New Metamaterial Structures for Studying the Oldest Light in the Universe
Posted by Genevieve Klien in categories: cosmology, mapping, particle physics
The cosmic microwave background, or CMB, is the electromagnetic echo of the Big Bang, radiation that has been traveling through space and time since the very first atoms were born 380000 years after our universe began. Mapping minuscule variations in the CMB tells scientists about how our universe came to be and what it’s made of.
To capture the ancient, cold light from the CMB, researchers use specialized telescopes equipped with ultrasensitive cameras for detecting millimeter-wavelength signals. The next-generation cameras will contain up to 100000 superconducting detectors. Fermilab scientist and University of Chicago Associate Professor Jeff McMahon and his team have developed a new type of metamaterials-based antireflection coating for the silicon lenses used in these cameras.
“There are at least half a dozen projects that would not be possible without these,” McMahon said.

Supercomputer-Powered Machine Learning Supports Fusion Energy Reactor Design
Posted by Shailesh Prasad in categories: nuclear energy, particle physics, robotics/AI, supercomputing
Energy researchers have been reaching for the stars for decades in their attempt to artificially recreate a stable fusion energy reactor. If successful, such a reactor would revolutionize the world’s energy supply overnight, providing low-radioactivity, zero-carbon, high-yield power – but to date, it has proved extraordinarily challenging to stabilize. Now, scientists are leveraging supercomputing power from two national labs to help fine-tune elements of fusion reactor designs for test runs.
In experimental fusion reactors, magnetic, donut-shaped devices called “tokamaks” are used to keep the plasma contained: in a sort of high-stakes game of Operation, if the plasma touches the sides of the reactor, the reaction falters and the reactor itself could be severely damaged. Meanwhile, a divertor funnels excess heat from the vacuum.
In France, scientists are building the world’s largest fusion reactor: a 500-megawatt experiment called ITER that is scheduled to begin trial operation in 2025. The researchers here were interested in estimating ITER’s heat-load width: that is, the area along the divertor that can withstand extraordinarily hot particles repeatedly bombarding it.

Decades-Long Experiment Finds Strange Mix of Antimatter in The Heart of Every Proton
Posted by Shailesh Prasad in category: particle physics
Like the Universe’s tiniest matryoshka dolls, atoms are typically modelled as particles within particles – a nuclei built of protons and neutrons, which in turn contain trios of fundamental particles called quarks.
