Abstract

The values of stray environment magnetic fields of the Uragan-2M torsatron have been determined using local magnetic sensors, and also, the electron beam injection in the additional toroidal magnetic field (16 coils, making up 60% to 76% of the total toroidal field). In the stationary toroidal magnetic field, the turns of the electron beam have been visualized by scanning the poloidal vacuum chamber cross-section with a luminescent rod. The measurements have made it possible to determine a decrease in the ratio of stray environment vertical magnetic fields to toroidal-coil magnetic field down to z/BT ≈ 1×10-3 at magnetic fields ВТ = 0.0225 - 0.15 T, and also, to estimate the prospect of the ratio decrease to z/BT ≈ 1×10-4 as the toroidal magnetic field increases up to ВТ ≥ 0.45 Т.
