Vibration characteristics of a continuously rotating superconducting magnetic bearing and potential influence to TES and SQUID
Shinya Sugiyama, Tommaso Ghigna, Yurika Hoshino +9
We measured the vibration of a prototype superconducting magnetic bearing (SMB) operating at liquid nitrogen temperature. This prototype system was designed as a breadboard model f…
Testbed preparation of a small prototype polarization modulator for LiteBIRD low-frequency telescope
Thuong D. Hoang, Tomotake Matsumura, Ryota Takaku +9
LiteBIRD is the Cosmic Microwave Background (CMB) radiation polarization satellite mission led by ISAS/JAXA. The main scientific goal is to search for primordial gravitational wave…
Modelling TES non-linearity induced by a rotating HWP in a CMB polarimeter
Tommaso Ghigna, Tomotake Matsumura, Yuki Sakurai +5
Most upcoming CMB experiments are planning to deploy between a few thousand and a few hundred thousand TES bolometers in order to drastically increase sensitivity and unveil the B-…
Testing magnetic interference between TES detectors and the telescope environment for future CMB satellite missions
Tommaso Ghigna, Thuong Duc Hoang, Takashi Hasebe +11
The two most common components of several upcoming CMB experiments are large arrays of superconductive TES (Transition-Edge Sensor) detectors and polarization modulator units, e.g.…
Performance of the polarization leakage correction in the PILOT data
