The Q & U Bolometric Interferometer for Cosmology, QUBIC, is an innovative experiment designed to measure the polarization of the Cosmic Microwave Background and in particular the signature left therein by the inflationary expansion of the Universe. The expected signal is extremely faint, thus extreme sensitivity and systematic control are necessary in order to attempt this measurement. QUBIC addresses these requirements using an innovative approach combining the sensitivity of Transition Edge Sensor cryogenic bolometers, with the deep control of systematics characteristic of interferometers. This makes QUBIC unique with respect to others classical imagers experiments devoted to the CMB polarization. In this contribution we report a description of the QUBIC instrument including recent achievements and the demonstration of the bolometric interferometry performed in lab. QUBIC will be deployed at the observation site in Alto Chorrillos, in Argentina at the end of 2019.
QUBIC: using NbSi TESs with a bolometric interferometer to characterize the polarisation of the CMB
QUBIC（Q \& U Bolometric Interferometer for Cosmology）是一个国际地面实验，专门用于测量宇宙微波背景（CMB）的偏振起伏。它是基于测热干涉测量，一个原始的检测技术相结合的免疫系统的影响与低温非相干探测器的灵敏度的干涉仪。QUBIC将部署在阿根廷萨尔塔省San Antonio de los Cobres附近的Alto Chorrillos山区。QUBIC检测链由2048个冷却至350 mK的NbSi跃迁边缘传感器（TES）组成。电压偏置的TES通过基于1 K超导量子干涉器件（SQUID）和60 K新型SiGe专用集成电路（ASIC）的时域多路复用读取，从而实现前所未有的复用（MUX）因子128。QUBIC实验目前正在实验室中进行表征，在升级到完整仪器之前，减少了探测器的数量。我将介绍这个表征阶段的最后结果，重点是探测器和读出系统。
