Design and Thermal Characteristics of a 400 mm Diameter Levitating Rotor in a Superconducting Magnetic Bearing Operating Below at 10 K for a CMB Polarization Experiment

Yuki Sakurai Tomotake Matsumura Teruhito Iida Hiroaki Kanai Nobuhiko Katayama Hiroaki Imada Hiroyuki Ohsaki Yutaka Terao Toshiki Shimomura Hajime Sugai Hirokazu Kataza Ryo Yamamoto Shin Utsunomiya

IEEE TRANSACTIONS ON APPLIED SUPERCONDUCTIVITY 28(4) 2018年6月

We present the design and thermal characteristics of a levitating rotor in a superconducting magnetic bearing (SMB) system that is designed for a polarization modulator of a cosmic microwave background (CMB) polarization experiment. Thermal charac...

GROUND-BASED AND AIRBORNE INSTRUMENTATION FOR ASTRONOMY VII 10702 2018年

With the imminent launch of the JWST, the field of thermal-infrared (TIR) astronomy will enjoy a revolution. It is easy to imagine that all areas of infrared (IR) astronomy will be greatly advanced, but perhaps impossible to conceive of the new vi...

MILLIMETER, SUBMILLIMETER, AND FAR-INFRARED DETECTORS AND INSTRUMENTATION FOR ASTRONOMY IX 10708 2018年

We present our design and development of a polarization modulator unit (PMU) for LiteBIRD space mission. LiteBIRD is a next generation cosmic microwave background (CMB) polarization satellite to measure the primordial B-mode. The science goal of L...

A Circumstellar Disk around HD 169142 in the Mid-Infrared (N-Band)

Yoshiko Kataza Okamoto Hirokazu Kataza M. Honda T. Yamashita T. Fujiyoshi T. Miyata S. Sako H. Fujiwara I. Sakon M. Fukagawa M. Momose T. Onaka

ASTRONOMICAL JOURNAL 154(1) 2017年7月

The Herbig Ae star HD 169142 is one of the objects that show complex structure, such as multiple (innermost, middle, and outer) disks, gaps, and unresolved sources. We made N-band (8-13 mu m) observations of HD 169142 with the Cooled Mid-Infrared ...
