SUMMARY:The magnetic field scale length: an influential property of st
 ellarators\, Plasma Physics (Physics/ECE/NE 922) Seminar\, Matt Landre
 man\, University of Maryland
DESCRIPTION:A scale length can be defined based on the gradient of the
  magnetic field vector. This information can be useful for optimizing 
 magnetic fields for fusion and understanding constraints on the magnet
 s that produce them. Here we present two applications for the stellara
 tor fusion concept. First\, when expanding about the magnetic axis\, m
 aximizing the field scale length can increase the volume in which quas
 isymmetry is achieved. Second\, the field scale length is shown to con
 strain how far away the electromagnetic coils can be from the plasma. 
 Increasing the field scale length can therefore improve confinement\, 
 increase clearances for engineering\, and reduce the size and cost of 
 a fusion reactor.
