Credit: Institute of PhysicsRecently, the Kagome superconductors AV3Sb5 (A = K, Rb and Cs) have attracted enormous attention due to their novel phenomena and rich physics. They exhibit unconventional charge density wave (CDW), giant anomalous Hall effect, and superconductivity. The CDW state is intimately related to the anomalous Hall effect and competes with superconductivity under pressure. Investigating the electronic structure of the CDW state is essential to understand its nature and the related physical properties.

#BlackInQuantum

Illustration by Sandbox Studio, Chicago with Ana KovaBlack scientists have played important roles in the history of quantum physics. In this growing area of specialization, there’s an opportunity to continue that legacy. The sixth person to earn a doctoral degree in physics from an American institution was African American scientist Edward Alexander Bouchet; it was 1876, just 11 years after the US had adopted a constitutional amendment that outlawed slavery. Never again have African Americans made up such a large percentage of US physicists. In fact, it would take another 42 years before a second African American man earned a physics PhD in the United States.

Dark Energy Spectroscopic Instrument (DESI) Creates Largest 3D Map of the Cosmos

The Dark Energy Spectroscopic Instrument (DESI) has capped off the first seven months of its survey run by smashing through all previous records for three-dimensional galaxy surveys, creating the largest and most detailed map of the universe ever. Yet it’s only about 10% of the way through its five-year mission. Once completed, that phenomenally detailed 3D map will yield a better understanding of dark energy, and thereby give physicists and astronomers a better understanding of the past – and future – of the universe. Meanwhile, the impressive technical performance and literally cosmic achievements of the survey thus far are helping scientists reveal the secrets of the most powerful sources of light in the universe. DESI is an international science collaboration managed by the Department of Energy’s (DOE) Lawrence Berkeley National Laboratory (Berkeley Lab) with primary funding for construction and operations from DOE’s Office of Science.

Valcor Releases New White Paper on Cryogenic Launch Vehicle Valves

Launch vehicles, particularly the upper stages, often use cryogenic rocket propellants such as liquid oxygen, liquid hydrogen and liquid methane because of their high specific impulse and high storage density. The pressurization, control and distribution of these propellants requires sophisticated valving that can operate and seal at these extreme temperatures.

Particle Accelerator Magnet Sets Record Using High Temperature Superconductor

Henryk Piekarz of Fermilab’s Accelerator Division controls the flow of cryogens in the high-temperature superconductor magnet prototype. Image: Ryan Postel, FermilabCost- and energy-efficient rapid cycling magnets for particle accelerators are critical for particle physics research. Their performance determines how frequently a circular particle accelerator can receive a bunch of particles, propel them to higher energy, send them to an experiment or target station, and then repeat all over again. A small team of physicists, engineers and technicians at the US Department of Energy’s Fermi National Accelerator Laboratory (Fermilab, CSA CSM), led by Henryk Piekarz, demonstrated the world’s fastest magnetic ramping rates for particle accelerator magnets. Noteworthy, they achieved this record by using magnets made with energy-efficient, high temperature superconducting material.

The Second Quantum Revolution

For physicists trying to harness the power of electricity, no tool was more important than the vacuum tube. This lightbulb-like device controlled the flow of electricity and could amplify signals. In the early 20th century, vacuum tubes were used in radios, televisions and long-distance telephone networks. But vacuum tubes had significant drawbacks: They generated heat; they were bulky; and they had a propensity to burn out. Physicists at Bell Labs, a spin-off of AT&T, were interested in finding a replacement.

NSF Grant Funds New 40T Superconducting Magnet Design

A new $15.8 million grant from the National Science Foundation (NSF) will produce a detailed design for the world’s most powerful superconducting magnet at the Florida State University-headquartered National High Magnetic Field Laboratory (CSA CSM). While the National MagLab is already home to more than a dozen world-record magnets used by researchers from around the world, the future 40-tesla magnet will advance the study of quantum matter with its low-noise environment that surpasses present-day resistive and hybrid magnets.

Webb Space Telescope Will “Revolutionize Our Understanding” of the Universe

On December 25, the largest and most powerful space telescope ever constructed by NASA was successfully launched from Earth. With unprecedented technology, the James Webb Space Telescope (JWST) will peer both near and far, from the planets and bodies in our solar system to the deepest reaches of space, where the first stars and galaxies formed more than 13 billion years ago. JWST has a mirror that is 21.3 feet (6.5 meters) across, making it physically much larger than the Hubble Space Telescope and Hubble’s infrared sister telescope, the Spitzer Space Telescope, operated by Caltech’s IPAC; it also has state-of-the-art photon detectors that register a wider range of wavelengths and enable deeper and more detailed views than Spitzer.

CryoHiVac Investigates Cryogenic Market, Affordability from Earth to Space

Today’s time-sensitive market needs revolutionization of traditional costly technologies. The cryogenic and electronic market development and utilization started from 1970 for commercial applications, and both are fast-growing technologies. There has been significant advancement of electronic products. Nowadays, a small smartphone has much more data storage and processing power capability than large costly computers in the 1970s. Smartphones are now available to most people due to low cost. Due to affordable cost and high utilization factor, the electronic product demand is always increasing. In contrast, cryogenic products are exceptionally expensive, making them inaccessible to most people.

Demaco Produces ESS Hydrogen Distribution System

The ESS – Demaco Valve Box. Image: DemacoHydrogen is the most abundant chemical element in the universe and the most important feedstock for life. In Greek, the word “hydrogen” is composed of the terms “hydro” and “genes,” which means water generator. In 1766, the English chemist Henry Cavendish distinguished hydrogen from other flammable gases and identified its properties, but the name hydrogen was given by Antoine-Laurent Lavoisier in 1781. Hydrogen was commonly featured in the design of gas balloons in the 18th century, and then in the 20th century, substantial exploitation of hydrogen propellants in space propulsion systems began.

Space Cryogenic Workshop Recap

During a year filled with uncertainty, many were worried about the effects of the pandemic on CSA’s biennial Space Cryogenics Workshop (SCW). After much consideration and effort, we are pleased to report the successful execution of our first – and hopefully only – virtual SCW. Hosted virtually on the Remo® online platform on November 15 and 16, the event was two days of presentations, networking and reconnecting with colleagues and friends. Each of the two days was broken up into two groups of presentations, beginning and ending with networking opportunities in Remo’s virtual conference room. Co-chairs Amir Jahromi and Mark Kimball moderated all four sessions while CSA’s Megan Galeher and Tate Paglia – executive director and editor, respectively – worked as administrators for the sessions. Sponsors included Lake Shore Cryotronics, XMA, Lihan, Eta Space and Ability Engineering Technology, all CSA Corporate Sustaining Members.

ITER Takes First Steps Toward Cryoplant Commissioning

Every week since the beginning of November, a tube trailer filled with approximately 4,600 cubic meters (750 kg) of compressed gaseous helium delivers its load to the ITER cryoplant in the south of France. At a later stage, the deliveries will become more massive, as helium is delivered in liquid form in 25,000-cubic-meter (4-tonne) cryogenic containers. Progressively, the helium inventory in the cryoplant will reach the volume required to accommodate the different “clients” inside the tokamak: the lion’s share for the superconducting magnets and the cryogenic pumping system, a smaller percentage for the cryostat shielding.
