论文摘要
MQXFA四极磁体将安装在高光度LHC中，以形成Q1和Q3内三重三重元素的相互作用点1（ATLAS）和5（CMS）的内部三重元件。一对MQXFA单元组装在不锈钢氦气容器中，包括末端圆顶，以使Q1冷质量或Q3冷质量。 CERN提供低温恒温器组件，并负责HL LHC中的集成和安装。 MQXFA四极杆具有150 mm的光圈，4.2 m的磁长，标称梯度为132.2 t/m，线圈峰场为11.3 t。它们使用NB_3SN导体和由bladders and Keys预装的分段铝贝壳制成的支撑结构。该报告介绍了MQXFA四极磁铁的最终设计。 *高能物理办公室美国能源部的支持
The MQXFA Quadrupole magnets will be installed in High Luminosity LHC to form the Q1 and Q3 inner triplet optical elements in front of the interaction points 1 (ATLAS) and 5 (CMS). A pair of MQXFA units is assembled in a stainless steel helium vessel, including the end domes, to make the Q1 Cold Mass or the Q3 Cold Mass. The US HL LHC Accelerator Upgrade Project* is responsible for the design, manufacturing and test of the Q1/Q3 Cold Masses and the complete MQXFA magnets. CERN provides the cryostat components and is responsible for integration and installation in HL LHC. The MQXFA quadrupoles have 150 mm aperture, 4.2 m magnetic length, nominal gradient of 132.2 T/m, and coil peak field of 11.3 T. They use Nb_3Sn conductor and a support structure made of segmented aluminum shells pre-loaded by using bladders and keys. This report presents the final design of the MQXFA quadrupole magnets. *Supported by the U.S. Department of Energy, Office of Science, Office of High Energy Physics
