It is shown that this off-axis LH current drive can be used to create discharges with non-monotonic profiles of the current density and reversed shear. An advanced tokamak operating regime near the ideal no-wall [beta]-limit is described for C-Mod, where about 70% of the current is driven through the bootstrap effect. The LH power is coupled to C-Mod through a waveguide launcher consisting of four rows (vertically) with 24 guides per row (toroidally). A detailed description of the LH launcher fabrication is given in this paper along with initial operation results.
