AI总结:

PolarKID项目测试新型偏振源测量方法,结合KISS仪器与多种模拟源,采用LEKIDs探测器,旨在识别影响CMB偏振B模探测的仪器系统误差,服务下一代CMB望远镜。

摘要:

PolarKID项目的目标是测试一种用于偏振源测量的新方法,以识别所有可能影响宇宙微波背景(CMB)偏振B模探测的仪器系统误差。该项目采用KISS(KIDs干涉仪光谱巡天)仪器,搭配天空模拟器以及点状黑体(模拟行星)、偶极子(延展源)和偏振片等源。我们使用填充阵列式集总元件动能电感探测器(LEKIDs),因为这类探测器在测光和偏振测量配置下观测均具备多重优势。

英文摘要:

The goal of the PolarKID project is testing a new method for the measurement of polarized sources, in order to identify all the possible instrumental systematic effects that could impact the detection of CMB B-modes of polarization. It employs the KISS (KIDs Interferometer Spectrum Survey) instrument coupled to a sky simulator and to sources such as point-like black bodies (simulating planets), a dipole (extended source) and a polarizer. We use filled-arrays Lumped Element Kinetic Inductance Detectors (LEKIDs) since they have multiple advantages when observing both in a photometry and in a polarimetry configuration
