Abstract

Abstract:

The time and space distribution of the toroidal and poloidal magnetic field surrounding the HL-2M tokamak was simulated with the electromagnetic field simulation software CST Studio from Germany. The results show that the magnetic field intensity surrounding the neutralizer tank and ion source of NBI device was more than2?10^-3T, so the magnetic shielding of NBI neutralizer tank and ion source was necessary. Then the magnetic field distribution surrounding NBI neutralizer tank and ion source after shielding with iron was simulated with CST Studio.

Key words: HL-2M tokamak, Neutral beam injector (NBI), CST Studio, Magnetic shielding

摘要：

采用电磁场模拟软件CST Studio中的电磁工作室计算了HL-2M装置纵向和极向场线圈在装置周边的磁场时空分布。计算结果表明，在中性束注入器中性化室及离子源引出区域的磁场超过2-10^-3T，需要在注入器的中性化和离子源区域采用磁屏蔽结构。利用CST软件模拟计算了基于纯铁材料的NBI 注入器离子源及中性化区域的磁屏蔽罩内的磁场分布。
