High-accuracy three-combination quadrupole lens

Abstract

The invention relates to the technical field of mechanical design and manufacture of an accelerator beam transporting line electromagnet system, in particular to a high-accuracy three-combination quadrupole lens. The high-accuracy three-combination quadrupole lens comprises a composite unit peripheral framework; a high-accuracy quadrupole lens is arranged in the composite unit peripheral framework by a connecting rod and a stainless steel block; a magnet coil is arranged inside the high-accuracy quadrupole lens; an electrical connecting plate which is connected with the magnet coil is arranged at the lower part of the high-accuracy quadrupole lens; a linear guide rail seat, a rolling guide rail seat and a moving plate are arranged at the upper part of the composite unit peripheral framework; a linear guide rail is arranged on the liner guide rail seat; and a rolling guide rail is arranged on the rolling guide rail seat. High requirement on physical experiments for the engineering manufacture is realized by adopting a bran-new design thinking and a mechanical structure and selecting a reasonable technology and a manufacture mean. Specific schemes and experiences are provided to research institutions and enterprises for manufacturing the quadrupole lens with high accuracy. The high-accuracy three-combination quadrupole lens can reach the micron level installing precision and thestability required by experiments.

Description

technical field [0001] The invention relates to the mechanical design and manufacture technical field of an accelerator beam transport line electromagnet system, in particular to a high-precision three-combination quadrupole lens. Background technique [0002] The heavy ion microbeam device is a device that reduces the heavy ion beam spot of irradiated materials or biological cells to the micron level, and can accurately locate and count the irradiated ions. It is a powerful tool for conducting research on radiation biology, radiation biomedicine and radiation materials science; it also has unique advantages and application prospects in the application fields of material analysis and microprocessing. At present, most of the micro-beam devices in the world provide low-energy light particle beams, and higher-energy heavy ion micro-beams will make it possible to study high-energy, high-charge single event effects, such as astronauts exposed to single-particle radiation during s...
