A compact two-electrode field-emission X-ray source for soft X-ray spectroscopy applications [PDF]

Journal of Synchrotron Radiation
Here, a compact two-electrode field-emission X-ray source employing a blade-type tungsten cathode was designed for soft X-ray spectroscopy. The device suppressed filament-derived optical and thermal background that is intrinsic to thermionic tubes, while

X ray spectroscopy on 𝚵− atoms (J-PARC E03, E07 and future) [PDF]

EPJ Web of Conferences, 2022
X-ray spectroscopy of hadronic atoms is a powerful method to study strong interaction between hadrons and nuclei. At J-PARC, we have conducted two experiments, J-PARC E07 and E03, for hadronic atoms with a doubly strange hyperon, Ξ−, aiming at the world ...

Effect of germanium oxide on the structural aspects and bioactivity of bioactive silicate glass

Scientific Reports, 2023
Ternary silicate glass (69SiO2–27CaO–4P2O5) was synthesized with the sol–gel route, and different percentages of germanium oxide GeO2 (6.25, 12.5, and 25%) and polyacrylic acid (PAA) were added.
