摘要：
Results of the investigation of ion heat transport processes in the T-10 tokamak are presented. Experiments are carried out in a wide range of ohmic plasma parameters (n(e), I-pl, and Z(eff)). Variation of the effective ionic charge from 3.5-4 to 1 is performed by inserting a lithium limiter. Measurements of the ion and electron temperature and density profiles are presented. The power balance approach is used for the determination of the ion heat conductivity. Modeling is performed using the ASTRA transport code. It is shown that in ohmic plasmas in the region of r/a similar to 0.5, ion heat conductivity is close to the neoclassical values, which are calculated using the NCLASS code.
