Abstract: Exemplary pellets can be used for magnetic fusion devices for mitigating plasma disruption. In some embodiments, the pellets may be cryogenically cooled that may cause a rise in the electrical conductivity of the pellets. A high conductivity of the pellet can screen out the plasma's magnetic field from the interior of the pellet. The screening out of the plasma's magnetic field can slow the ablation rate of the pellet which may allow for deeper pellet penetration and a better suited spatial profile of deposited material for proper mitigation of the plasma disruption. In some other embodiments, the pellets may not be cryogenically cooled.
