Description

The invention relates to the field of accelerator technology and can be used to accelerate macrobodies, simulate micrometeorites and technogenic particles, and can be used in high-speed impact physics.

Known rail electromagnetic solid state accelerator, consisting of a power housing, parallel electrodes forming an external and internal pair, connected by a jumper, as well as two power sources and two switches. (RF patent No. 2066434, IPC F41B 6/00. Published on September 10, 1996). The disadvantage of this accelerator is the inability to accelerate particles with sizes less than a fraction of a millimeter.

A rail-mounted solid state rail accelerator is also known (RF Patent No. 2027971, IPC F41B 6/00. Published on January 27, 1995), which has similar disadvantages.

The closest is a rail electromagnetic accelerator containing a power casing and the rails located therein and magnetizing coils connected in series with a current source through an armature sliding along the rails. The magnetizing coils are made two-layer to reduce power loads on the rails. (RF patent No. 2418350, IPC Н02К 41/02. Published on 05/10/2011). However, it does not allow accelerating micron particles, although it is more effective due to the presence of magnetization. In addition, the presented prototypes are unable to disperse immediately a group of small particles.

The task is to develop an accelerator free of these shortcomings.

The problem is solved in that in the accelerator containing the power casing and the rails and magnetizing coils in it, connected to the current source, according to the invention, a metal container is added containing micron accelerated particles located in the space between the rails with the possibility of longitudinal movement and providing electrical contact between them.

The invention is illustrated in the drawing, which shows a General view of a rail accelerator of micron particles.

The device includes a power casing 1, rails 2, magnetizing coils 3, a current source 4, a metal container 5, micron accelerated particles 6. The power casing 1 holds the rails 2 contained therein, connected through a magnetization coil 3 to a current source 4, a metal container containing micron accelerated particles 6, located in the space between the rails with the possibility of longitudinal movement and providing electrical contact between them.

The device operates as follows.

The electric circuit formed by the sequential inclusion of the current source 4, magnetization coils 3, a pair of rails 2 and a sliding metal container 5 between them, current flows, creating a magnetic field in the interelectrode space. A magnetic field, interacting with the current flowing through a metal container, causes its acceleration along the rail. The wall thickness of the metal container and the current value are selected so that when the required speed of the container and the micron accelerated particles located in it are reached, the metal container is destroyed by Joule heating and passes into a plasma state. The resulting plasma in the interelectrode space of the railgun, continuing to accelerate under the action of the Lorentz force, gains high speed and takes off from the accelerator, the first relatively micron accelerated particles moving by inertia after the destruction of the container.

The application of the proposed technical solution allows you to accelerate a group of micron-sized particles using a rail accelerator. It should be noted that the particles can be from any refractory material, both conductive and dielectric. In addition, one container may contain particles of different sizes and masses. If the plasma generated during the destruction of the container interferes with the experiment, it can be deflected by a magnetic field that does not affect the trajectory of neutral accelerated particles.
