| 4 | Influence of the safety factor profile on the particle and heat transport in the Globus-M spherical tokamak显示文摘The advanced tokamak scenario is a promising operation scenario for ITER and fusion neutron sources.In this scenario the minimum value of the safety factor in the center of the plasma exceeds unity.In the compact spherical tokamak Globus-M,the formation of such conditions is possible with neutral beam injection at the current ramp-up phase.Due to the slower diffusion of current inside the plasma,a zone is formed with reduced heat and particle transport across the magnetic field,which affects the temperature and density profiles of the plasma.This leads to the peaked density profile formation and improvement of the energy confinement time.To achieve a high fraction of the bootstrap current,it is necessary to increase the plasma pressure.At the same time,the maximum allowable pressure is limited to the normalized beta limit. | A YU TELNOVA G S KURSKIEV E O KISELEV N N BAKHAREV V K GUSEV N A KHROMOV S YU MEDVEDEV V B MIINAEV I V MIROSHNIKOV M I PATROV Yu V PETROV N V SAKHAROV A D SLADKOMEDOVA P B SHCHEGOLEV V V SOLOKHA V A TOKAREV S YU TOLSTYAKOV E A TUKHMENEVA | 2019 | Plasma Science and Technology2019，21，11： | 0 |
