Development of an Extensible Unified Control System Using the STARS Framework and Common Commands for Detector Control
Ryutaro Nishimura, Yuki Shibazaki, Daisuke Wakabayashi +5
A zooming optical system comprising two Fresnel zone plates (FZPs) was developed and installed at the AR-NE1A beamline of the Photon Factory, High Energy Accelerator Research Organ…
Recent application studies of an INTPIX4NA SOIPIX detector-based X-ray camera using an SiTCP-XG 10GbE-based high-speed readout system at KEK facilities
Ryutaro Nishimura, Noriyuki Igarashi, Daisuke Wakabayashi +10
The Silicon-On-Insulator PIXel (SOIPIX) detector is a unique monolithic structure imaging device currently being developed by the SOIPIX group, led by the High Energy Accelerator R…
Development of a new phase-retrieval algorithm from a single-shot image for X-ray schlieren microscopy
Ryutaro Nishimura, Yoshio Suzuki, Hiroshi Sugiyama +5
In this paper, a new phase-retrieval algorithm from an X-ray schlieren image is proposed. The schlieren method allows phase-contrast imaging with an objective lens and a knife-edge…
X-ray imaging camera using INTPIX4NA SOIPIX detector with SiTCP-XG 10GbE based high-speed readout system
Ryutaro Nishimura, Noriyuki Igarashi, Daisuke Wakabayashi +4
The silicon-on-insulator pixel (SOIPIX) detector is a unique monolithic-structure imaging device currently being developed by the SOIPIX group led by the High Energy Accelerator Re…
Microscale Hydrogen, Carbon, and Nitrogen Isotopic Diversity of Organic Matter in Asteroid Ryugu
Larry R Nittler, Jens Barosch, Katherine Burgess +57
We report the H, C, and N isotopic compositions of microscale (0.2 to 2m) organic matter in samples of asteroid Ryugu and the Orgueil CI carbonaceous chondrite. Three regolith p…
Presolar stardust in asteroid Ryugu
Jens Barosch, Larry R. Nittler, Jianhua Wang +121
We have conducted a NanoSIMS-based search for presolar material in samples recently returned from C-type asteroid Ryugu as part of JAXA's Hayabusa2 mission. We report the detection…
Development of a versatile micro-focused angle-resolved photoemission spectroscopy system with Kirkpatrick-Baez mirror optics
Miho Kitamura, Seigo Souma, Asuka Honma +11
Angle-resolved photoemission spectroscopy using a micro-focused beam spot (micro-ARPES) is becoming a powerful tool to elucidate key electronic states of exotic quantum materials.…
