论文摘要
在DESY，Alps II实验正在HERA隧道中安装，以寻找像颗粒（阿尔卑斯山）一样的轴突。激光束将被注入一串超导型HERA偶极磁体，以产生阿尔卑斯山。经过浅色壁后，阿尔卑斯山可以在第二串Hera偶极子中重新转入光子。实验的灵敏度将在墙壁之前和后面增加两个模式匹配的光学腔。磁体的曲率限制了光学谐振器的性能，因此，通过拉直弯曲的磁铁轭来增加HERA偶极子内的光学谐振器的光圈。本报告中描述了拉直HERA偶极子的程序。
At DESY the ALPS II experiment is being installed in the HERA tunnel to search for axion like particles (ALPs). A laser beam will be injected into a string of superconducting HERA dipole magnets, to produce ALPs. After passing a light tight wall, the ALPs can reconvert into photons in a second string of HERA dipoles.The sensitivity of the experiment will be increased by two mode-matched optical cavities before and behind the wall. The curvature of the magnets limits the performance of the optical resonators, Therefore the aperture for the optical resonators inside the HERA dipoles was increased by straightening the curved magnet yoke. The procedure of straightening the HERA dipoles is described in this report.
