B-BOP，SPICA成像旋光仪
B-BOP, the SPICA Imaging Polarimeter
摘要：
我们介绍了未来欧空局-日本宇宙航空研究开发机构SPICA远红外空间观测站上的偏振照相机B-BOP仪器。B-BOP将允许在各种天体物理环境中研究磁场，这要归功于其前所未有的测量亚毫米光线偏振的能力。B-BOP产生的地图将不仅包含总功率的信息，而且还包含偏振度和偏振角的信息，同时在三个光谱带（70，200和350微米）中。B-BOP探测器是超灵敏的硅测辐射热计，对偏振非常敏感。它们的NEP接近10 E-18 W/sqrt（Hz）。我们将介绍仪器的光学和热架构，我们将详细介绍测辐射热计的设计，我们将根据初步的实验室工作展示仪器的预期性能。
英文摘要：
We present the B-BOP instrument, a polarimetric camera on board the future ESA-JAXA SPICA far-infrared space observatory. B-BOP will allow the study of the magnetic field in various astrophysical environments thanks to its unprecedented ability to measure the linear polarization of the submillimeter light. The maps produced by B-BOP will contain not only information on total power, but also on the degree and the angle of polarization, simultaneously in three spectral bands (70, 200 and 350 microns). The B-BOP detectors are ultra-sensitive silicon bolometers that are intrinsically sensitive to polarization. Their NEP is close to 10E-18 W/sqrt(Hz). We will present the optical and thermal architectures of the instrument, we will detail the bolometer design and we will show the expected performances of the instrument based on preliminary lab work.
