Pellet injection in magnetic confinement fusion devices

Abstract

Interest in plasma physics regarding the injection of high-speed solid D/sub2/ pellets in magnetic confinement fusion devices has enormously increased in recent years since this technique allows one to control fuel deposition and improve some of the most relevant plasma parameters such as energy confinement, plasma stability and density profiles. Pellet injection is also a very powerful tool for diagnostic purposes, providing an experimental method to study particles and impurity transport properties. Work has been accomplished, from both theoretical and experimental points of view, in order to predict and to investigate the behaviour of a cryogenic pellet in a hot plasma environment. At the same time, a technological effort, performed by several laboratories in the world, has brought about the realization of a first family of `conventional` injectors; the development of a new generation of devices aiming to achieve higher performances is in course. A brief review of the main physical issues concerning pellet injection and a description of the activities pursued at the ENEA (Italian Agency for Energy, New Technologies and the Environment) Frascati Center working on the development of high-speed pellet injectors are given.
