The Russian Nuclear Physics Institute is entering the testing phase in the field of plasma for the use of a magnetic field with screw symmetry, which will allow controlling the rotation of the plasma to suppress the longitudinal losses of the plasma from an open trap. To test this concept, an experimental RESIN installation (a Spiral magnetic open trap) was developed and built.
The Institute of Nuclear Physics of the Siberian Branch of the USSR Academy of Sciences was established in accordance with the resolution of the Council of Ministers of the USSR in May 1958 on the basis of the Laboratory of New Methods of Acceleration, headed by G.I. Budker, of the Institute of Atomic Energy, directed by I.V. Kurchatov. Since 2015, the Institute has been headed by Academician Pavel Logachev.
At present, Budker Institute of Nuclear Physics of SB RAS is the largest academic institute of the Russian Federation, and one of the world’s leading research centers in the field of elementary particle physics, accelerator physics and technology, synchrotron radiation sources, free electron lasers, high-temperature plasma physics, and controlled thermonuclear fusion.
Originally, the idea first surfaced in the Nuclear Physics Institute in 2012. It was based on “tricking” the substance to create such a configuration of a stationary magnetic field that the plasma “seemed” that it was moving to the center.
Open traps differ in that the magnetic field lines are not closed in them and the plasma is held in the middle. However, at the ends of installations, along power lines, plasma can flow out, and the task is to reduce this flow. To reduce losses, magnetic plugs are placed at the ends of the traps, that is, they dramatically increase the strength of the magnetic field. The GDL (gas-dynamic trap) attempts to narrow the “necks” of the bottle from which the plasma flows, but it is impossible to completely avoid losses.
The GOL (corrugated trap) has several magnetic plugs on each side. In such a design, the plasma seems to “rub” against the “corrugation” of the magnetic field. Due to the friction force, the flow rate becomes lower than the sound one, which means that there will be less loss. Since the distance between the traffic jams is clearly defined, they can’t make them infinitely close, but they can increase the length of the multi-stop sections. In order to reduce the rate of plasma outflow, the multi-test sections should be literally moved to the center of the installation. In this case, the plasma itself will “stand,” and along it “fly” magnetic plugs, creating a force of friction and dragging the substance along with it.
The idea of moving traffic jams arose simultaneously with the idea of the most multi-test trap, but then the task was considered impossible and unprofitable; to create such a “running” field, you need incredible power. (Source: Scientist Alexey Arakcheev)
For this new experiment, the required supplies are: one screw magnetic plug, the node where the plasma is created, its receiver, and an expander that pulls the substance into the magnetic field. Now they have started to “feel” the plasma and see how its characteristics change in different modes of operation. To confirm the theoretical calculations, a stable improvement is needed in the characteristics of the plasma in a device with a screw magnetic plug compared to a conventional one.
One of the main applications is that screw traps increase the plasma flow rate of 100 km/s. this is a basic condition of the engines of the spacecraft transporting satellites from geosynchronous orbit, for example, to the orbit of the moon.
A geostationary orbit, also referred to as a geosynchronous equatorial orbit, is a circular geosynchronous orbit 35,786 kilometres above Earth’s equator and following the direction of Earth’s rotation.
