摘要
本文介绍了模拟等离子体电流环电流在HL-1装置铜壳的1/4段上感应的涡流,在等离子体区产生的磁场大小、分布和时间特征的测量结果.涡流产生的垂直场随着等离子体电流环水平位移和电流上升率的增加而增加,而且在空间各点的大小和衰减时间常数都不相同。极向缝隙使涡流产生的垂直场和水平场沿大环方向呈周期性变化,环向缝隙对垂直场没有影响,但是却大大减弱了涡流产生的水平场。
Using a plasma simulator,the magnitude,distribution and time behavior of the magnetic field generated by the eddy currents in a quarter segment of the HL-1 copper shell were measured.The vertical field generated by the eddy currents in the shell increases as the simulator mores outwards.The magnetic field and its damping time constant at various points inside the shell are different from each other.While poloidal gaps make the vertical and horizontal fields generated by the eddy currents change periodically in the toroidal direction,toroidal gaps have no effect on the vertical field,but drastically reduce the horizontal field.
