WukitchHarvard DataversePhysicsADXhigh field sideRF current driveRF heatingtokamakswaveguidesLaunching lower hybrid (LH) waves from the high field side (HFS) of a tokamak offers significant advantages over low field side (LFS) launch with respect to both wave physics and plasma material interactions (PMI). The higher magnetic field opens the window between wave accessibility and the condition for strong electron Landau damping, allowing LH waves from the HFS to penetrate into the core of a burning plasma, while waves launched from the LFS are restricted to the periphery of the plasma. The lower parallel refractive index (n) of waves launched from the HFS yields a higher current drive efficiency as well. The absence of turbulent heat and particle fluxes on the HFS, particularly in double null configuration, makes it the ideal location to minimize PMI damage to the antenna structure. The quiescent SOL also eliminates the need to couple LH waves across a long distance to the separatrix, as the antenna can be located close to plasma without risking damage to the structure.<a href="http://library.psfc.mit.edu/catalog/reports/2010/15ja/15ja016/abstract.php">PSFC REPORT PSFC/JA-15-16</a><br /><br />This work supported by US Department of Energy cooperative agreement DE-FC0299ER54512.This dataset is made available without information on how it can be used.
