‎FY2019 NSTX-U Facility and Diagnostic Milestones‎

Diagnostic Milestone D(19-1): Install and commission high kq diagnostic system (September 2019)

Description: To measure electron-scale micro-turbulence in NSTX-U, the 280 GHz high-k tangential scattering system of NSTX will be replaced by a 693 GHz poloidal scattering system being developed by UC Davis for NSTX-U, thereby considerably enhancing planned turbulence physics studies by providing a measurement of the kθ-spectrum of ETG turbulence. Initial high-k scattering data will be obtained pending resumption of NSTX-U plasma operations.
