LHAASO

LHAASO "Sees" for the First Time How Black Holes Produce the Highest-Energy Particles in the Universe

How do black holes accelerate particles to the highest energies in the universe? The latest research provides the answer. On July 31, it was learned from the Institute of High Energy Physics of the Chinese Academy of Sciences that the Large High Altitude Air Shower Observatory (LHAASO, "Lasso"), a major national scientific and technological infrastructure, has for the first time clearly observed the process by which a black hole, while devouring material from its companion star, regularly produces the highest-energy particles in the universe like a metronome, and has identified the first PeV gamma-ray variable source. The related research results were published in the *National Science Review*. Cygnus X-3 is a binary system located in the constellation Cygnus, consisting of a black hole and a massive companion star. The gravitational pull there is extremely strong, and the black hole frantically accretes the stellar wind blown off by its companion. LHAASO detected...

Russian researchers detect anomalous signs in bottomonium states using Belle II experiment data

Russian researchers detect anomalous signs in bottomonium states using Belle II experiment data

The Budker Institute of Nuclear Physics of the Siberian Branch of the Russian Academy of Sciences recently announced that Russian researchers have detected anomalous phenomena in the analysis of data from the international Belle II experiment, indicating that the structure of certain excited states of bottomonium may be more complex than predicted by traditional models. Bottomonium is a class of unstable heavy particles composed of a bottom quark and an anti-bottom quark. Yevgeny Kovalenko, a young researcher at the Budker Institute of Nuclear Physics of the Siberian Branch of the Russian Academy of Sciences, stated that analysis of Belle II experiment data suggests that certain excited states of bottomonium may contain lighter quark components. In other words, these particles in specific states may not simply be plain bottom quark–anti-bottom quark combinations.

n situ GIWAXS characterization using synchrotron radiation helps overcome challenges in wide-bandgap perovskites

n situ GIWAXS characterization using synchrotron radiation helps overcome challenges in wide-bandgap perovskites

Wide bandgap perovskites are key light-absorbing materials for preparing high-efficiency perovskite/organic tandem solar cells. To achieve spectral matching with the narrow bandgap organic rear cell, a higher proportion of bromine is usually introduced into the perovskite composition. However, due to the different crystallization rates of iodine and bromine components during film formation, the ph...

U.S. Brookhaven National Laboratory Achieves Milestones in High-Luminosity Large Hadron Collider Upgrade

U.S. Brookhaven National Laboratory Achieves Milestones in High-Luminosity Large Hadron Collider Upgrade

On July 29, the Large Hadron Collider (LHC) at CERN concluded its recent run and entered a four-year shutdown for maintenance. During this shutdown, some LHC components will be dismantled and rebuilt for the High-Luminosity LHC (HiLumi LHC) upgrade project. The U.S. Department of Energy's Brookhaven National Laboratory has recently achieved important production milestones in both accelerator and detector-related work. The LHC helps scientists study the fundamental structure of matter by accelerating and colliding two beams of protons traveling in opposite directions in a nearly 17-mile circular ring. The core goal of the HiLumi LHC upgrade is to significantly increase the number of particle collisions per unit time, i.e., enhance "luminosity," thereby increasing the chance of recording rare interactions.

Northwest Nuclear and Radiation Safety Supervision Station of the Ministry of Ecology and Environment Completes Routine Supervision and Emergency Assessment of Thorium-based Molten Salt Reactor

Recently, the Northwest Nuclear and Radiation Safety Supervision Station of the Ministry of Ecology and Environment (hereinafter referred to as the Northwest Supervision Station) organized a supervision team to conduct routine nuclear and radiation safety supervision and comprehensive emergency drill assessment for the 2 MW Liquid Fuel Thorium-based Molten Salt Experimental Reactor (hereinafter referred to as the Thorium-based Molten Salt Reactor) of the Shanghai Institute of Applied Physics, Chinese Academy of Sciences (hereinafter referred to as Shanghai Institute of Applied Physics). This supervision focused on the operational safety of the Thorium-based Molten Salt Reactor, effluent and environmental monitoring, radiation safety of nuclear technology utilization projects, and comprehensive emergency drills. The supervision team, through document review, on-site verification, and record tracing, primarily examined the effectiveness of the quality assurance program, personnel training and authorization, effluent and environmental monitoring records, emergency system documents, and the rectification records from previous inspections. At the same time, the supervision team observed the comprehensive emergency drill on-site and provided guidance based on actual conditions, conducting a full-process assessment of accident response procedures, cross-departmental coordination, and emergency response measures. In response to the issues and deficiencies identified during the supervision, the supervision team held a special communication meeting with the Shanghai Institute of Applied Physics and proposed rectification requirements.

Korea Atomic Energy Research Institute and SK Hynix to Jointly Use Proton Accelerator and Other Facilities for Semiconductor Radiation Reliability Research

Korea Atomic Energy Research Institute and SK Hynix to Jointly Use Proton Accelerator and Other Facilities for Semiconductor Radiation Reliability Research

The Korea Atomic Energy Research Institute announced on July 29 that its Proton Science Research Group has signed a mutual cooperation agreement with SK Hynix to jointly utilize research facilities such as the proton accelerator to advance research on semiconductor radiation reliability. According to the agreement, the two parties will conduct joint research on proton beams and neutron beams generated by the proton accelerator and the HANARO research reactor, and explore methods to simulate real atmospheric and cosmic radiation environments using high-energy proton beams, gamma-ray beams, and neutron beams for radiation impact assessment of semiconductors and other products. In outer space and high-altitude aircraft flight environments, the shielding effect of the atmosphere and magnetic field against cosmic radiation is relatively weakened. After being exposed to cosmic radiation, semiconductors may experience malfunctions or damage. Therefore, semiconductors used in mobile devices such as automobiles and satellites need to have their radiation resistance verified before being put into use.
