Abstract
The first injector design capable of injecting an unlimited supply of fuel pellets into a fusion reactor plasma in prolonged, continuous operation is reported. More than a thousand pellets 2 mm in diameter are formed without interruption from the screw extruder at frequencies of 1 Hz and 2 Hz and are accelerated to 0.8 km/s.
