Impurity Behaviours of HL-2A Divertor Tokamak during the Initial Operation Period
《Southwestern Institute of Physics Annual Report》2006年第1期34-35,共2页CUI Zhengying SUN Ping PAN Yudong LI Wei WANG Quanming CAO Zeng WANG Mingxu 
Supported by the National Natural Science Foundation of China （ 10475022 ）The authors would like to thank all of our colleagues working on HL-2A, particularly LU J., LU E, FU B. Z. and LU0 C. W. for their assistance in the experiment on HL-2A.
In order to avoid destroying the vessel wall and poisoning the plasma, at the same time to efficiently extract the waste product of the fusion process from the system, divertors were adopted in some machines just at t...
