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 …

Steady progress has been made worldwide in the application and development of hydrogen
pellet injection as a method for fuelling magnetically confined plasmas. The theoretical …

Pellet injection is the primary fueling technique planned for core fueling of ITER burning
plasmas. Also, the injection of relatively small pellets to purposely trigger rapid small edge …

High repetition rate injection of deuterium pellets from the low-field side (LFS) of the DIII-D
tokamak is shown to trigger high-frequency edge-localized modes (ELMs) at up to 12× the …

Pellet injection is an important technique used for fueling and density profile control in
magnetically confined plasmas that has been investigated for many years. 1 Much effort in …

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 …

Deuterium pellets have been injected into plasmas in the DIII-D tokamak from the inner wall,
top, and outer midplane port locations to investigate fuelling efficiency, mass deposition and …

The injection of small deuterium pellets at high repetition rates up to 12× the natural edge
localized mode (ELM) frequency has been used to trigger high-frequency ELMs in otherwise …

The next generation of fusion machines like ITER and DEMO will need a reliable method for
controlling the periodic transient expulsion of a considerable amount of energy onto the …

Abstract The International Thermonuclear Experimental Reactor (ITER) will use an
advanced, high-velocity pellet injection system to achieve and maintain ignited plasmas …
