AI Technical Summary

Technical Problem

Existing gas charge strippers have low beam acceptance and low beam transmission efficiency, making it difficult to ensure stripping efficiency while avoiding damage to the vacuum level of the vacuum pipe.

Method used

A high-acceptance gas charge stripper was designed, which adopts a vacuum differential structure. Both the stripper tube and the gas resistance tube are variable aperture designs. The center aperture of the stripper tube is small and the apertures at both ends are large. The inner wall of the gas resistance tube gradually decreases from the vacuum chamber to the outside. Combined with the gas extraction port, the stripped gas is collected to ensure that the beam and the stripped gas fully collide and restrict the gas from flowing into the vacuum pipe.

Benefits of technology

This improves the beam acceptance and beam transmission efficiency of the gas charge stripper, ensuring stable operation of the electrostatic tandem accelerator while protecting the vacuum level of the vacuum pipe.

Abstract

This application provides a high-acceptance gas charge stripper for a gas target, the main body of which is a vacuum differential structure. The stripping gas enters the stripping tube from the inlet pipe, and the charged particle beam achieves charge stripping through collision reactions as it passes through the stripping tube. Gas resistance tubes are installed at both ends of the stripping tube to restrict the stripping gas from entering the vacuum pipes at both ends of the vacuum chamber. The inner wall of the stripping tube has a variable aperture structure, with the aperture gradually increasing from the center to both ends, thereby achieving efficient charge exchange. The inner wall of the gas resistance tube also has a variable aperture structure, with the aperture gradually decreasing from inside the vacuum chamber to outside, thereby reducing the impact of the stripping gas on the vacuum level in the vacuum pipes on both sides. By setting the variable-diameter gas resistance tubes, the vacuum system can withstand a higher intake volume of stripping gas, allowing the aperture of the stripping tube to be designed to be larger, thus improving the beam acceptance of the gas charge stripper, increasing beam transmission efficiency, and ensuring the efficient and stable operation of the electrostatic tandem accelerator.
