description: This work is devoted to checking the operability of the test configuration of the new Thomson scattering diagnostics installed on the TUMAN-3M tokamak and optimizing the scattered radiation collection system. Methods of relative and absolute calibrations of Thomson scattering diagnostics, a method for restoring the values of electron temperature and plasma density using Thomson diagnostics are described. According to measurements of the electron temperature in a series of repetitive discharges, the evolution of the electron temperature in various modes of operation of the tokamak in the central plasma region and previously inaccessible to measurement of the wall plasma region, characterized by a low electron density, and, accordingly, a low intensity of scattered radiation. The possibility of optimizing the system of collecting scattered radiation is evaluated. It is planned to install an optimal lens that collects 70% more light than the current one and has a better spatial resolution. The results of the work can be used to perform absolute calibration and, in the future, to restore the local plasma concentration value.
