Stellarators with enhanced tritium confinement and edge radiation control

Nuclear Fusion
A stellarator design is described with the purpose of achieving three goals: (1) enhance the confinement time of tritium. (2) Have a sufficient density of high- Z impurities to radiate the thermal power escaping from the core while having an extremely ...

Core plasma fueling by fast inward particle transport after hydrogen pellet injection in Wendelstein 7-X

Nuclear Fusion
A large database of more than 1000 individual cryogenic hydrogen pellets injected into Wendelstein 7-X for plasma fueling was analyzed to improve the understanding of the three phases of the process: the ablation, deposition and transport of the pellet ...

Computation of the Spitzer function in stellarators and tokamaks with finite collisionality

EPJ Web of Conferences, 2015
The generalized Spitzer function, which determines the current drive efficiency in toka- maks and stellarators is modelled for finite plasma collisionality with help of the drift kinetic equation solver NEO-2 [1].

Quasi-Isodynamic Stellarators with Low Turbulence as Fusion Reactor Candidates

PRX Energy
The stellarator is a type of fusion energy device that—if properly designed—could provide clean, safe, and abundant energy to the grid. To generate this energy, a stellarator must keep a hot mixture of charged particles (known as a plasma) sufficiently ...

Investigating the role of divertor geometry on density build-up in the island divertor

Nuclear Materials and Energy
The island divertor has been proposed for power and particle exhaust in stellarators. It is investigated in the Wendelstein 7-X (W7-X) experiment. The divertor capabilities such as particle exhaust or radiative power dissipation scale with the divertor ...
