Wall conditioning with impurity pellet injection on TFTR
Solid lithium and boron pellets have been injected into TFTR plasmas to improve plasma performance by coating the graphite inner wall bumper limiter with a small amount of lower Z pellet material, which reduces the influx of carbon from the walls and reduces the edge electron density. This new wall conditioning technique has been applied successfully when continued He conditioning discharges, w...
متن کاملSimulation of Runaway Electron Generation During Plasma Shutdown by Impurity Injection in ITER
Disruptions in a large tokamak can cause serious damage to the device and should be avoided or mitigated. Massive gas or killer pellet injection are possible ways to obtain a controlled fast plasma shutdown before a natural disruption occurs. In this work, plasma shutdown scenarios with different types of impurities are studied for an ITER-like plasma. Plasma cooling, runaway generation and the...
متن کاملDevelopment of a particle injection system for impurity transport study in KSTAR.
A solid particle injection system is developed for KSTAR. The system has a compact size, compatibility with a strong magnetic field and high vacuum environment, and the capability to inject a small amount of solid particles with a narrow injection angle. The target flight-distance of 10 cm has been achieved with a particle loss rate of less than 10%. Solid impurity particles such as tungsten an...
متن کاملImpurity Transport Experiments in the Edge Plasma of Alcator C-Mod using Gas Injection Plumes
Understanding impurity and bulk plasma transport in the scrape-off layer (SOL) of tokamak plasmas is critical for the design of future reactors. The development of a system on Alcator C-Mod for inferring impurity transport behaviour parallel and perpendicular to local magnetic field lines from impurity emission patterns (“plumes”) generated by local gas injection will be presented. Gas is injec...
متن کاملImpurity profiling and in-process testing of drugs for injection by fast liquid chromatography
Liquid chromatography (LC) is considered by many as a mature technique. Nonetheless, LC technology continues to evolve driven by the need for high-throughput and high-resolution analyses. Over the past several years, small particle size packing materials have been introduced by several column manufacturers to enable fast and efficient LC separations. Several examples of pharmaceutical analyses,...
