High Field Side Lower Hybrid Current Drive Simulations for Off- axis Current Drive in DIII-D

Autor: Wukitch S.J., Shiraiwa S., Wallace G.M., Bonoli P.T., Holcomb C., Pinsker R.I.

Publikováno v: EPJ Web of Conferences, Vol 157, p 02012 (2017)

Efficient off-axis current drive scalable to reactors is a key enabling technology for developing economical, steady state tokamak. Previous studies have focussed on high field side (HFS) launch of lower hybrid current drive (LHCD) in double null con

ICRF mode conversion in three-ion species heating experiment and in flow drive experiment on the Alcator C-Mod tokamak

Autor: Lin Y., Wukitch S.J., Edlund E., Ennever P., Hubbard A. E., Porkolab M., Rice J., Wright J.

Publikováno v: EPJ Web of Conferences, Vol 157, p 03030 (2017)

In recent three-ion species (majority D and H plus a trace level of 3He) ICRF heating experiments on Alcator C-Mod, double mode conversion on both sides of the 3He cyclotron resonance has been observed using the phase contrast imaging (PCI) system. T

LHCD during current ramp experiments on Alcator C-Mod

Autor: Wallace G.M., Poli F., Chilenski M.A., Hughes J.W., Mumgaard R.T., Scott S.D., Shiraiwa S., Wukitch S.J.

Publikováno v: EPJ Web of Conferences, Vol 157, p 03063 (2017)

The lower hybrid current drive (LHCD) system on Alcator C-Mod is capable of sustaining fully non-inductive discharges for multiple current relaxation times (τcr ∼ 200 ms) at line averaged densities in the range of 5x1019 m-3. Some of these non-ind
