摘要

当前托卡马克装置中氢同位素滞留研究通常用原位测量分析与事后样品评价两种方法

主要滞留机制为注入-捕获与共沉积。JT-60U、DIII-D、JET、ASDEX-U、C-MOD、TEXTOR和TORE SUPRA等装置的研究结果表明材料种类、偏滤器位形、瓦块结构及排列、温度等均会对氢同位素滞留产生影响。本文介绍了以上装置的研究现状

并说明了EAST氢同位素滞留的事后样品评价研究计划。

Abstract

In contemporary tokamaks

hydrogen isotope retention is evaluated by in-situ and post-mortem analyses.Mechanisms of the retention are implantation-trapping and co-deposition.Studies on hydrogen isotope retention at JT-60U

DIII-D

JET

ASDEX-U

C-MOD

TEXTOR and TORE SUPRA reveal that the nature of material

divertor geometry

structure and alignment of tiles

and temperature can affect the retention.This paper gives a review in this field of research at these tokamaks.The post-mortem plan at the EAST tokamak is briefed

too.
