Two-dimensional scintillation neutron detectors for the extension of SENJU diffractometer

Nakamura, Tatsuya; To, Kentaro; Koizumi, Tomokatsu; Kiyanagi, Ryoji; Ohara, Takashi; Ebine, Masumi; Sakasai, Kaoru

Proceedings of 2020 IEEE Nuclear Science Symposium and Medical Imaging Conference (NSS/MIC 2020), Vol.1, p.483 - 484, 2021/09

Two-dimensional neutron detectors were developed for the extension of SENJU time-of-flight Laue single crystal neutron diffractometer in J-PARC MLF. The detectors are to be installed at the additional detector bank for the SENJU instrument. The detector module is made based on ZnS scintillator and wavelength-shifting fiber technology, where each detector module maintains a neutron-sensitive area of 256$$times$$256 mm with a pixel size of 4$$times$$4 mm. To meet the tight space limitation in the instrument, the detector was designed as compact as possible. The detector has a depth of 170 mm, which is about 40% smaller than that of the original SENJU detector. All four produced detectors exhibited similar detector performances: detection efficiency 50-60% for 2-${AA}$ neutron, $$^{60}$$Co gamma-ray sensitivity 1$$times$$10$$^{-5}$$, count uniformity 3-6%.

Single-crystal neutron diffraction study of the heavy-electron superconductor CeNiGe$$_{3}$$

Ikeda, Yoichi*; Ueta, Daichi*; Yoshizawa, Hideki*; Nakao, Akiko*; Munakata, Koji*; Ohara, Takashi

Single-crystal neutron diffraction study was performed for anomalous antiferromagnetic ordering in a heavy-electron superconductor CeNiGe$$_{3}$$. We observed incommensurate magnetic Bragg reflections characterized with the propagation vector of $$k_{2}$$ = (0; 0:41; 1=2) below the N$'e$el temperature of 5 K, while there is no significant magnetic reflection at the commensurate propagation vector of $$k_{1}$$ = (1; 0; 0) at which another magnetic reflection was observed in the previous neutron diffraction study with a polycrystalline sample. From the single crystal study, we suggest that the magnetic phase of CeNiGe$$_{3}$$ at ambient pressure is characterized only by the incommensurate propagation vector $$k_{2}$$.
