在HL-LHC项目的框架内，用于升级LHC的MCBXFB嵌套轨道校正器的第二个原型已在CIEMAT制造，并在CERN组装。本文介绍了相对于第一个原型引入的变化，以测试系列磁铁的一些设计改进。对线圈的预紧力进行了研究，旨在提高组合操作中的性能。在欧洲核子研究中心对第二个原型进行了功率测试。当单独供电时，两个偶极子都达到了极限电流而没有任何失超。然而，联合操作的结果并没有改善第一个原型的结果。进一步的分析和研究正在进行中。
The second prototype of the MCBXFB nested orbit corrector for the upgrade of the LHC has been manufactured at CIEMAT and assembled at CERN, in the framework of the HL-LHC project. This paper describes the changes introduced with respect to the first prototype in order to test some design improvements intended for the series magnets. The preload of the coils has been carefully studied, aiming to improve the performance in combined operation. A power test campaign has been carried out for this second prototype at CERN. Both dipoles reached ultimate current without any quench when individually powered. However, the results in combined operation did not improve those of the first prototype. Further analysis and studies are ongoing.
