Proof-of-Principle Experiment on a Displacement-Noise-Free Neutron Interferometer for Gravitational Wave Detection
Shoki Iwaguchi, Takuhiro Fujiie, Taro Nambu +13
The displacement-noise-free interferometer (DFI) is designed to eliminate all displacement-induced noise while retaining sensitivity to gravitational wave (GW) signals. Ground-base…

Demonstration of Near-Epithermal Neutron Reflective Optics
Takuhiro Fujiie, Ryota Abe, Masahiro Hino +11
Specular reflection of neutrons on material surfaces has been demonstrated in the energy range of 0.09-0.7 eV. The results suggest that the applicable energy range of reflective ne…

Sagnac-type neutron displacement-noise-free interferometeric gravitational-wave detector
Yuki Kawasaki, Shoki Iwaguchi, Tomohiro Ishikawa +13
The detection of low-frequency gravitational waves on Earth requires the reduction of displacement noise, which dominates the low-frequency band. One method to cancel test mass dis…
