- W2885671339 abstract "Efficient lower hybrid current drive (LHCD) is demonstrated at densities up to n¯e≈1.5×1020 m−3 in diverted plasmas on the Alcator C-Mod tokamak by operating at increased plasma current—and therefore reduced Greenwald density fraction. This density exceeds the nominal “LH density limit” at n¯e≈1.0×1020 m−3 reported previously, above which an anomalous loss of current drive efficiency was observed. The recovery of current drive efficiency to a level consistent with engineering scalings is correlated with a reduction in density shoulders and turbulence levels in the far scrape-off layer. Concurrently, rf wave interaction with the edge and/or scrape-off-layer plasma is reduced, as indicated by a minimal broadening of the wave frequency spectrum measured at the plasma edge. These results have important implications for sustaining steady-state tokamak operation and indicate a pathway forward for implementing efficient LHCD in a reactor.Received 9 April 2018Revised 22 June 2018DOI:https://doi.org/10.1103/PhysRevLett.121.055001© 2018 American Physical SocietyPhysics Subject Headings (PhySH)Research AreasCurrent driveWave-wave, wave-particle interactionsPhysical SystemsTokamaksTechniquesFokker-Planck & Vlasov modelRadio-frequency & microwave plasma measurementsX-ray & gamma ray plasma measurementsPlasma Physics" @default.
