Estimation of heat dissipation on a levitating rotor over superconducting magnet bearing

T. Iida Y. Sakurai T. Matsumura H. Sugai H. Imada H. Kataza H. Ohsaki N. Katayama Y. Terao

ADVANCES IN CRYOGENIC ENGINEERING 755 2020年

We report the estimation of the heat dissipation on a levitating rotor over superconducting magnetic bearing operating below 10 K. The continuously rotating mechanism is one of key devices to support the rotation of a sapphire half wave plate (HWP...

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

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...
