Abstract
We present the first Thomson scattering (TS) measurements of electron temperature and density
in the lower divertor of the Globus-M2 tokamak. The divertor TS diagnostics is designed for local measurements
of the Te(z, t) in the range of 1–100 eV and ne(z, t) in the range of m–3. Parameters of the
probing Nd:YAG laser are as follows 1064 nm/2 J/100 Hz/3 ns. The probing chord is launched vertically at
R = 24 cm and covers areas of the inner leg, vicinity of separatrix and private flux region. Along probing chord
of 110 mm, 9 spatial points were realized. Advanced filter polychromators were used to analyze Thomson
scattering spectra.
