Description

The invention relates to the field of particle acceleration and can be used to supply thermo nuclear fuel pellets to thermo nuclear reactor plasma.

The aim of the invention is to increase the reliability and expand the functionality of the device.

FIG. Figures 1 and 2 are shown in two projections of the schematic diagram of the device.

The device comprises a housing 1 with a shaper 2 tablets 3. The housing is connected by pipe 4 with a chamber of 5 s, plasma 6 of a nuclear reactor. Part of the pipe 4 is made in the form of a barrel 7. A centrifugal tablet thrower is installed in the housing 1, which consists of a rotor 8 with a drive 9. An accelerating channel 10 with an inlet 11 is made in the rotor. The seal 12 is located on the shaft 13. The laser 14 is connected by a nozzle 15 at an acute angle C with a barrel 7. The laser is equipped with a launch unit 16. The laser beam is focused in the barrel 7 on the flight path of the tablet 3. Before the focus 17 of the laser beam, there is a speed sensor 18, KOTOpi is connected to the laser launch unit. Sensor 18 contains light source 19.

The device works as follows.

By means of the drive 9, the rotor 8 of the centrifugal thrower is accelerated to a predetermined rotational speed. In the shaper 2, fuel cells are formed from a gas mixture of fuel. At cryogenic temperatures, solid fuel cells 3 with a diameter of about 2 mm are formed. From the shapes of the world tablets, they are fed into the opening 11 of the accelerating channel 10. The feeding of the tablets is synchronized with the possibility of their capture by the accelerating channel. Under the action of centrifugal forces, the tablet accelerates in the accelerating channel and is thrown out and it on the periphery of the rotor into the pipeline 4. In the course of movement through the pipeline, the tablet interrupts the light beam from the source 19 incident on the photosensor. The current pulse from the speed sensor 1 is fed to the laser starting unit 16. Pass a portion of the pipeline, the tablet enters the barrel in which it moves like a piston in a cylinder.

The laser focus tablet 17 The launcher includes a laser and the beam from it hits the end of the tablet. Under the action of the heat flux concentrated at the end of the tablet, a microexplosion occurs, accompanied by the release of the evaporating tablet material and the formation of a jet of gases, which gives the tablet an additional velocity impulse. A tablet with a higher speed continues to move further along the pipeline and into the plasma chamber 5. After the pellet burns in the plasma of the thermo-nuclear reactor, the tablet feeding process is repeated.

The tablet acceleration process is carried out in vacuum without using gas from an external pressure source, which greatly simplifies and reduces the load on the vacuum pumping system. The process of switching on the laser is pulsed. The duration and energy of the laser pulse is determined by the thermophysical parameters of the tablet material and is matched with the magnitude of the additional velocity pulse and the mass of the non-evaporated part of the tablet, which is necessary for the power processes in the plasma.

The centrifugal injector serves to obtain the initial velocity of the tablets. A further increase in speed is produced by pulsing the laser radiation on the end of the tablet. Such phased acceleration of tablets provides the most efficient use of each acceleration method, operating in its speed range and expanding the functionality of the device. Moreover, due to the high initial velocity of the tablet after the centrifugal thrower, it is precisely the laser that is used. the most high-speed and contactless way of energy transportation, provides the required increase in speed - 1 tablet. The laser allows you to concentrate the necessary energy pulse in focus, commensurate with the diameter of the tablet, which makes it possible to produce local heating and evaporation of the tablet, while simultaneously using the material of the tablet to create a jet stream of gases.
