  • Descrição: This paper focuses on a method for measuring the electron temperature ( T e ) without knowing the transmissivity using Thomson scattering diagnostic with a double-pass scattering system. Application of this method for measuring the anisotropic T e , i.e., the T e in the directions parallel ( T e|| ) and perpendicular ( T e⊥ ) to the magnetic field, is proposed. Simulations based on the designed parameters for a JT-60SA indicate the feasibility of the measurements except in certain T e ranges, e.g., T e|| ∼ 3.5 T e⊥ at 120° of the scattering angle.
