摘要：

中国环流三号自2020年建成投入运行以来，已经取得多项重要科研进展，其等离子体控制和运行水平已经得到明显提升。重点介绍了中国环流三号近年在等离子体控制和运行方面取得的进展。随着运行经验的积累，中国环流三号已经通过纯欧姆感应驱动将等离子体电流从2020年首次放电的~0.1 MA提升至1.5 MA以上，成功实现了由圆截面孔栏位形向大形变单零位形，以及雪花、鼎型等多种先进偏滤器位形的过渡。研发了大电流软着陆、破裂预测、破裂缓解等专用控制算法，有效减少了等离子体大破裂次数，从而保障了装置的安全高效稳定运行。

Abstract:

Since the HL-3 tokamak first plasma commissioning in 2020,it has achieved multiple scientific breakthroughs, with significant enhancements in plasma control and operation performance. The main progress in plasma control and operation during the past several years are summarized in this paper. With the accumulation of operational experience, HL-3 has successfully been increased the plasma current from ~0.1 MA to over 1.5 MA by ohmic heating. Additionally, the transition from circular cross-section limiter to elongated divertor configurations has been successfully achieved, including single-null and various advanced divertor with high elongation and large triangular ties. Furthermore, special control algorithms for high-current soft landing, disruption prediction, and disruption mitigation are developed. These innovative methods have effectively minimized the occurrence of plasma major disruptions, thereby ensuring the safe, efficient and stable operations of the HL-3 device.

Key words: HL-3, Plasma control; Divertor configuration, Megampere discharge, Current soft-landing
