description: This work is devoted to multi-chord measurements of bremsstrahlung at the Globus-M2 tokamak. The following goals were achieved: - introduction of new ADC modules with a sampling rate of 500 kHz for recording Thomson scatter diagnostic signals - measurements of the bremsstrahlung power in discharges with a field of 0.8 T and a current of 400 kA with ohmic heating and additional heating using neutral injection - development of an algorithm for calculating Zef f from the Thomson bremsstrahlung power scattering system measured with polychromators and the Te and ne profiles The work was perfomed accessing Unique Scientific Facility "Globus-M2 spherical tokamak"Ioffe Institute of Physics and Technology. The main goal is to obtain an effective charge profile at the Globus-M2 facility.
