Reactor Configuration Development for ARIES-CS

摘要

New compact, quasi-axially symmetric stellarator configurations have been developed as part of the ARIES-CS reactor studies. These new configurations have good plasma confinement and transport properties, including low losses of alpha particles and good integrity of flux surfaces at high beta. We summarize the recent progress by showcasing two attractive classes of configurations-configurations with judiciously chosen rotational transforms to avoid undesirable effects of low order resonances on the flux surface integrity and configurations with very small aspect ratios (~2.5) that have excellent quasi-axisymmetry and low field ripples
