A Preliminary Look at Off-Axis NBCD

• Following ARIES-ST, NBI can be considered for off-axis current drive

toroidal rotation generation in ARIES-AT.

• Here, bN = 5.38 equilibrium is considered with nea/neo = 0.2.

Beam parameters: Eb = 120 keV, injection angle= 60o w.r.t normal.

• Driven j-profile peaked at y = 0.8, similar to seed, but much broader

towards the core. May need to generate self-consistent equilibrium.
