“…Port 2 is shifted by 180 • in the toroidal direction from the cross section, where temperature and density were measured by Thomson scattering. Electron temperature and density profiles prior to and after jet injection into the Globus-M target plasma were measured by a high repetition rate Thomson scattering diagnostic [48,49]. The closest in time measurements were carried out at a delay of 35 µs between jet injection and laser shot, reliable profile measurements were carried out at the delay of 50 µs.…”

“…For these particular experiments important measurements were provided by the 3 vertical chord 1 mm microwave interferometer and 12 channel neutral particle analyzer (NPA) with a tunable energy range (0.3-20 keV). The usage of two advanced diagnostics: multipulse Thomson scattering [6] and 32-chord SXR camera [7], used in cooperation with the extended array of toroidal and poloidal Mirnov probes allowed us to fundamentally improve our measuring capability.…”

“…2). В диагностике ТР на токамаке Глобус-М [9] основным зондирующим источником является Nd:Glass-лазер, позволяющий формировать последовательность импульсов (до 20 импульсов) с частотой до 3 кГц, со средней энергией 2 Дж и длительностью ~30-50 нс на длине волны генерации 1055 нм [10]. В настоящее время для диагностирования плазмы на токамаке Глобус-М вводится в эксплуатацию лазер Nd:YAG 1064 нм/100 Гц/2 Дж с шириной импульса на полувысоте 4 нс.…”
