An Electron Cyclotron Emission Imaging (ECEI) System for HL-2A

POSTER

Abstract

A high resolution Electron Cyclotron Emission Imaging (ECEI) system is under development for the HL-2A tokamak in Chengdu, China. The diagnostic instrument has a tunable RF range of 75 to 135 GHz, and will generate 192 channel (24 vertical by 16 radial) images of the 2nd harmonic X-mode radiation from the HL-2A plasma, and is equipped with both vertical and horizontal zoom capabilities. Fabrication and characterization are scheduled to be completed by November 2012, with installation and commissioning on HL-2A to take place in early 2013. Details regarding the optical and electronic performance of the system will be presented.
