Abstract

The invention discloses a high-speed projectile centrifugal acceleration system and method, including a rotating pump body, a rotating shaft, a rotating blade, a rotating chamber, an accelerator support, a feeding chamber, a feeding pipeline, a discharge port, a discharge pipeline, a target chamber, Molecular pump unit and controller. The rotating shaft is installed on the rotating pump body, and the rotating blade is installed above the rotating shaft, and the rotating shaft and the rotating blade are placed inside the rotating chamber; the feeding chamber is located on the top of the rotating chamber, and is connected to the top of the rotating blade through a feeding pipe; the outlet is set On the side wall of the rotating chamber, the discharge pipe is welded to the discharge port, and the discharge pipe is in the tangential direction of the rotating chamber; the molecular pump unit is connected to the rotating pump body; the controller provides power for the rotating pump body and controls the rotation with frequency conversion Shaft speed, and display the rotation speed in real time. In the present invention, the rotating pump body and the rotating shaft of the turbomolecular pump are used to provide the rotating blades with a rotating speed of up to 40000-90000 revolutions per minute, and finally the projectiles are thrown out through the discharge port and the discharge pipe in the tangential direction of the rotating chamber to achieve 500 rounds of projectiles. ‑1000m / s high-speed injection solves the problem of high-speed projectile injection in fusion devices.

Description

technical field [0001] The invention relates to the field of fusion reactors, and mainly relates to a high-speed projectile centrifugal acceleration system and method. Background technique [0002] In fusion devices, high-speed projectile injection is widely used in plasma feeding and impurity projectile injection to realize the fields of plasma feeding, rupture protection, boundary local mode control and impurity transport research. In particular, the injection technology of frozen hydrogen isotope projectiles is used to realize the feeding of the plasma core and improve the feeding efficiency of the plasma. [0003] At present, many fusion devices at home and abroad are equipped with different pellet injection systems, such as EAST, HL-2A, JET, ASDEX-U and DIII-D, etc. Among them, the injection of frozen hydrogen isotope projectiles is a method of condensing gas into solid projectiles through low-temperature technology, and injecting them into the fusion device by means o...
