![]() ![]() ![]() ![]() ![]() Verification of the GLOBSYS code using the data from the aforementioned spherical tokamaks is the basis for the prediction of parameters of the next step of Globus-M program. This time is compared with two technical restrictions, which are connected with the times of toroidal field coil heating and poloidal flux capacity. The condition of reaching the plasma quasistationary regime (or the time of establishment of quasistationary plasma profiles τ L/R) is estimated for NSTX, NSTX-U, MAST, MAST-U and ST40 discharges. For increasing B t0, more optimistic predicted plasma parameters are obtained for the Globus-2021 and NSTX scalings in comparison with the ITER confinement scaling. Simulations with other confinement scalings (Globus-2021, NSTX scalings) give good agreement with plasma parameters for the toroidal field B t0 ~ 0.5 T. The best agreement is observed if ITER confinement scaling is used for energy confinement time with the enhancement factor H y, 2 = 1-1.2. As a whole, there is good agreement between simulations and plasma parameters at the discharge plateau. In this paper, the verification of the code using the achieved and predicted data from the installations NSTX, NSTX-U, MAST, MAST-U, and ST40 is given. In, preliminary selection of correlations which connect physical and technical parameters was made. The word globe comes from the Latin word globus, meaning sphere. The GLOBSYS code was developed for analysis and prediction of parameters of the Globus-M2 tokamak and its modifications. Typically, it will also divide the celestial sphere into constellations. ![]()
