Notes:
A novel technique for the injection of small (diameter ≤30 μm) impurity pellets into fusion plasmas is proposed and investigated. The method may be easily applied by using a special target plate in conventional laser blow-off injection devices. In the present experiments 10×30×30 μm size aluminum pellets (≈5×1014 atoms) are accelerated to average velocities up to 1 km/s by a 700 mJ ruby laser pulse. The scaling law obtained from a rocket model to the pellet velocity versus laser fluence fits well to experimental data and enables one to extrapolate the capabilities of the technique. © 1995 American Institute of Physics.
