Angara-5-1

The experimental complex "Angara-5-1" was created in the OFTP JSC "State Research Center of the Russian Federation TRINITI" in 1984.

Since its inception and up to the present time, "Angara-5-1" is one of the largest on the continent installation for research on the physics of fast self-compressed discharges super-terawatt power, dynamics of emitting plasma of multiply charged ions, the problem of inertial controlled fusion.

The complex is an energy base for fundamental research on the equations of state of matter with a high energy density, shock waves, and X-ray spectroscopy.

The complex conducts research on the electrophysics of generators of super-powerful electric pulses, and develops physical schemes of powerful pulsed sources of X-ray and neutron radiation.

The energy of the complex is provided by a pulse electric power generator, which consists of 8 modular generators connected in parallel using a high-voltage synchronization system.

The reactor chamber of the facility allows experiments with physical activity in a wide range of initial parameters.

In 2000, for the first time at the complex, a double liner scheme was proposed and studied, which under the name "dynamic holraum" has now received worldwide recognition as a driver for initiating a thermonuclear microexplosion by a soft X-ray pulse.

In experiments with a deuterium Z-pinch, a world record of the neutron yield for pinches was obtained. For the creation of the "Angara-5-1" installation, for carrying out a complex of research on the physics of emitting plasma of multiply charged ions, the team of authors was awarded the State Prize of the Russian Federation in Science and Technology for 1997.
