The Thomson Scattering diagnostic at TJ-II

The high-resolution Thomson Scattering system (located in sector D2) provides electron temperature, density, and pressure profiles at a single time in the discharge. [1] [2] [3] [4] [5] The number of data points along the profiles can vary from shot to shot depending on magnetic configuration, the shape of actual plasma, the influence of stray light level on data quality, etc. The estimated spatial resolution of diagnostic is approximately 2.4 mm. Signal names in the TJ-II database: 'PerfilRho_', 'PerfilTe_', 'PerfildTe_', 'PerfilNe_', 'PerfildNe_', 'PerfilPe_', 'PerfildPe_'.
