A new spectroscopic diagnostic on the National Spherical Torus Experiment (NSTX) measures the velocity distribution of ions in the plasma edge with both poloidal and toroidal views. An anisotropic ion temperature is measured during the presence of high power High Harmonic Fast Wave (HHFW) Radio Frequency (RF) heating in helium plasmas, with the poloidal ion temperature roughly twice the toroidal ion temperature. Moreover, the measured spectral distribution suggests that two populations are present and have temperatures of 500 eV and 50 eV with rotation velocities of -50 km/s and -10 km/s, respectively. This bi-modal distribution is observed in both the toroidal and poloidal views (in both He + and C 2+ ions), and is well correlated with the period of RF power application to the plasma. The temperature of the hot edge ions is observed to increase with the applied RF power, which was scanned between 0 and 4.3 MW. The ion heating mechanism is likely to be Ion Bernstein Waves (IBW) from nonlinear decay of the launched HHFW. Radio frequency (RF) waves are important tools in studying and producing magnetically confined, fusion-grade plasmas such as those in the National Sperical Torus Experiment (NSTX)[1]. Depending on the phase of the launched wave, RF power can be used to tailor either the current-density profile (current drive) or the temperature profile (plasma heating). Moreover, the ef-ficiency of launching waves into the plasma relies on the plasma-antenna coupling. The plasma environment di-rectly in front of the antenna can itself be affected by the input of high power RF waves. The High Harmonic Fast Wave (HHFW) launched by the NSTX antenna is expected (and observed) to heat core electrons, but for the plasma parameters discussed here, the plasma ions should be unaffected[2]. A new spectroscopic diagnostic with both toroidal and poloidal views has been implemented in the edge of the NSTX. This edge rotation diagnostic (ERD)[3] was de-signed to measure the velocity and temperature of ions. The ERD measures the intrinsic emission of light from the plasma edge. The intersection of the diagnostic sight-line with the intrinsic emission shell provides the localiza-tion of the measurement. There are 7 toroidally directed views and 6 poloidally directed views of the outboard plasma edge. The poloidal view is ∼ 20 cm (toroidally) from the RF antenna, and the toroidal view is ∼ 2 m away. The sightlines are nearly tangent to the flux sur-faces. The C 2+ triplet near 465 A and the He + line at 468 A are measured. In the results presented here, helium is the bulk "working" ion of the discharge.
