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 …

Plasma fuelling with pellet injection, pacing of edge localized modes (ELMs) by small
frequent pellets and disruption mitigation with gas jets or injected solid material are some of …

Edge-localized mode (ELM) triggering and pacing in an all-metal wall environment shows
significant differences to a first-wall configuration containing carbon. Here we report on …

During the installation of the new ITER-like wall (ILW) at JET, the high frequency pellet
injector has been further improved. The launching system is now capable of delivering …

A new pellet injection system was installed at JET designed for both fuelling and ELM
pacing. The purpose of the pacing section was to validate pellet ELM pacing as a suitable …

Abstract The Demonstration Fusion Power Reactor DEMO is the step foreseen to bridge the
gap between ITER and the first commercial fusion power plant. One key element in the …

This article investigates the triggering of ELMs on JET by injection of frozen pellets of
isotopes of Hydrogen. A method is established to determine the probability that a specific …

Cryogenic pellet injectors for use in fusion research have been under development at Oak
Ridge National Laboratory for over 30 years. The original application of the technology was …

Three innovative repetitive and multi-barrel deuterium ice pellet injectors have been
designed for plasma investigations in fusion facilities. The pellet injector for JET can inject …

In the last few decades, pellet injection has become an important tool of discharge operation
and control. In ITER, plasma fuelling and edge localized mode (ELM) pacemaking will rely …
