雪花偏滤器（SFD）控制和分离控制，以管理在偏滤器的热通量成功地证明在DIII-D。这两个热通量减少控制方法的开发和实施的结果。SFD控制算法实时计算两个零点的位置，并控制成形线圈电流，以实现和稳定各种雪花配置。分离控制在整个射击过程中稳定固定在打击点和X点之间指定距离处的分离前沿。(C)2014爱思唯尔有限公司版权所有。
The snowflake divertor (SFD) control and detachment control to manage the heat flux at the divertor are successfully demonstrated at DIII-D. Results of the development and implementation of these two heat flux reduction control methods are presented. The SFD control algorithm calculates the position of the two null-points in real-time and controls shaping coil currents to achieve and stabilize various snowflake configurations. Detachment control stabilizes the detachment front fixed at specified distance between the strike point and the X-point throughout the shot. (C) 2014 Elsevier B.V. All rights reserved.
