Alternative divertor target concepts for next step fusion devices

Abstract: The operational conditions of a divertor target in the next steps of fusion devices are more severe in comparison with ITER. The current divertor designs and technologies have a limited application concerning these conditions, and so new design concepts/technologies are required. The main reasons which practically prevent the use of the traditional motionless solid divertor target are analyzed. We describe several alternative divertor target concepts in this paper. The comparative analysis of these concepts (i… Show more

“…Другая не менее острая проблема -перевод ТИН в стационарный (либо квазистационарный) режим работы. Очевидно, что при этом придётся отказаться от некоторых материалов и технологических подходов, которые традиционно используются в ходе плазменного эксперимента [18]. На эти вопросы должен дать ответы будущий опыт эксплуатации ИТЕР.…”

“…Divertor magnetic configurations, including the long-legged divertor [3], snowflake divertor [4], and cloverleaf divertor [5], are optimized to reach this goal. Geometry optimizations of the divertor target are also useful, including closure divertor [6][7][8], target plate electric biasing [9], moving divertor plates [10], and scanning striking point position.…”

“…the standard X-point divertor) may be able to modify parallel and perpendicular transport, dissipative loss channels, and increase plasmawetted area. Power and particle exhaust can also be improved via optimization of the standard X-point divertor using 'nonmagnetic' means, i.e., divertor target geometry including divertor closure [12][13][14], target plate electric biasing, liquid metal targets, liquid metal curtains, moving divertor plates, or moving pebbles (e.g., [15]). However, these concepts are outside of the present review.…”
