Abstract
- As the first divertor tokamak in China, HL-2A device has been successfully operated and stably sustained in the single-null divertor configuration under good feedback control of plasma current and position. Up to now, the following operation parameters have been achieved: Ip = 400 kA, Bt = 2.6 T and discharge duration Td = 2980ms. An excellent repeatability of discharge has been achieved and about 90% Greenwald density limit has been reached. The HL-2A SN divertor configuration can be simulated by the SWEQU code and identified by CCD imaging system and CF code. The experimental results proved that the divertor configuration and siliconization could strongly decrease the plasma radiation and impurity emission and reduce the recycling effectively. Density limit disruption has been analyzed and some interesting phenomena, such as asymmetric cold pulse perturbation and snake-like perturbation, have been observed during Molecular Beam Injection. © 2006 American Institute of Physics [ABSTRACT FROM AUTHOR]
