description: The work is devoted to the modeling of High Field Side High Density (HFSHD) mode and divertor plasma detachment. In the first part of the work the formation of HFSHD region in Globus-M2 tokamak using the hydrodynamic part of SOLPS-ITER code â B2.5, is discussed. The formation leads to divertor targets asymmetry and the HFSHD spot is easily noticeable on the scale of small device. It is shown that the spot formation is caused by the drift in crossed electric and magnetic fields. The dependence of HFS poloidal electric field sign and, consequently, radial drift fluxes on the discharge density is discussed. It is demonstrated that the HFS poloidal electric field is the key element in the formation of HFSD regime in Globus-M2 tokamak. In the second part of the work a comparison of the experiment with nitrogen seeding on Globus-M2 tokamak with the results of modeling by hydrodynamic part of the SOLPS-ITER â B2.5 code, was made. Reduction of heat flows to divertor plates is one of the most urgent problem in devices with high power and a relatively long pulse duration since in such devices the density of power flows to divertor plates should not exceed the critical value , however, the discharge power of the Globus-M2 tokamak was increased after a twofold increase in the toroidal magnetic field [8], and large particle and energy flows became a problem for material surfaces facing the plasma. The work shows a significant decrease in heat flows to divertor plates and the transition to full and partial detachment mode for the lower inner and outer targets with negligibly small impurities content in the retention zone.
