MCBXF磁体是嵌套的轨道校正器，在高亮度（HL）大型强子对撞机（LHC）项目的框架内，用于大型强子对撞机（LHC）的升级。有两个不同物理长度的版本，1.5和2.5米，它们共享相同的横截面以降低制造成本。这些磁体具有150 mm的大孔径，并且由于高辐射剂量，需要机械夹紧以保持两个偶极子之间的大扭矩。CIEMAT能源、环境和技术研究中心正在与CERN合作开发MCBXFB短原型。本文介绍了磁铁的工程设计，这是基于以前的磁性和力学计算。详细分析了线圈端部的轴向预应力。由于线圈的匝数多、孔径大，一些创新技术已经被开发用于线圈制造。
MCBXF magnets are nested orbit correctors, needed for the upgrade of the large hadron collider (LHC), in the framework of the high luminosity (HL) LHC project. There are two versions with different physical lengths, 1.5 and 2.5 m, which share the same cross section to decrease fabrication costs. These magnets have a large aperture of 150 mm and due to the high radiation dose, a mechanical clamping is necessary to hold the large torque between both dipoles. Centro de Investigaciones Energéticas, Medioambientales y Tecnológicas CIEMAT is developing the short MCBXFB prototype in collaboration with CERN. This paper describes the engineering design of the magnet, which is based on previous magnetic and mechanical calculations. The axial pre-stress on the coil ends is analyzed in detail. Some innovative techniques have been developed for the coil fabrication because of the high number of turns and large aperture.
