摘要：

This paper describes the design and operation of a new tungsten (W) injection system for impurity transport experiments in the Tore Supra tokamak. The system is mounted on a reciprocating manipulator and injects a controlled amount of gaseous tungsten hexacarbonyl, W(CO)(6) at arbitrary depth in the scrape-off layer, using an inertially activated valve. Injected W(CO)(6) is dissociated in the plasma, forming a radially localized plume of W atoms. The injector does not require an external gas feed and can perform a large number of injections from an on-board reservoir of W(CO)(6). Some examples of W injections in Tore Supra are included, demonstrating successful operation and discussing some technical issues of the injector prototype. (C) 2013 AIP Publishing LLC.
