German Team Achieves Ultrafast Shaping of Extreme Ultraviolet Pulses Using High-Density Helium Gas

August 20, 2026, the international team led by researchers from the Max Planck Institute for Nuclear Physics (MPIK) in Heidelberg announced that they have utilized atomic gas as a rapidly switchable time-varying lens to control the beam shape and spectrum of intense high-frequency laser pulses. This achievement is expected to provide a new pathway for the fine control of extreme ultraviolet (XUV) and X-ray pulses, and may serve research directions such as improved spectroscopic methods, control of chemical reactions, and quantum computing. Extreme ultraviolet light can provide important tools for studying atomic-scale processes. With the development of free-electron lasers, researchers have been able to generate ultrashort, high-intensity XUV light pulses, but how to manipulate them like...

Gallium ion FIB-SEM sample preparation has a damage limit; low-energy argon ion beam cleaning is used to improve TEM sample quality

Gallium ion focused ion beam-scanning electron microscopy (Ga⁺ FIB-SEM) has become an important method for site-specific thin lamella sample preparation for transmission electron microscopy/scanning transmission electron microscopy (TEM/STEM), enabling cutting, extraction, and thinning of target regions at the nanometer scale. However, the literature indicates that while gallium ions provide high-precision machining capability, they also cause amorphization, ion implantation, and localized chemical modification on the sample surface, which can subsequently affect high-resolution imaging and energy dispersive spectroscopy analysis results. According to the literature, Ga⁺ FIB-SEM typically enables high-resolution site-specific machining at 30 keV, but high-energy gallium ions form a damage layer on the sample sidewalls. Taking silicon as an example...

Japan nuclear waste, geological disposal, literature survey, Hitachiomiya City

Japan's Ministry of Economy, Trade and Industry (METI) is in the final stages of coordination regarding the site selection process for the final disposal of high-level radioactive waste, with plans to request Hitachiomiya City in Ibaraki Prefecture to conduct a literature survey. The literature survey is the first phase of Japan's screening process for selecting a final disposal site for high-level radioactive waste generated from nuclear power generation. It primarily relies on existing literature and materials to assess whether candidate areas have safety concerns such as volcanoes and active faults. Hitachiomiya City is located in the northwestern part of Ibaraki Prefecture, bordering Tochigi Prefecture, with a population of slightly over 35,000. The city does not face the sea, with the Kuji River and Naka River flowing through its territory. Forests account for approximately 60% of the city's total area, and agriculture and manufacturing are the main industries. In recent years, the city has been promoting tourism and emerging industries leveraging the natural environment, while also facing challenges such as population decline, aging, and fiscal pressure.

German Chancellor Links High Electricity Prices to Hasty Nuclear Phase-Out

German Chancellor Friedrich Merz stated that Germany's current high electricity prices are partly attributable to the hasty closure of nuclear power plants. He believes that Germany exited nuclear energy without adequate alternative solutions and now has to bear higher costs for subsequent energy supply arrangements. In an interview, Merz said that the closure of Germany's nuclear plants was not his responsibility, and "if it were up to me, I would not have done this." He noted that the decision has already been made, and the current government cannot change the established facts nor provide a legal guarantee for grid electricity prices over the next 15 years. Merz also mentioned that the impact of the Iran conflict is one of the factors driving up electricity prices. In terms of electricity...

Zaporizhzhia Nuclear Power Plant Relies on Emergency Diesel Generators to Maintain Operations

The International Atomic Energy Agency (IAEA) recently stated that the Zaporizhzhia Nuclear Power Plant (ZNPP) has been relying on emergency diesel generators to maintain critical safety systems for over a week following the interruption of its external power supply. After inspections by the agency's on-site expert team, it was confirmed that as of the 23rd local time, the plant's diesel reserves could support approximately 10 days of operation, approaching the minimum regulatory requirement. According to the IAEA, the Zaporizhzhia Nuclear Power Plant lost its connection to the only remaining 330 kV Peresopravna-1 external transmission line starting on the 20th. Subsequently, the plant activated multiple emergency diesel generators to power critical equipment, including the six reactors and pumps related to spent fuel cooling and storage. The IAEA...

Domestically Produced Nuclear-Grade Resins Fully Verified and Ready for Use

On August 28, China General Nuclear Power Group (hereinafter referred to as CGN) announced that five nuclear-grade resin products developed under its leadership have all been put into engineering application, with a cumulative total of 12 batches used at nuclear power plants including Daya Bay, Ningde, Yangjiang, Taishan, and Hongyanhe. Among them, the first product has been operating stably for over three years in the steam generator blowdown system (APG system) of nuclear power plants, with key performance indicators comprehensively outperforming imported counterparts of the same category, and the domestic nuclear-grade resin production line. Nuclear-grade resins are known as the "kidneys" of nuclear power water treatment systems, serving as core materials that ensure stable water chemistry indicators of nuclear power units and prevent equipment corrosion. For a long time, these materials have been highly dependent on imports, posing supply security risks such as long delivery cycles, unstable batch quality, and rising prices year by year.

Japanese Nuclear Regulator Inspects Horonobe Geological Disposal Research Facility for High-Level Radioactive Waste

On August 28, Shinya Nagasaki and other members of Japan's Nuclear Regulation Authority (NRA) inspected an underground research facility in Horonobe Town, Japan. The facility, operated by the Japan Atomic Energy Agency (JAEA), conducts technical research on deep geological disposal of high-level radioactive waste. Geological disposal of high-level radioactive waste involves encapsulating the waste and burying it deep underground, achieving long-term isolation through engineered and natural geological barriers. During the inspection, Nagasaki and his delegation examined test facilities used to evaluate the corrosion resistance of iron containers. The tests simulate the environment of containers holding heat-generating radioactive waste after being buried underground...
