论文摘要
我们介绍了为Qubic技术演示者开发的喇叭开关系统的设计,制造和性能(宇宙学的$ Q $ \&$ u $ bolometric bolometric bolometric bolometric bolometric bolometric bolometric bolometric bolometric)。该系统由64个背对背双波段(150 \,GHz和220 \,GHz)瓦楞纸式饲料霍恩斯构成,并用机械开关散布在仪器自校准期间,用于选择所需的基线。我们在铝制血小板中制造了喇叭,并用光化学蚀刻并用螺钉机械拧紧。开关是基于打开和关闭背对背角之间的波为指南的钢叶片,并通过微型电磁体操作。我们还根据400个喇叭开关组件的阵列显示了Qubic Full仪器的FeedHorn-Switch系统的当前开发状态。
We present the design, manufacturing and performance of the horn-switch system developed for the technological demonstrator of QUBIC (the $Q$\&$U$ Bolometric Interferometer for Cosmology). This system is constituted of 64 back-to-back dual-band (150\,GHz and 220\,GHz) corrugated feed-horns interspersed with mechanical switches used to select desired baselines during the instrument self-calibration. We manufactured the horns in aluminum platelets milled by photo-chemical etching and mechanically tightened with screws. The switches are based on steel blades that open and close the wave-guide between the back-to-back horns and are operated by miniaturized electromagnets. We also show the current development status of the feedhorn-switch system for the QUBIC full instrument, based on an array of 400 horn-switch assemblies.
