标题： Optical Demonstration of THz, Dual-Polarization Sensitive Microwave Kinetic Inductance Detectors

摘要： 下一代BLAST实验（BLAST-TNG）是一个亚轨道气球载荷，旨在绘制250$\mu$m、350$\mu$m和500$\mu$m波段的极化尘埃辐射。 该仪器利用步进半波片来减少系统误差。 探测器的一般要求是它们为光子噪声限制且具有双极化敏感性。 为了达到这个目标，我们正在开发三个低温传感器的单片阵列，每个波段一个。 每个阵列都是馈电喇叭耦合的，每个空间像素由两个正交放置的极化敏感微波动能电感探测器（MKIDs）组成，这些探测器采用Ti/TiN多层膜制造。 在以前的工作中，我们在250$\mu$m波段单极化器件中展示了光子噪声限制的灵敏度。 在这项工作中，我们展示了在250$\mu$m处双极化敏感MKIDs的首次结果。 显示英文摘要

摘要： The next generation BLAST experiment (BLAST-TNG) is a suborbital balloon payload that seeks to map polarized dust emission in the 250 $\mu$m, 350 $\mu$m and 500 $\mu$m wavebands. The instrument utilizes a stepped half-wave plate to reduce systematics. The general requirement of the detectors is that they are photon-noise-limited and dual-polarization sensitive. To achieve this goal, we are developing three monolithic arrays of cryogenic sensors, one for each waveband. Each array is feedhorn-coupled and each spatial pixel consists of two orthogonally spaced polarization-sensitive microwave kinetic inductance detectors (MKIDs) fabricated from a Ti/TiN multilayer film. In previous work, we demonstrated photon-noise-limited sensitivity in 250 $\mu$m waveband single polarization devices. In this work, we present the first results of dual-polarization sensitive MKIDs at 250 $\mu$m.
