Cornell is leading a $77 million effort, beginning April 1, to upgrade the Compact Muon Solenoid (CMS) experiment at the Large Hadron Collider (LHC) at the European Organization for Nuclear Research (CERN).
Scientists studying high-Tc superconductors at the U.S. Department of Energy's Brookhaven National Laboratory have definitive evidence for the existence of a state of matter known as a pair density wave--first predicted by theorists some 50 years ago. Their results show that this phase coexists with superconductivity in a well-known bismuth-based copper-oxide superconductor.
Peering into the darkness to see what we could not previously see, the Hubble Space Telescope has been delighting scientists and the general public with revealing details and images of galaxies and celestial phenomena. The American Institute of Physics recognizes and celebrates the momentous occasion of the 30th anniversary of its launch and Physics Today is highlighting the anniversary in its April issue with a look back at the history of the telescope and analysis of Hubble's discoveries over the past 30 years.
An international team of scientists has published a new study proposing an optimization methodology for designing climate-resilient energy systems and to help ensure that communities will be able to meet future energy needs given weather and climate variability. Their findings were recently published in Nature Energy.
Mapping the electrical conductivity of the heart would be a valuable tool in diagnosis and disease management, but doing so would require invasive procedures, which aren't capable of directly mapping dielectric properties. Significant advances have recently been made that leverage atomic magnetometers to provide a direct picture of electric conductivity of biological tissues, and in Applied Physics Letters, new work in quantum sensors points to ways such technology could be used to examine the heart.
Using the same technology that allows high-frequency signals to travel on regular phone lines, researchers tested sending extremely high-frequency, 200 GHz signals through a pair of copper wires. The result is a link that can move data at rates of terabits per second, significantly faster than currently available channels. In Applied Physics Letters, the scientists discuss their work using experimental measurements and mathematical modeling to characterize the input and output signals in a waveguide.
New measurements confirm, to the highest energies yet explored, that the laws of physics hold no matter where you are or how fast you're moving.
Nuclear physicists from Argonne National Laboratory led an international physics experiment conducted at CERN that utilizes novel techniques developed at Argonne to study the nature and origin of heavy elements in the universe.
PPPL researchers find that jumbled magnetic fields in the core of fusion plasmas can cause the entire plasma discharge to suddenly collapse.
The Sun is a spinning ball of plasma that generates its own magnetic field. As the Sun spews out plasma, it generates solar wind that pulls the Sun's magnetic field along with it, twisting the magnetic field into what is called a Parker spiral. A recent experiment recreated this interaction at a small scale in the laboratory.
Missing March Madness? Let Fermilab fill a small part of the void created in these times of social distancing and shelter-in-place. Participate in Fermilab's sendup of the NCAA tournament: March Magnets. Learn about eight different types of magnets used in particle physics, each with an example from a project or experiment in which Fermilab is a player. Then head over to the Fermilab Twitter feed on March 30 to participate in our March Magnets playoffs.
In this Q&A Satya Gontcho A Gontcho, a lead observer for the Dark Energy Spectroscopic Instrument (DESI), shares her experiences at the DESI site near Tucson, Arizona, including evening observing stints to run through detailed checklists and probe how the instrument's components are working.
In collaboration with Marshall Space Flight Center (MSFC), the Center for Space Plasma and Aeronomic Research (CSPAR) at The University of Alabama in Huntsville (UAH) has a significant role in LEAP - the LargE Area burst Polarimeter - a mission that is one of four proposals approved by NASA for further review.
Scientists are working on ways to build atomic structures to specifications and are studying these methods on a larger scale using 'big atoms.' These 'big atoms' are micro-particles of silica mixed into liquid crystals. Silica particles, when mixed into liquid crystals, can act a lot like individual atoms. The geometry of the particles determines how they interact with each other the same way the electrons around an atom determine how it interacts with other atoms. Scientists can observe interactions in these 'big atoms' with optical microscopes, removing the need for atomic-scale imaging.
The ITER fusion reactor will use rippled magnetic fields to prevent bursts of heat and particles that can damage the walls of the reactor. Physicists have now compared computer simulations of plasma with experimental measurements to understand how controlled magnetic ripples outside the plasma can suppress these bursts.
In a machine learning challenge dubbed the 2020 Large Hadron Collider Olympics, a team of cosmologists from Berkeley Lab developed a code that best identified a mock signal hidden in simulated particle-collision data.
Tsuyoshi Tajima is a research and development engineer and a team leader in the Accelerator Operations and Technology Division at the U.S. Department of Energy Los Alamos National Laboratory.
A summary of key points of the fusion and plasma science community's year-long Community Planning Process that proposes accelerating development of these strategic fields.
Accelerator magnets -- how do they work? Depending on the number of poles a magnet has, it bends, shapes or shores up the stability of particle beams as they shoot at velocities close to the speed of light. Experts design magnets so they can wield the beam in just the right way to yield the physics they're after. Here's your primer on particle accelerator magnets.
Fermilab, Brookhaven National Laboratory and Lawrence Berkeley National Laboratory have achieved a milestone in magnet technology. Earlier this year, their new magnet reached the highest field strength ever recorded for an accelerator focusing magnet. It will also be the first niobium-tin quadrupole magnet to operate in a particle accelerator -- in this case, the future High-Luminosity Large Hadron Collider at CERN.
