Description

This paper focuses on a method for measuring the electron temperature (Te) without knowing the transmissivity using Thomson scattering diagnostic with a double-pass scattering system. Application of this method for measuring the anisotropic Te, i.e., the Te in the directions parallel (Te‖‖) and perpendicular (Te⊥) 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 Te ranges, e.g., Te‖‖∼ 3.5Te⊥ at 120° of the scattering angle.
