1. Performance analysis of beam emission spectroscopy
In fusion plasmas, turbulent transport is believed to be one of the largest obstacles, since it enhances the energy loss and hampers the fusion relevant core plasma production. In order to analyze physical characteristics of turbulence, the beam emission spectroscopy diagnostic system has been installed in LHD. We will conduct a yearly performance analysis of the large-diameter filter spectroscopy system.
