“…A prototype of the source was tested in GOL-3 in a simulation experiment that reproduced the magnetic configuration of GOL-NB except for the central trap. Transport of the low-temperature plasma stream through the required distance with n max > 10 20 m −3 was demonstrated [79]. The mirror ratio with respect to the arc source anode was varied in the range from 5 to 60.…”

Physical and technical details of the GOL-NB project are presented. GOL-NB is a medium-scale multiple-mirror trap that is under development in the Budker Institute, Novosibirsk, Russia. This device will be created in several years as a deep conversion of the existing GOL-3 facility. It will consist of a central trap with two 0.75 MW neutral beams, two multiple-mirror solenoids, two expander tanks and a plasma gun that creates the start plasma. The central trap with the neutral beam injection-heated plasma is a compact gas-dynamic system. The multiple-mirror sections should decrease the power and particle losses along the magnetic field. The confinement improvement factor depends on plasma parameters and on the magnetic configuration in the multiple mirrors. The main physical task of GOL-NB is direct demonstration of the performance of multiple-mirror sections that will change equilibrium plasma parameters in the central trap. In this paper we discuss results of the scenario modeling and progress in the hardware.

“…The initial commissioning will start in GOL-NB-1 configuration [39] without the central trap that will enable earlier start of experiments. Design of GOL-NB allows further advances to a more complex scenarios and higher plasma parameters with additional heating systems if the corresponding proposals will be supported.…”

Abstract.A fusion reactor concept on the basis of a linear trap is developing in BINP. These studies incorporate multiple-mirror sections which should reduce significantly longitudinal plasma losses from a confinement zone. In the paper, physics on the multiple-mirror confinement relevant to plasma behavior at reactor conditions will be discussed. Basic results were received in the GOL-3 multiple-mirror trap in which plasma of 10 21 m -3 density was heated by a highpower electron beam up to 2 -4 keV temperature. The key milestones were: the demonstration of effective plasma heating by the electron beam due to collective effects, the achievement of theoretically predicted level of energy confinement time under optimal conditions, and finally, the discovery of a bounce instability that improves longitudinal confinement. Direct demonstration of a confinement improvement by multi-mirror sections in the magnetic configuration relevant to the reactor one will be done in the GOL-NB facility that will be created in BINP. In addition, a new plasma device SMOLA with a helical multiple-mirror magnetic field for an active confinement control is discussed.

“…Up to now, such target plasma is created by plasma guns, mounted on the ends of a trap. In particular, GDT facility, operating in Budker INP, use this approach [7,8], and it is planned to apply on the novel facilities GOL-NB [9] and SMOLA [10][11], that is now under construction. At the same time, arc plasma guns have several disadvantages, which prevent their use in next generation of linear fusion facilities.…”
