Title: Development of Real-Time Software for Thomson Scattering Analysis at NSTX-U

Abstract

The Thomson Scattering Diagnostic on the National Spherical Tokamak eXperiment Upgrade (NSTX-U) has been an essential system for many operational campaigns due to its function of measuring plasma electron density and temperature. Constructive feedback to improve the next plasma discharge, however, has been limited because of in-between shots analysis. Plasma Control, therefore, desires a diagnostic system that is real-time capable. This contribution presents the development of software that demonstrates the feasibility of a real-time Thomson Scattering diagnostic system for NSTX-U. The developed software is able to evaluate the electron temperature and density within 2.5ms.
