Description

An X-mode polarized W-band multi-channel correlation reflectometry is installed on the Experimental Advanced Superconducting Tokamak (EAST). The reflectometry with two poloidally spaced receiving antennas works at four different probing frequencies (i.e. 79.2 GHz, 85.2 GHz, 91.8 GHz, 96 GHz), which enables measurement of density fluctuation at 4 (radial) × 2 (poloidal) spatial points. The diagnostics applied to observe density fluctuation and turbulence perpendicular velocity in plasma core on EAST. The detailed description and initial experimental results are presented in this paper.
