India's Private Fusion Tokamak PRAGYA Achieves Plasma Operation

Bengaluru-based deep-tech energy startup Pranos Fusion has produced plasma in its experimental device PRAGYA. The company states that PRAGYA is India's first compact tokamak developed by a private enterprise, marking a transition in India's private fusion research and development from the design and manufacturing phase to experimental operation. PRAGYA adopts a compact, low-aspect-ratio tokamak design, primarily used to generate, confine, and control plasma. Tokamaks use strong magnetic fields to confine high-temperature plasma within a toroidal vacuum vessel, creating conditions for future fusion of light atomic nuclei. The fundamental process of fusion reactions is the same mechanism by which the Sun releases energy, but engineering implementation still faces multiple challenges in plasma confinement, magnets, materials, and control systems.

Iran Says Its Atomic Energy Organization's Medical Products Serve Over 1.5 Million Patients Annually

Mohammad Eslami, head of the Atomic Energy Organization of Iran, recently stated that more than 1.5 million patients in Iran use diagnostic and therapeutic products developed by the organization each year, and related medical products have also been exported to multiple countries. Eslami made these remarks at a ceremony held by Iran's nuclear industry to celebrate Physicians' Day. He said that promoting the application of advanced treatment methods is one of the key directions of Iran's scientific and technological development. The progress made by Iranian researchers in cold plasma technology has opened up a "brand-new and promising path" for medical applications. He stated that plasma technology has not only achieved notable results in the research field but has also played a role in healthcare settings.

CERN Large Hadron Collider Data Challenge Models of Oxygen and Neon Nucleus Structure

Physicists at the European Organization for Nuclear Research (CERN), analyzing a new batch of collision data from the CMS detector at the Large Hadron Collider, have found that oxygen and neon nuclei do not behave entirely as predicted by existing models in high-energy collisions. This result indicates that the scientific community's understanding of the shapes and internal structures of certain light nuclei still requires further refinement. In high-energy nuclear collisions, a quark-gluon plasma is briefly formed in the collision region. This state of matter decays rapidly, but the collective flow characteristics of its particles can be used to infer the collision geometry and indirectly provide information about nuclear structure. Researchers believe that symmetric collisions of light ions help better control the initial collision conditions, making them suitable for studying collective responses in small systems.

Berkeley Lab Leads Development of Portable Active-Source Muon Imager

The U.S. Department of Energy's Lawrence Berkeley National Laboratory and Ideon Technologies have received funding from the DOE's Advanced Research Projects Agency-Energy (ARPA-E) to jointly develop a field-deployable active-source muon imaging technology through the Reliable Ore Characterization Using Cornerstone Sensing Technologies (ROCKS) program. The three-year project aims to enhance the detection and characterization of underground critical mineral resources. Image credit: Lawrence Berkeley National Laboratory. Muons are subatomic particles with strong penetrating capability. Previously, Ideon Technologies has used passive muons produced by cosmic rays in the atmosphere for ore body imaging in the mining sector, mapping mineral deposits and analyzing subsurface structures. However, passive muons primarily arrive from above, limiting detection angles; additionally, the natural flux is low—approximately one per square centimeter per minute—and imaging often requires days, weeks, or even months.

Indian research team uses supercomputer to track microscopic mechanisms of turbulence in dusty plasmas

Researchers at the Indian Institute of Technology Jammu (IIT Jammu), in collaboration with the Indian Institute of Technology Kanpur (IIT Kanpur), used supercomputer simulations to study the origin of chaos in dusty plasmas. By tracking the motion of millions of individual particles, the study revealed how turbulent energy is transferred from large-scale vortices to microscopic thermal motion of particles, providing a new computational perspective for nuclear fusion plasma research and astrophysical process analysis. Plasma is often referred to as the fourth state of matter. Unlike solids, liquids, and gases, atoms in plasma are ionized, forming a system composed of positively charged ions and negatively charged electrons. When tiny solid dust particles enter the plasma, these particles absorb electrons and become negatively charged, subsequently undergoing complex interactions with surrounding particles to form dusty plasma.

German research team achieves ultra-compact plasma photocathode injection

A research team from institutions including the Helmholtz-Zentrum Dresden-Rossendorf in Germany has demonstrated an ultra-compact plasma photocathode injection scheme integrated into a hybrid plasma wakefield accelerator on the DRACO laser facility. The study utilized a 150 TW-class laser system to drive a laser wakefield accelerator (LWFA), generating high-peak-current electron beams, which in turn drove a subsequent particle beam wakefield accelerator (PWFA), completing the generation and acceleration of witness electron beams within millimeter-scale plasma structures. Plasma wakefield accelerators can produce accelerating fields far exceeding those of conventional radiofrequency linear accelerators, but how to obtain high-quality, high-brightness electron beams in compact devices...
