Abstract:
The prototype phased-array antenna system has been developed to control the incident angle and polarization to conduct the Electron Bernstein Wave Heating and Current Drive (EBWH/CD) experiments on the QUEST. The two orthogonal fields measured at the low power level were in excellent agreement with those evaluated by a developed Kirchhoff code. The elliptical polarization in two orthogonal fields can be controlled to excite pure O-mode in the oblique injection. The non-inductive plasma current of 10 kA was ramped up and sustained for 0.7 s. The phased-array antenna system for the reflectometry and the EBW radiometry has been also develoloped concerning the EBWH/CD experiments, and was confirmed to work well in the low power tests.
