So far the models used to study dust grain-plasma interactions in fusion plasmas neglect the effects of dust material vapor, which is always present around dust in rather hot and dense edge plasma environment in fusion devices. However, when the vapor density and/or the amount of ionized vapor atoms become large enough, they can alter the grain-plasma interactions. Somewhat similar processes occur during pellet injection in fusion plasma. In this brief communication the applicability limits of the models ignoring vapor effects in grain-plasma interactions are obtained.

    We report on a simple way to operate plasma-electrode pockel's cells (PEPC), which are used as large-aperture optical switches in laser drivers for inertial-confinement fusion facilities. In the basic operation of a PEPC, one needs to produce a plasma in each of two gas-filled cells placed on...

    During pellet injection in tokamaks, a rapid movement of pellet ablation substance towards the low-field or outward major radius R direction is observed, favoring pellet injection from the high-field side in order to promote deeper fuel penetration. The motion has been attributed to a vertical...
