Abstract
In this article, we report on the hardware and software of an eight-channel , high-resolution, spectroscopic diagnostic system that has been built for the TJ-II flexible heliac. This system is currently being used on TJ-II to measure impurity ion temperature and poloidal rotation using passive emissi on spectroscopy. The principal features of the diagnostic include independe nt focusing of its channels, high sensitivity for performing Doppler measur ements in low-density ECR-heated plasmas, as well as a flexible and fast in -house-developed software program for performing integrated data reduction and analysis.
