“…To evaluate the RTF effect on the torsatron U-2M plasma behaviour a series of experiments can be performed in the torsatron U-2M with RTF using reduced ~0.3b 0 values only. The restriction occurs because the load-bearing unit of the U-2M magnetic system [1] is not designed for change in the direction of ponderomotive interaction force between a helical coil currents and an additional toroidal magnetic field.…”

“…As is well known in the torsatron U-2M the magnetic system comprises toroidal magnetic field coils [1]. Under normal operating conditions (standard torsatron) the toroidal field coils create the additional toroidal magnetic field B 0 the direction of which coincides with the direction of the toroidal magnetic field component b 0 generated by helical coils on the circular axis of the torus.…”

The torsatron U-2M magnetic system is equipped with 16 additional toroidal magnetic field coils. Under normal operating conditions the toroidal field coils create an additional toroidal magnetic field B 0 the direction of which coincides with the direction of a toroidal magnetic field component b 0 generated by the torsatron helical coils on the circular axis of the torus. In the torsatron with reversed toroidal magnetic field (RTF) the toroidal field coils create an additional toroidal magnetic field B 0r of opposite direction. In this study the conditions for developing the magnetic surface configuration with spatial magnetic axis in the torsatron U-2M with RTF are found out and the magnetic surface configuration properties are investigated.

“…The experiments on ICRF plasma build-up by the W7-X-like antenna were carried out in the U-2M stellarator-type device (see Pankratov et al 2010;Moiseenko et al 2011;Voitsenya et al 2014;Moiseenko et al , 2017a. U-2M (see figure 2) was assembled in the early 1990s (Bykov et al 1990;Pavlichenko 1993), operated briefly and then conserved. It was renewed and put to operation again at the end of 2006 (see Moiseenko et al 2007;Beletskii et al 2008).…”

In support of the ICRF experiments planned on the Wendelstein 7-X (W7-X) stellarator, i.e. fast ion generation, wall conditioning, target plasma production and heating, a first experimental study on plasma production has been made in the Uragan-2M (U-2M) stellarator using W7-X-like two-strap antenna. In all the experiments, antenna monopole phasing was used. The W7-X-like antenna operation with launched radiofrequency power of ~100 kW have been performed in helium (p = (4–14) × 10−2 Pa) with the vacuum vessel walls pre-loaded with hydrogen. Production of plasma with a density higher than 1012 cm−3 was observed near the first harmonic of the hydrogen cyclotron frequency. Operation at first hydrogen harmonic is feasible in W7-X future ICRF experiments.

“…The international community was first informed about the concept of the installation in 1986 [8] at the Conference in Kyoto (Japan). Publications on the installation design, magnetic configuration structure, and estimates of its effect on plasma confinement appeared well after [9][10][11][12]. The most comprehensive description of the magnetic system of the installation can be found in preprint [11].…”

The paper is dedicated to the 50th anniversary of controlled thermonuclear fusion studies performed at the KIPT on the specific stellarator-type experimental installations commonly referred to as “the torsatron”. Detailed data are reported on the operating thermonuclear facility “Uragan-2M”, the research results obtained with it, and also, the prospects for its use as a reactor. The advantages of the torsatron of this type are described, among them being the wide-range parameter variation capability. This is of importance for finding out the regularities related to plasma stability, heating and confinement.
