KAGRA是日本岐阜县神冈煤矿地下建造的低温干涉型引力波探测器。我们进行了优化的干涉仪的设计，以实现最佳的灵敏度和稳定的操作，与经典噪声的边界条件和各种实际的约束下，如隧道的大小或反射镜的冷却能力。长度和对准传感方案的干涉仪的鲁棒控制的开发。在本文中，我们描述了KAGRA干涉仪的详细设计以及设计选择背后的推理。
KAGRA is a cryogenic interferometric gravitational-wave detector being constructed at the underground site of Kamioka mine in Gifu prefecture, Japan. We performed an optimization of the interferomter design, to achieve the best sensitivity and a stable operation, with boundary conditions of classical noises and under various practical constraints, such as the size of the tunnel or the mirror cooling capacity. Length and alignment sensing schemes for the robust control of the interferometer are developed. In this paper, we describe the detailed design of the KAGRA interferometer as well as the reasoning behind design choices.
