之前可以吸收多少材料。看来，如果使用了氢气，则在CQ期间要注入所需的颗粒数量，至少考虑到ITER干扰系统（DMS）的当前设计。对于霓虹灯或氩气，所需的颗粒数虽然很大，但可能在ITER DM的范围内，但是同化的部分必须很小。其他材料可能更适合，但需要修改ITER DMS。
The possibility of using Shattered Pellet Injection(s) after the Thermal Quench phase of an ITER disruption in order to deplete Runaway Electron (RE) seeds before they can substantially avalanche is studied. Analytical and numerical estimates of the required injection rate for shards to penetrate into the forming RE beam and stop REs are given. How much material could be assimilated before the Current Quench (CQ) becomes too short is also estimated. It appears that, if Hydrogen pellets were used, the required number of pellets to be injected during the CQ would be prohibitive, at least considering the present design of the ITER Disruption Mitigation System (DMS). For Neon or Argon, the required number of pellets, although large, might be within reach of the ITER DMS, but the assimilated fraction would have to be very small. Other materials may be better suited but would require a modification of the ITER DMS.
