International Team Measures Niobium-94 Neutron Reactions, Explaining Anomalous Molybdenum-94 Abundance in the Solar System

An international team of physicists has, for the first time, conducted a comprehensive study of the interactions between neutrons and the niobium-94 isotope. The findings have been published in Physical Review Letters. The study suggests that the elevated abundance of molybdenum-94 in the primordial material of the solar system can be explained by a series of neutron-involving nuclear reaction processes inside old stars, without requiring the introduction of previously unknown special formation mechanisms. The research was led by Alberto Mengoni, a researcher at the Italian National Institute for Nuclear Physics. The team conducted experiments using the n_TOF facility at CERN, focusing on tracking the interactions between neutrons and niobium-94 atoms. The n_TOF facility is used to...

South Korea's semiconductor cluster adds about 21 GW of new power demand; government to study whether to build new nuclear units

South Korea's Minister of Climate, Energy and Environment, Kim Sung-hwan, said on the 10th that the new electricity demand from the Yongin—Hoseon semiconductor industry cluster is approximately 21 GW, equivalent to the power supply capacity of about 15 nuclear units based on an estimate of 1.4 GW per unit. The Ministry of Climate, Energy and Environment plans to seek expert and public opinions before announcing the 12th Basic Plan for Electricity Supply and Demand in October, and will decide accordingly whether to push for the construction of new nuclear units. Kim Sung-hwan stated that the electricity demand of the semiconductor industry has increased significantly compared to the past. The South Korean government has decided to raise renewable energy capacity from 78 GW to 100 GW by 2030, but whether the increase in renewable energy alone can meet the new demand still requires further assessment.

CMS records highest-energy lepton pairs to date, testing the possibility of a composite Higgs boson

The CMS experiment recently used the complete proton-proton collision dataset collected during Run 2 of the Large Hadron Collider and the first two years of Run 3, namely 2022 to 2023, to search for clues that the Higgs boson may be composed of smaller constituents. The analysis results show that the experimental data are consistent with Standard Model predictions, with no evidence pointing to new physics yet. Whether the Higgs boson is an elementary particle or a composite particle with deeper structure is a long-standing question in particle physics. To test this possibility, the CMS team adopted two complementary approaches: on one hand, directly searching for new heavy particles that could be produced at the Large Hadron Collider; on the other hand, indirectly probing the effects of new particles with higher masses that are difficult to produce directly through subtle deviations in high-energy electron pair and muon pair production processes.

CMS completes high-pileup collision test, validating particle reconstruction algorithms for High-Luminosity LHC operation

In 2025, the Large Hadron Collider (LHC) conducted a dedicated test over several days to simulate high-intensity collision conditions closer to those expected during future operation of the High-Luminosity Large Hadron Collider (HL-LHC). The Compact Muon Solenoid (CMS) experiment team used this opportunity to test whether existing particle tracking, identification, and reconstruction software, along with a new class of machine learning methods, can adapt to the more complex collision conditions of the HL-LHC era. During LHC operation, each crossing of proton beams produces multiple proton–proton collisions simultaneously, a phenomenon known as pileup. The current Run 3 features approximately 65 simultaneous interactions, while the HL-LHC is expected to reach 140 to 200. To...

Japanese research team demonstrates ion wakefield acceleration for the first time, accelerating protons to a maximum of 60 MeV

Kyushu University, the National Institutes for Quantum Science and Technology (QST), and Osaka University recently announced jointly that the research team used high-intensity laser irradiation on a foam target to experimentally demonstrate the ion wakefield acceleration mechanism for the first time, providing a new experimental foundation for research on next-generation laser-driven ion accelerators. The results were published in *Communications Physics* on August 3, Japan time. According to the report, the research aims to reproduce physical processes similar to high-energy particle acceleration in space within a laboratory setting. Traditional high-energy accelerators typically require long acceleration tubes or large ring-shaped facilities, while the strong electric fields generated by plasma waves are considered promising for advancing accelerator miniaturization. However, compared with electrons, protons and ions...

Consolidating Foundations·Sichuan: Accelerated Localization of Nuclear Medical Equipment Benefits the Public

On August 9, 2026, CCTV's "Morning News" program aired a feature titled "Consolidating Foundations·Sichuan: Accelerated Localization of Nuclear Medical Equipment Benefits the Public," reporting on Jiuyiyuan Company. Founded in February 2017, Sichuan Jiuyiyuan Particle Technology Co., Ltd. is a national high-tech enterprise integrating R&D, production, and services of high-end nuclear medical equipment, committed to providing overall solutions for radiopharmaceuticals. A cyclotron is a device that uses magnetic and electric fields to drive charged particles in a circular motion, repeatedly accelerating them via high-frequency electric fields during their movement. Low- and medium-energy cyclotrons applied in the medical field are devices that produce positron-emitting radionuclides, generating a variety of radionuclides that not only meet clinical PET/CT examination needs but also support the clinical positron drug and new drug development demands of the molecular imaging and precision medicine era. The report noted that core nuclear medicine equipment has long relied on imports, which is a key bottleneck constraining the development of nuclear medicine in China. In 2021, Jiuyiyuan successfully developed the first domestically produced medical cyclotron, breaking foreign technological monopoly. In June this year, the company launched the first domestically produced 30MeV multi-particle medium-to-high-energy cyclotron with fully independent intellectual property rights, with mass production planned for September, achieving internationally advanced product performance.
