The current conception of fueling large fusion devices is based on gas puffing and pellet
injection. A pellet injector produces, accelerates, and transports millimeter-size pellets …

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

A new single-shot hydrogen pellet injector based on a simple" pipe gun" design is
described. In the cryogenic gun block, the 4-mm-diam (nominal) pellet is frozen in situ …

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 pellets of frozen hydrogen isotopes into fusion plasmas is envisioned as a
fueling technique for future fusion reactors. Research is underway to obtain high injection …

Plasma fueling via injection of solid hydrogenic pellets has expanded the operating range
for tokamaks and stellarators to higher densities than attainable with gas puffing. Pellet …

We describe the design and operation of the solid hydrogen pellet injection system used in
plasma refueling experiments on the ISX tokamak. The gun‐type injector operates on the …

An eight‐shot pneumatic pellet injection system has been developed for plasma fueling of
the tokamak fusion test reactor (TFTR). The active cryogenic mechanisms consist of a solid …

In tokamak fusion reactors, plasma disruptions may be the limiting factor in the lifetime of the
first wall and divertor components. The large heat fluxes generated by the rapid, local …

A repeating pneumatic pellet injector has been constructed to experiment with the technique
of continuous injection for fueling fusion reactors. This device is composed of a cryogenic …
