Abstract :
Establishing control parameters for the delivery of cesium is paramount for the successful operation of the high current multi megawatt negative ion beam sources, required for fusion. The merit parameter of cesium lies in its attribute of reducing the work function of the surface of the plasma grid of the ion sources and facilitate the production of negative ions (of H/D) by the surface production process.
