论文摘要
QUBIC的Q&U射量干涉仪是一个创新的实验,旨在测量宇宙微波背景的极化,尤其是宇宙的通货膨胀膨胀所留下的签名。预期信号非常微弱,因此必须进行极端灵敏度和系统控制才能尝试进行此测量。 Qubic使用一种创新的方法来解决这些要求,结合了过渡边缘传感器低温测量仪的灵敏度,以及对干涉仪系统特征的深控制控制。这使得Qubic在其他经典成像仪实验方面独特,专门用于CMB极化。在这项贡献中,我们报告了Qubic仪器的描述,包括最近的成就以及在实验室中进行的隆型测量学干涉法的演示。 Qubic将于2019年底部署在阿根廷Alto Chorrillos的观察地点。
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.
