Necessity of mK-Cryogenics-During the past years, advances in both lithography and millikelvin cryogenics have supported and enabled vast improvement in the sophistication of experimental research on electrical circuits that display uniquely quantum mechanical behavior. It comes as no surprise that dilution refrigerator measurement systems have moved beyond basic physics research contraptions, and into central focus in the new era of quantum engineering. Achieving millikelvin temperatures remains a prerequisite for many of the leading hardware candidates for quantum computing with solid-state devices. For example, superconducting quantum circuits need temperatures low enough to keep microwave thermal photon populations on the chip negligible. In addition, the amplifiers that are typically required to achieve high-fidelity dispersive readouts are also based on superconductors and operate at the lowest noise temperatures allowed by physical limits.

Introduction-Cryogenic detectors have higher sensitivity and better energy resolution than alternative sensors, making them an attractive option for space exploration and essential for observing low energy photons in the near- or far-IR, X-ray and submillimeter ranges.[1] Since NASA’s first cryogenic missions in the early 1980s, increasingly complex space detectors have required continuous advancement in cryogenic technology.[2]

The first time I saw the first prototype of the Dylan Energy system, I thought of old Doc Brown and Back to the Future. Remember them? Doc invented something called the ‘Flux Capacitor.ʼ With the Dylan Energy system and our partners, we are capable of consuming 400 tons daily of municipal solid waste (MSW), commonly referred to as landfills, and producing 576 mW of electricity during a 24-hour period of time. This includes medical/drugs/sharpies; municipal and urban waste; industrial, pesticides and their containers; biomass; animal housing; coal; ashes from incinerators; sewage; galvanic sludge; organic sludge from petrochemical; materials with low radioactivity; used oils; batteries; tires; waste of explosive material; hazardous industrial waste; and plastics (with no restrictions).

Back to the Future movie fans may remember the term “flux capacitor” as a fictional device that allows for time travel. That device still doesn’t exist, but a University of Central Florida storage technology does use a different type of flux capacitor developed by NASA. While trying to find a way to store renewable energy (like solar and wind) and then use it when needed, UCF Pegasus Professor Jayanta Kapat and researchers Marcel Otto and Ladislav Vesely found that NASA’s Cryogenic Flux Capacitor (CFC) could be part of the solution.

Commonwealth Fusion Systems (CFS) officially opened its new campus to support the development and deployment of commercial fusion energy. The ceremonial event included visits from U.S. Secretary of Energy Jennifer M. Granholm, U.S. Senator Elizabeth Warren, U.S. Senator Edward Markey, U.S. Representative Lori Trahan, Massachusetts Lieutenant Governor Kim Driscoll, along with a host of state and local leaders.

Honeywell Aerospace is confident that an EU-funded consortium it is leading can deliver a “commercially viable” high-power fuel cell powertrain for regional aircraft applications. Ground tests of the entire 1MW propulsion system – including an electric motor – will be performed in 2026 under the Clean Aviation-backed Newborn project. Although the system will only be taken to technology readiness level (TRL) 4 – or TRL5 for most components – Ondrej Kotaba, principal scientist at Honeywell Aerospace, insists the program is focused on eventual commercial applications.

The U.S. Army Corps of Engineers Nashville District is executing a sustainability project funded by the Section 212 Program to install an upstream diffuser system at Wolf Creek on the Cumberland River in Jamestown, Kentucky. The district is partnering with power preference customers, the Southeastern Power Administration, and Tennessee Valley Authority to construct a cryogenic facility downstream of the dam and install 50,000 linear feet of oxygen diffuser lines that reach into Lake Cumberland.

With temperatures on the moon ranging from -410° to a scorching 250° F, it’s an understatement to say that humans will need habitats with heat and air conditioning to survive there long term. But heating and cooling systems won’t be effective enough to support habitats for lunar exploration or even longer trips to Mars without an understanding of what reduced gravity does to boiling and condensation. Engineers haven’t been able to crack this science – until now.

Oxford-based Tokamak Energy has built a world-first set of new generation high temperature superconducting (HTS) magnets to be assembled and tested in fusion power plant-relevant scenarios. Creating clean, sustainable fusion energy requires strong magnetic fields to confine and control the extremely hot, positively-charged hydrogen fuel, which becomes a plasma several times hotter than the sun.

On January 20, CERN celebrated the completion of the civil-engineering work for the High-Luminosity Large Hadron Collider (HL-LHC), the major upgrade of its flagship collider, the LHC. Approved in June 2016 and due to start operating in 2029, the HL-LHC will considerably improve the performance of the LHC by increasing the number of particle collisions and thus boosting the potential for discoveries. The completion of the civil-engineering work marks the start of the transition towards the HL-LHC era; the new components for the collider will be installed in the caverns and galleries that are now ready. 

Once the James Webb Space Telescope (JWST) began operations last year, the comparisons began. Astronomers and others online posted side-by-side images of the same celestial objects captured by JWST and the Hubble Space Telescope, pointing out how much crisper and more detailed those from JWST can be. But don’t count Hubble out yet. The telescope, from NASA and the European Space Agency, is still making big discoveries, after going strong for nearly 33 years.

Neutrinos mind their own business. Each second, billions of these fundamental particles will pass through stars, planets, buildings, and human bodies and will rarely ever be stopped by them, like a subatomic subway crowd. It’s why they’re often described as “ghostly” or “elusive.” "If scientists could create and capture the rare instances when these tiny and weakly interactive particles run into something, they could step into the gray area that all physicists ultimately hope to explore," said theoretical physicist Patrick Huber. "That of facts that exist outside the Standard Model of Particle Physics, beyond its explanation. Neutrinos live there, and so does dark matter."

Adding salt to a road before a winter storm changes when ice will form. Researchers at the Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab) have applied this basic concept to develop a new method of heating and cooling. The technique, which they have named “ionocaloric cooling,” is described in a paper published December 23 in Science.

The cell and gene therapy (CGT) industry achieved a significant milestone at the end of 2022: the first approval of an allogeneic T-cell therapy in the world. Following a positive recommendation from Europe’s Committee for Medicinal Products for Human Use (CHMP), the European Commission on Monday 19th December formally approved Atara Biotherapeutics’ Ebvallo (tabelecleucel) for the treatment of Epstein-Barr virus-positive, post-transplant lymphoproliferative disease in patients who have undergone at least one prior therapy. 

Jigang Wang offered a quick walk-around of a new sort of microscope that can help researchers understand, and ultimately develop, the inner workings of quantum computing. Wang, an Iowa State University professor of physics and astronomy who’s also affiliated with the U.S. Department of Energy’s Ames National Laboratory, described how the instrument works in extreme scales of space, time and energy – billionths of a meter, quadrillionths of a second and trillions of electromagnetic waves per second.

Cryomech was founded in 1963 by William E. “Bill” Gifford. Gifford was a professor at Syracuse University from 1961 to 1978 and (in collaboration with Dr. Howard O. McMahon) invented the Gifford-McMahon (GM) cycle cryo­cooler in 1957. This invention made research at very low temperatures much more accessible to the scientific community. The new GM cryocooler was affordable, easy to work with and far more re­liable than the “homegrown” equipment research institutions could build together at that time. In 1963 when Gifford began receiving requests from fellow scientists for GM cryocoolers for their labs, he founded Cryomech, Inc. – the era of cryocooler innovation began.

Since the late 1990s, advancements in communication technology and the advent of GPS expanded the desire for companies and governments to invest in satellite technologies that operate in higher orbit. Today, companies like SpaceX, Blue Origin, Virgin Orbit, Relativity Space and ULA are developing cost-effective, reusable launch systems.
