Description

The laser blow-off (LBO) technique is an important approach for impurity injection and related transport studies in the magnetically confined fusion research due to its significant advantages in the quantity control, reproducibility and transient features. Recently, a multi-pulse LBO system has been developed in the HL-2A tokamak, which was updated from the single pulse preceding system by the introduction of novel designs of a two dimensional (2D) optical steering assembly. In this article, the design and setting up details of the new system is illustrated. Preliminary experimental results employing this system is presented. (author)
