Abstract:
Realization of high performance of EXL-50U plasma rely on neutral beam heating sensitively, which means the beam ions should have a good confinement. The paper gives unacceptable ripple loss results, both on beam ion loss fraction and localized heat load, based on equilibrium, beam ion distribution and ripple data in integrated modeling. The optimization method consist of lower the ripple perturbation amplitude, increase the plasma current and optimization of NBI injection geometry. Calculation results indicate the plasma region should move to high field side and FI to lower the ripple field, increase the Ip above 600kA, beam ion loss fraction can be lower to 3-4%, heat load down to one magnitude. The paper conclude the method of fast ion ripple loss evaluation, including phase space and full calculation within one slowing down time. Also in the paper have other direction of how to lower ripple loss when design a new facility, this will help for integrated modeling and plasma operation.
