The hot-tail runaway seed landscape during the thermal quench in tokamaks
Ida Svenningsson, Ola Embreus, Mathias Hoppe +2
Runaway electron populations seeded from the hot-tail generated by the rapid cooling in plasma-terminating disruptions are a serious concern for next-step tokamak devices such as I…
Optimization of flux-surface density variation in stellarator plasmas with respect to the transport of collisional impurities
Stefan Buller, Håkan M. Smith, Albert Mollén +2
Avoiding impurity accumulation is a requirement for steady-state stellarator operation. The accumulation of impurities can be heavily affected by variations in their density on the…
Impurity transport and bulk ion flow in a mixed collisionality stellarator plasma
Sarah L. Newton, Per Helander, Albert Mollén +1
The accumulation of impurities in the core of magnetically confined plasmas, resulting from standard collisional transport mechanisms, is a known threat to their performance as fus…
Numerical calculation of ion runaway distributions
Ola Embréus, Sarah Newton, Adam Stahl +2
Ions accelerated by electric fields (so-called runaway ions) in plasmas may explain observations in solar flares and fusion experiments, however limitations of previous analytic wo…
