Description

The invention relates to plasma technology, and more specifically, to devices for insertion into plasma traps and can be used in the development and creation of large-scale nuclear installations.

The purpose of the invention is to more effectively maintain the initial distribution of plasma density in a thermo-nuclear installation.

FIG. 1 shows the proposed ycTpofjcTBo (the plates of the package are made in the form of a rectangle); in Fig.2 - the same, (the plate of the package is made in the form of a circle); FIG. 3 is the same, top view.

The plate pack 1 is located in a metal case 2. Cryostats 3, with solid fuel 4 in them, communicate with channels 5 and 6. Outside, the cryostats 3 and case 2 are filled with heat exchangers 7 in the form of a tubular coil through which liquid helium is pumped . In the upper part of the cryostats are located 8 rt 9 pistons, with the help of which solid fuel is fed to channels 5 and 6.

Plates 1 and body 2 have three equidistant holes, located on the same axis. In the embodiment of the device proposed (Fig. 2), the holes are equidistant from the axis of rotation of the disk and are located at the vertices of an isosceles triangle. The openings form channels 5 and 6 for introducing fuel and channel 10 for accelerating solid fuel pellets. Channel 10 is associated with an accelerating device AND, for example, a pneumatic gun. In the package, at least two of the plates have different thicknesses. The plates and the hole diameter are chosen such that when they are filled with solid fuel, the number of deuterium or tritium atoms is 5–20% of the number of plasma ions of the nuclear installation. The ratio of the plate thicknesses in the package is determined by the plasma parameters in the installation: temperature and density and their distributions along the plasma volume cross section.

The device works as follows. When liquid gels are supplied to the heat exchangers 7, the case 2 and the cryostat 3 are cooled when the operating temperature (5 ° K) is reached in the Cryostats 3 is set to fuel 4, for example,

terium or tritium. With the help of the piston 8, the solid fuel fills the channel 5, while the channel 6 remains free. Then the top plate of the package 1 is moved to the right by a length equal to the distance between channels 5 and 10, while this hole of the top plate filled with solid Fuel is installed in the accelerating channel 10, and the hole previously communicating with the channel 10 is aligned with the channel 6. The accelerating device is turned on, the accelerating pulse of which is selected for -. previously such that the tablet of the smallest thickness (and therefore the smallest mass, t) receives the velocity U required for the passage to the central region of the thermal installation, and the tablet of solid fuel is fired into the plasma volume. (The value of P m and. During operation is not possible. At the same time as the accelerator is turned on, piston 9 begins to squeeze solid fuel into channel 6. Then, one after another, the remaining plates of the bag move to the right and also sequentially injected into channel 10, plates transferred by the plates, which were previously filled in channel 5. During this time, the f channel is filled with solid topshi. Since the tablets formed on the plates whose thickness is different, they have p zlichnymi masses. Hence thicker tablets are injected into the plasma volume at a slower rate moving speed Sh Reduction

tablets in high-temperature plasma leads to a more than linear age; its first ablation rate, therefore, larger tablets evaporate more efficiently. Therefore, tablets injected from plates of different thickness deliver fuel to different areas of the plasma volume, which contributes to a more efficient maintenance of the initial plasma density distribution in the thermal installation.

After the last tablet has been fired, channel 6 is completely filled with fuel and the device returns to its original position with the only difference that now all the plates are moved to the right and channel 6 is filled with fuel, and channel 5 is free,

3 1

Reality continues to work in reverse order and so on.

The difference of the device is that the cage is assembled from round discs 1 and the fuel supply from channels 5 and 6 to channel 10 is carried out by rotating each of the disks to the right and right around its axis by an angle equal to the angular distance between the channels 5 and 10 or 6 and 10.
