Dr. Gates is the stellarator physics leader at PPPL. In this role he acts as the US Technical Representative for the International Collaboration on Superconducting Stellarators. He is also the Principle Investigator of an ARPA-E project entitled “Stellarator Simplification using Permanent Magnets”. At Andlinger, Dr. Gates is also performing research on the improvement of stellarator designs and has recently submitted a proposal entitled “Using permanent magnets for near perfect quasi-symmetry in a stellarator”.  Stellarators are a type of plasma containment device that has great promise for creating fusion energy.
