NASA's Chandra Telescope Discovers 84 Mysterious Supersoft X-ray Sources

NASA's Chandra X-ray Observatory recently announced that researchers using the observatory's publicly available observation data discovered 84 mysterious celestial objects known as supersoft X-ray sources in 6 galaxies. The related research was published in Nature Astronomy. Image credit: X-ray: NASA. These objects emit X-rays with unusually low energy and may be accompanied by strong high-energy ultraviolet radiation. The research team stated that the behavior of these objects is clearly different from previously observed known celestial bodies and may provide new clues for explaining the origin of Type Ia supernovae and the electron-stripping mechanism in the intergalactic medium. The 6 galaxies covered by this search include two spiral...

German BESSY II 3D Magnetic Field Experiments Reveal Mechanism of Weak Magnetic Field Control over Magnetic Textures

A team at the Helmholtz-Zentrum Berlin (HZB) in Germany has made progress in controlling magnetic textures in the magnetic material (Fe0.63Ni0.3Pd0.07)3P (abbreviated as FNPP) through 3D magnetic field experiments conducted at the BESSY II synchrotron facility. The research shows that a very small external in-plane magnetic field is sufficient to alter the magnetic stripe structure in this material, providing new experimental evidence for the development of functional magnetic materials for spintronics. FNPP is a magnetic material that exhibits complex magnetic structures at room temperature, making it a focus of spintronics research. Spintronics is considered promising for lower-energy data processing and novel data storage applications. However, to achieve practical applications, the key lies in...

Japanese Team Achieves Femtosecond Soft X-ray Hyperspectral Microscopy, Simultaneously Acquiring Spatial and Energy Information with Single Pulse

On August 21, the Japan Science and Technology Agency, RIKEN, and the University of Tokyo announced that a research team comprising Assistant Professor Yoko Takeo and Associate Professor Takashi Kimura from the Institute for Solid State Physics at the University of Tokyo, Assistant Professor Satoru Egawa from the Research Center for Advanced Science and Technology at the University of Tokyo, and Team Leader Makina Yabashi from the RIKEN SPring-8 Center, among others, successfully developed and implemented a femtosecond soft X-ray hyperspectral microscope. The findings were published on August 20 in the U.S. scientific journal *Optica*. This technology utilizes a single soft X-ray pulse from an X-ray free-electron laser (XFEL) to simultaneously acquire soft X-ray spectra transmitted through different positions of a sample, enabling...

Japan's PF Launches Quantum Multi-Beam Experiments, Achieving Simultaneous Hard and Soft X-ray Measurements

The Photon Factory, a synchrotron radiation facility at the Institute of Materials Structure Science, High Energy Accelerator Research Organization (KEK) in Japan, has recently launched collaborative experiments on the development and research multi-purpose beamlines BL-11A and BL-11B, achieving simultaneous irradiation of the same sample with hard and soft X-rays at the same position. The research results will be published in the international academic journal *Review of Scientific Instruments*. The Photon Factory uses electrons moving at near-light speed to generate high-brightness X-rays, known as synchrotron radiation, for studying material structures and properties. Among these, hard X-rays are better suited for observing the internal structure of materials, while soft X-rays are ideal for analyzing material surfaces and electronic states. Previously, at synchrotron radiation facilities, the two types of X-rays typically had to...

Tohoku University and Rigaku Establish Joint Research Institute for X-ray Metrology

Tohoku University and Rigaku Corporation, a subsidiary of Rigaku Holdings Group, recently announced that they established the "Rigaku-Tohoku University X-ray Metrology Co-Creation Research Institute Beyond The Limits" on August 1, 2026, and commenced joint research. The institute will operate for a period of three years, until July 31, 2029, with the possibility of extension based on research outcomes. According to the announcement, the new institute will focus on upgrading X-ray metrology technologies, establishing new measurement methods, and nurturing the next generation of researchers. As semiconductor devices continue to shrink in size while becoming increasingly multi-layered and multi-material in composition, manufacturing processes are growing more complex, driving rising demand for high-precision, non-destructive evaluation of materials and structures. Existing measurement methods face limitations in evaluating fine structures and precisely analyzing depth-direction structures, making the development of new approaches such as soft X-ray techniques an important direction.

KEK in Japan Completes World's First "Quantum Multi-Beam Utilization" Synchrotron Radiation Beamlines

On August 6, the High Energy Accelerator Research Organization (KEK) announced that the BL-11A and BL-11B beamlines at its Photon Factory (PF) synchrotron radiation experimental facility have been completed as the world's first quantum multi-beam utilization beamlines, enabling the simultaneous use of hard X-ray and soft X-ray beams. According to reports, BL-11A and BL-11B were constructed in collaboration with the Synchrotron Radiation Academic Infrastructure Network. This network consists of synchrotron radiation facilities operated by university joint-use organizations and joint-use/joint-research centers, positioned as scientific research and educational infrastructure. The main feature of the new beamlines is the ability to simultaneously use hard X-ray and soft X-ray under the same experimental conditions, completing observations that previously required separate measurements...
