ANS continues to expand its certificate offerings
It’s almost been a full year since the American Nuclear Society held its inaugural section of Nuclear 101, a comprehensive certificate course on the basics of the nuclear field. Offered at the 2024 ANS Winter Conference and Expo, that first sold-out course marked a massive milestone in the Society’s expanding work in professional development and certification.

We study flute mode stability of a quadrupole-anchored tandem mirror plasma. The present analysis is based on a Newcomb's Lagrangian density with the assumption of small Larmor radius of the ion in the paraxial approximation. A radial eigenmode equation for flute perturbations is derived without the eikonal approximation in the flux coordinates, where the effects of E×B plasma rotation due to an ambipolar electric field are taken into account. The obtained eigenmode equation is applicable to a mode with arbitrary azimuthal mode number, and can describe interchange modes, E×B rotational modes and also Kelvin -Helmholtz modes driven by the shear effect of E×B plasma rotation.
