上钢五厂与上海异型钢管厂共同研制的无磁不锈钢异型管是高能加速器的关键材料之一。用作500亿电子伏特质子同步加速器主环的运行管道,保证质子束流在高真空下加速运行。与国外高能加速器用焊接法生产的异型真空盒相比,我国的无缝异型真空盒自有特色。
Wuchang Steel and Shanghai Shaped Steel Pipe Plant jointly developed non-magnetic stainless steel special-shaped tube is one of the key materials for high-energy accelerator. It is used as a running pipe for the main ring of a 50 billion electron volt proton synchrotron to ensure that the proton beam accelerates under high vacuum. Compared with the special-shaped vacuum box produced by the welding method of foreign high-energy accelerators, the seamless special-shaped vacuum box in our country has its own characteristics.
