The ITPA disruption database

A multi-device database of disruption characteristics has been developed under the auspices of the International Tokamak Physics Activity magneto-hydrodynamics topical group. The purpose of this ITPA disruption database (IDDB) is to find the commonalities between the disruption and disruption mitigation characteristics in a wide variety of tokamaks in order to elucidate the physics underlying tokamak disruptions and to extrapolate toward much larger devices, such as ITER and future burning plasma devices. In contrast to previous smaller disruption data collation efforts, the IDDB aims to provide significant context for each shot provided, allowing exploration of a wide array of relationships between pre-disruption and disruption parameters. The IDDB presently includes contributions from nine tokamaks, including both conventional aspect ratio and spherical tokamaks. An initial parametric analysis of the available data is presented. This analysis includes current quench rates, halo current fraction and peaking, and the effectiveness of massive impurity injection. The IDDB is publicly available, with instruction for access provided herein.

国际托卡马克物理活动（International Tokamak Physics Activity, ITPA）磁流体动力学专题小组牵头构建了一套多装置托卡马克中断特性数据库。这套ITPA中断数据库（IDDB）的核心目标在于梳理各类托卡马克装置中断与中断缓解特性的共性，以此阐明托卡马克中断背后的物理机制，并为更大规模聚变装置（如国际热核聚变实验堆ITER及未来燃烧等离子体装置）的研究提供外推依据。相较于此前规模有限的中断数据整理工作，本IDDB旨在为每条收录的放电炮次提供详尽的背景信息，从而支持对中断前与中断相关参数间多样关联关系的探索。当前本IDDB已收录9台托卡马克装置的数据，涵盖常规环径比托卡马克与球形托卡马克两类装置。本文对现有数据集开展了初步参数化分析，分析内容涵盖电流淬灭速率、晕电流份额与峰值因子，以及大质量杂质注入的中断缓解效果。本IDDB已对外开放，本文将提供该数据库的获取指引。
