SUMMARY:"Advances in optimization for stellarator design"\, Plasma Phy
 sics (Physics/ECE/NE 922) Seminar\, Elizabeth Paul\, Columbia Universi
 ty
DESCRIPTION:The immense freedom in the stellarator design space provid
 es opportunities for reducing engineering complexity and improving con
 finement. This talk will provide an overview of recent advances in ste
 llarator optimization and their application to the design of new exper
 iments in the Columbia Plasma Laboratory. Recently\, “precisely quas
 isymmetric” configurations have been obtained\, demonstrating excell
 ent confinement of fusion-born alpha particles in the absence of pertu
 rbations. There is\, however\, the potential for enhanced alpha losses
  due to resonant wave-particle interactions. We present pathways to mo
 del and optimize the alpha transport driven by Alfvenic instabilities 
 through modification of the resonance structure and shear Alfven conti
 nuum. Furthermore\, we discuss the incorporation of engineering constr
 aints\, including HTS strain and remote maintenance compatibility\, in
 to the stellarator design process. The Columbia Plasma Laboratory will
  validate these advances. The Columbia Stellarator eXperiment (CSX) wi
 ll build on the success of the Columbia Non-neutral Torus (CNT) to con
 fine a small aspect ratio quasisymmetric plasma with two shaped interl
 inked coils. Using this device\, we will explore the physics of quasia
 xisymmetry and demonstrate non-insulated HTS technology for non-planar
  magnets.
