Abstract:
New repetitive multibarrel pellet injector for steady-state fueling and diagnostics purposes in large fusion devices has been designed. The injector is intended to apply in the Large Helical Device at the National Institute for Fusion Science in Japan. The steady-state operation is provided by ten pipe-guns with unique porous units forming solid hydrogen pellets for 5 - 9 s in every barrel. Over one thousand hydrogen pellets have been formed and accelerated to 1.2 km/s at the different repetitive rates. The injector design and experimental results are presented.
