Runaway electron generation during plasma shutdown by killer pellet injection
Tokamak discharges are sometimes terminated by disruptions that may cause large mechanical and thermal loads on the vessel. To mitigate disruption-induced problems it has been proposed that “killer” pellets could be injected into the plasma in order to safely terminate the discharge. Killer pellets enhance radiative energy loss and thereby lead to rapid cooling and shutdown of the discharge. Bu...
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 کاملECRH Results during Current Ramp-up and Post-Pellet Injection in FTU Plasma
Recent ECRH experiments in FTU have provided new results in two plasma scenarios, both characterized by the absence of the sawtooth activity and by flat or reversed q profiles. The first is the current ramp-up phase where low density plasmas have been heated up to high electron temperature. When the heating is localized on the plasma axis, the high additional power density has produced the evid...
متن کاملCriteria for Runaway Electron Generation in Tokamak Disruptions
Experimental observations show that there is a magnetic field threshold for runaway electron generation in tokamak disruptions. A possible explanation for these observations is that the runaway beam excites whistler waves that scatter the electrons in velocity space and prevents the beam from growing. The growth rates of the most unstable whistler waves are inversely proportional to the magneti...
متن کاملLithium Pellet Injection Experiments
A pellet enhanced performance (PEP) mode, showing significantly reduced core transport, is regularly obtained after the injection of deeply penetrating lithium pellets into Alcator C-Mod discharges. These transient modes, which typically persist about two energy confinement times, are characterized by a steep pressure gradient (4, <a/5) in the inner third of the plasma, indicating the presence ...
