论文摘要
Alps II，任何光粒子搜索，都是通过墙壁实验闪闪发光的第二代光线，该光线可以追捕轴突样颗粒。该实验目前正在从设计和施工阶段过渡到调试阶段，科学预计将于2021年开始。AlpsII计划使用两种不同的感应方案来确认对轴突样粒子的潜在检测或验证其耦合强度的上限到两个光子的上限$ g_ {aγγ} \ leq2 \ times10^{ - 11} \ text {gev}^{ - 1} $。本文讨论了杂尼感应方案（HET），该方案将是第一个用于检测再生光的方案。它介绍了光学布局，长度和对齐感应方案的关键细节，设计功能以最大程度地减少流浪光中的虚假信号，以及特定于HET的几个控制和否决通道，这些信号是委托和操作仪器并校准探测器敏感性所需的。
ALPS II, the Any Light Particle Search, is a second-generation Light Shining through a Wall experiment that hunts for axion-like particles. The experiment is currently transitioning from the design and construction phase to the commissioning phase, with science runs expected to start in 2021. ALPS II plans to use two different sensing schemes to confirm the potential detection of axion-like particles or to verify an upper limit on their coupling strength to two photons of $g_{aγγ}\leq2\times10^{-11}\text{GeV}^{-1}$. This paper discusses a heterodyne sensing scheme (HET) which will be the first scheme deployed to detect the regenerated light. It presents critical details of the optical layout, the length and alignment sensing scheme, design features to minimize spurious signals from stray light, as well as several control and veto channels specific to HET which are needed to commission and operate the instrument and to calibrate the detector sensitivity.
