Breakthrough Enables Quench Detection in High-Field Magnets for Fusion Reactors

Magnetic field (Hall) probe matrix allows current distributions to be recreated and demountable joints allow current redistribution between CORC cables at each turn. Demountable joints shown here are conceptual. Joint resistances must be on the order of nano-ohms. Credit: Berkeley Lab Researchers at Berkeley Lab's Accelerator Technology & Applied Physics (ATAP) Division have developed a method for detecting and predicting the local loss of superconductivity in large-scale magnets that are capable of generating high magnetic fields. These high-field magnets are a core enabling technology for many areas of scientific research, medicine and energy, where they are used in a range of applications, including in particle accelerators and colliders for high energy [JS1] and nuclear physics, diagnostic and therapeutic medical devices and energy generation, transmission and storage technologies.

Superconductivity Breakthrough: First Direct Visualization of a Zero-Field Pair Density Wave

Image: In this illustration of the superconducting material Eu-1144, the blue and magenta wave shown above the crystal lattice represents how the energy level of the electron pairs (yellow spheres) spatially modulates as these electrons move through the crystal. Credit: Brookhaven National LaboratoryIn the field of superconductivity—the phenomenon in which electrons can flow through a material with essentially zero resistance—the “holy grail” of discovery is a superconductor that can perform under everyday temperatures and pressures. Such a material could revolutionize modern life. But currently, even the “high-temperature” (high-Tc) superconductors that have been discovered must be kept very cold to function—too cold for most applications.

New Superconductor Could Lead to Quantum Computing Breakthrough

Image: A new type of superconductor may just be what physicists have been searching for over the past 40 years. Credit: TheDigitalArtist on PixabaySuperconductivity is the property of zero electrical resistance at ultralow temperatures and was discovered in 1911 by the Dutch physicist Kamerling-Ohnes. It plays a crucial role in many industries and technologies, ranging from quantum computing to energy. “Superconductors are amazing materials which have many strange and unusual properties,” explained Joe Carroll, a Ph.D. researcher at Macroscopic Quantum Matter Group laboratory in University College Cork. “Most famously they allow electricity to flow with zero resistance. That is, if you pass a current through them, they don’t start to heat up; in fact, they don’t dissipate any energy despite carrying a huge current.

Analyzing Transcritical CO2 Compression and Pumping Pathways

 Figure 1: Phase diagram of carbon dioxide above and in the vicinity of the critical point showing the dense fluid, liquid-gas-like supercritical and the transitional (Widom) region. Figure 2: Sensitivity of isobaric heat capacity, cp is examined for 0.5 bar change of pressure at a constant temperature of 35 °C across a range of pressures above the critical point of pure CO2 [3]. Figure 3: Three possible transcritical CO2 compression pathways from 1 bara to 150 bara.[3] Credit: Matt Taher, P.E.Supercritical carbon dioxide exhibits anomalous behavior in the vicinity above the critical point. The Irish physical chemist Thomas Andrews (1863) was the first who studied the supercritical behavior of carbon dioxide. He explained his observations of the fluid state above the critical point as follows: “…the surface of demarcation between the liquid and gas became fainter, lost its curvature, and at last disappeared, the tube being then filled with a fluid which, from its optical and other properties, appeared to be perfectly homogeneous [T. Andrews, Jan. 1870]”.

Credit: Andre at Launcher Space“You’re Going to The Moon” should now be quoted as “You’re Going to Mars.” From the 1990s downturn in the aerospace industry to today’s exponential growth, the demand for precision flow control and flow measurement has continued to follow the same growth trajectory. The focus of Alloy Valves and Control (AVCO) has been on the need to fulfill the requirements of research and development for rocket engine design, test stands, rocket propellant and life support systems for space travel in both unmanned and manned space vehicles.

CCAT Observatory Approaches First Light

Rendering of the Fred Young Submillimeter Telescope. Credit: CPI Vertex Antennentechnik GmbHFor the past six years, CCAT Observatory Inc., a nonprofit research organization formed by more than a dozen academic institutions led by Cornell University, has been developing a new telescope, the Fred Young Submillimeter Telescope (FYST, pronounced “feast”) and its supporting infrastructure to observe at submillimeter wavelengths. The infrastructure is currently under construction at an altitude of 5,600 m near the summit of Cerro Chajnantor in the Atacama Desert of northern Chile, one of the driest places on Earth. Since water vapor absorbs the wavelengths of interest, the site is arguably the best ground-based location for submillimeter observations due to its thin, ultradry atmosphere. Once complete, it will be the second highest observatory in the world.

Goddard Goings: Insight Into Its Past, Present and Future

The slow cooldown of JWST’s MIRI was intentional because it enabled efficient scheduling of the deployment tasks and ensured the cleanliness of the optics by preventing water and molecular contamination transport. Credit: NASA GSFCJames Webb Space Telescope-“I’m Back in the Saddle Again!” – It’s likely anyone reading this article has heard about the James Webb Space Telescope (JWST). The telescope launched on December 25, 2021 (EST) with much fanfare. Over the next month, it traveled to its observation location at the L2 Lagrange point in the earth-sun gravitational system. It has been sitting comfortably at this saddle point for well over a year. Cooling of the instrument didn’t wait until reaching this point. Oh no, this began shortly after the launch from the spaceport in French Guiana because the majority of the telescope was cooled passively via thermal radiation to outer space.
