Together with other Columbia University researchers, members of the Paul group presented their research work at the 65th Annual Meeting of the APS Division of Plasma Physics
This year's APS DPP meeting featured many presentations from the group.
Professor Paul discussed the role of moderate-scale experiments in the US stellarator program. Graduate student Amelia Chambliss presented her study of the fast ion particle transport, with emphasis on quadratic flux-minimizing maps and integrability of ion trajectories in quasiaxisymmetric and quasihelical stellarators. Mohammed Haque presented his latest results on filamentary coil optimization for reducing HTS strain. Abdullah S Hyder showcased his ongoing work on developing simulation tool StellDOS to model Alfvén-gap density of states for stellarators. Alexandra Lachmann presented her work on evaluating alpha particle redistribution resulting from Alfvén eigenmodes using full-particle-orbit-following code SPIRAL. Antoine Baillod discussed his previous results on equilibrium β-limits dependence on bootstrap current in classical stellarators. Alexey Knyazev presented his earlier work on modeling neoclassical impurity transport with the full-f gyrokinetic code COGENT.
Following the APS meeting, the group visited National Parks – Grand Sand Dunes and Rocky Mountains – for a week-long retreat.
