Non-Inductive Current Drive and Bootstrap Fraction of a Compact Spherical-Tokamak Breeder

Non-inductive current drive and bootstrap fraction of the compact spherical-tokamak breeder. At the frozen operating point the pressure-driven bootstrap current self-generates about 15.5 percent of the plasma current and external non-inductive drive supplies the rest, its wall-plug power booked openly in the recirculating budget. The bootstrap fraction is a lever, stated modestly. Physics only.

Abstract

Non-inductive current drive and bootstrap fraction of the compact spherical-tokamak breeder. At the frozen operating point the pressure-driven bootstrap current self-generates about 15.5 percent of the plasma current and external non-inductive drive supplies the rest, its wall-plug power booked openly in the recirculating budget. The bootstrap fraction is a lever, stated modestly. Physics only.
