An electrostatic deflection plate for injection and extraction of charged particles in a cooling storage ring

Abstract

The invention relates to the technical field of heavy ion accelerators, in particular to an electrostatic deflection plate used for injecting and extracting charged particles in a cooling storage ring. It is characterized in that it includes a vacuum chamber, and the outside of the vacuum chamber is provided with a vacuum transmission mechanism, a compensation electrode connection part and a high-voltage input part, and the anode frame and a high-voltage electrode are correspondingly provided in the vacuum chamber, and the anode frame is fixed in the vacuum through a transition connection. On the transmission mechanism, the anode frame is provided with a cutting plate and a measuring rod. The high-voltage electrode is fixed on the first electrode support and the second electrode support by screws, and the third support bolt is fixed on the insulating support by screws. The insulating support and the vacuum The transmission shaft of the transmission mechanism is connected. It has reasonable structure, simple processing, high yield, convenient disassembly and replacement, and low cost of spare parts; effectively improves the transmission efficiency, realizes the adjustment of the position of the high-voltage electrode and the cutting plate perpendicular to the direction of the beam in the plane, and ensures a high transmission process. Excellent movement repeatability and linear displacement accuracy.

Description

technical field [0001] The invention relates to the technical field of heavy ion accelerators, in particular to an electrostatic deflection plate used for injecting and extracting charged particles in a cooling storage ring. Background technique [0002] Lanzhou Heavy Ion Accelerator Cooling Storage Ring (HIRFL-CSR) is one of the national "Ninth Five-Year Plan" major scientific engineering projects. It consists of the main ring CSRm and the experimental ring CSRe, and is mainly used for the experimental research of medium and high energy heavy ions. In the injection extraction system, the design of the electrostatic deflection plate will play a key role in whether the CSR can extract the beam and operate efficiently. [0003] The entrance thickness of the traditional electrostatic deflection plate high-voltage electrode and cutting plate cannot reach 0.1mm. If a plate with a thickness of 0.1mm is used as the cutting plate, the cutting plate will be easily deformed due to its...
