Autor: Fujiie, Takuhiro, Abe, Ryota, Hino, Masahiro, Hishida, Mayu, Hosobata, Takuya, Kitaguchi, Masaaki, Nakabe, Rintaro, Oikawa, Kenichi, Okudaira, Takuya, Parker, Joseph D., Sakai, Kenji, Shimizu, Hirohiko M., Tsuchikawa, Yusuke, Yamagata, Yutaka

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 neutron optics can be extended to the near-epithermal region by using ex

Development of a near-infrared wide-field integral field unit by ultra-precision diamond cutting

Publikováno v: Journal of Astronomical Telescopes, Instruments, and Systems, Vol. 10, Issue 1, 015004 (March 2024)

Integral Field Spectroscopy (IFS) is an observational method to obtain spatially resolved spectra over a specific field of view (FoV) in a single exposure. In recent years, near-infrared IFS has gained importance in observing objects with strong dust

Development of Neutron Interferometer using Multilayer Mirrors and Measurements of Neutron-Nuclear Scattering Length with Pulsed Neutron Source

Autor: Fujiie, Takuhiro, Hino, Masahiro, Hosobata, Takuya, Ichikawa, Go, Kitaguchi, Masaaki, Mishima, Kenji, Seki, Yoshichika, Shimizu, Hirohiko M., Yamagata, Yutaka

This study entailed the successful deployment of a novel neutron interferometer that utilizes multilayer mirrors. The apparatus facilitates a precise evaluation of the wavelength dependence of interference fringes utilizing a pulsed neutron source. O

Pendell\'{o}sung Interferometry Probes the Neutron Charge Radius, Lattice Dynamics, and Fifth Forces

Autor: Heacock, Benjamin, Fujiie, Takuhiro, Haun, Robert W., Henins, Albert, Hirota, Katsuya, Hosobata, Takuya, Huber, Michael G., Kitaguchi, Masaaki, Pushin, Dmitry A., Shimizu, Hirohiko, Takeda, Masahiro, Valdillez, Robert, Yamagata, Yutaka, Young, Albert

Structure factors describe how incident radiation is scattered from materials such as silicon and germanium and characterize the physical interaction between the material and scattered particles. We use neutron pendell\"{o}sung interferometry to make
