Noninductive plasma initiation and startup in the DIII-D tokamak. Jackson, G., L., Humphreys, D., A., Hyatt, A., W., Lohr, J., M., Luce, T., C., & Yu, J., H. Nuclear Fusion, 51(8):83015, 2011. Paper Website abstract bibtex Noninductive plasma startup with second harmonic electron cyclotron
heating has been studied in DIII-D. Plasma currents up to 33鈥塳A have
been obtained in this phase. The maximum current obtained was primarily
limited by the experimental time and does not necessarily represent
the highest achievable current. The dominant physical mechanism for
the observed current is the Pfirsch鈥揝chl眉ter current on open field
lines. Closed flux surfaces have been observed, but in a rather limited
region, compared with previous experiments in spherical tokamaks.
This method of plasma initiation and initial current ramp might be
used in future burning plasma devices in conjunction with other current
drive techniques to provide a fully noninductive startup.
