During the last 10 to 15 years, significant progress has been made worldwide in the area of
pellet injection technology. This specialized field of research originated as a possible …

The injection of frozen pellets composed of the isotopes of hydrogen has become the
leading candidate for refueling fusion power reactors based on the tokamak concept. This …

Solid hydrogen spheres were injected into the ORMAK tokamak as a test of pellet refuelling
for tokamak fusion reactors. Pellets 70 μm and 210 μm in diameter were injected with …

The feasibility of re-fuelling a fusion reactor by injecting pellets of frozen hydrogen isotopes
is reviewed. First a general look is taken of the dominant energy fluxes received by the …

High-speed injection of solid fuel was first proposed in 1954 as a possible solution to the
problem of transporting fresh fuel across the confining magnetic fields into the plasma of a …

High-speed pellet fuelling experiments have been performed on the ISX-B device in a new
regime characterized by large global density rise in both Ohmically and neutral-beam …

Hydrogen pellet ablation and acceleration by current in high temperature plasmas are
analysed. The present state of ablation theory and experiment is discussed and an ablation …

During the last decade, significant progress has been made in the field of pellet injection
with (1) the identification of the drift of the deposited material in the inhomogeneous …

A repeating pneumatic pellet injector has been developed for plasma fueling applications.
The repetitive device extends pneumatic injector operation to steady state. The active …
