The πScope workflow engine was used to set up a large number of ray tracing/Fokker- Planck simulations (> 10^4) with parametric scans in the antenna poloidal position and launched parallel refractive index (n||) for both the hybrid and steady state scenarios. Modeling predicts efficient off-axis current drive (1.3 MA for 20 MW launched power) with a peak near ρ of 0.6-0.65 for waves launched from the high field side (HFS). Waves launched from the low field side (LFS) damp at larger radius (ρ > 0.73) with similar efficiency to HFS launch. Stability analysis of the CFETR scenarios favors current drive profiles peaked near the mid-radius, suggesting that HFS launch is preferable due to the current drive location. The effect of wave scattering from density blobs in the edge/scrape-off-layer region was assessed through rotation of the perpendicular wavenumber at the ray origin. Simulations show that this effect can be quite large both in efficiency and damping location, however by adjusting the launched n|| much of the unperturbed performance can be recovered."}}]},{"typeName":"subject","multiple":true,"typeClass":"controlledVocabulary","value":["Physics"]},{"typeName":"keyword","multiple":true,"typeClass":"compound","value":[{"keywordValue":{"typeName":"keywordValue","multiple":false,"typeClass":"primitive","value":"CFETR"}},{"keywordValue":{"typeName":"keywordValue","multiple":false,"typeClass":"primitive","value":"fusion reactor design"}},{"keywordValue":{"typeName":"keywordValue","multiple":false,"typeClass":"primitive","value":"lower hybrid current drive"}},{"keywordValue":{"typeName":"keywordValue","multiple":false,"typeClass":"primitive","value":"non-inductive current drive"}},{"keywordValue":{"typeName":"keywordValue","multiple":false,"typeClass":"primitive","value":"steady state tokamak"}}]},{"typeName":"notesText","multiple":false,"typeClass":"primitive","value":"<a href=\"http://library.psfc.mit.edu/catalog/reports/2020/21ja/21ja016/abstract.php\">PSFC REPORT PSFC/JA-21-16</a><br /><br />This work is supported by US DoE Grant Nos.
