Position of the point of performing measurements in the plasma vertical cross-section depends on the beam energy and angle of its entrance into the plasma. The variation of these two parameters makes it possible to construct a two-dimensional (2D) detector grid, which covers the domain of possible measurements. The measurement results obtained in the detector grid points provide for constructing 2D distributions of plasma parameters. For the OH and ECRH stages of the T-10 tokamak shots, 2D distributions of the plasma electric potential are presented for the regime with the on-axis magnetic field of Bt = 2.2 T, plasma current of Ipl = 230 kA, line-average density of ne ≈ 1.1 × 1019 m–3 and off-axis ECRH power of PECRH = 1.7 MW.</p></abstract><trans-abstract xml:lang="ru"><p id="idm45257551616144">Зондирование плазмы пучком тяжелых ионов (ЗПТИ) – уникальная диагностика, позволяющая измерять электрический потенциал высокотемпературной плазмы φ и его колебания \(\tilde {\varphi }\), а также колебания плотности \({{\tilde {n}}_{e}}\) и полоидального магнитного поля \({{\tilde {B}}_{{pol}}}\) плазмы. Положение точки измерения в вертикальном сечении плазмы зависит от энергии пучка и угла его влета в плазму. Вариация этих двух параметров позволяет построить двумерную детекторную сетку – область возможных измерений. Результат измерений по детекторной сетке представляет собой двумерное распределение параметра плазмы.
