KEYCOM Celebrates 30 Years of Worldwide Industry Standards

Low noise amplifier for cryogenic applications. Credit: KEYCOMThe computing elements of a quantum computer can only be operated properly when they are free of electronic noise. In order to achieve this state, it is necessary to realize an ultralow temperature environment in the millikelvins at a minimum. However, it is not enough to simply provide a dilution refrigerator. It is essential to install coaxial cables that can be used under cryogenic conditions to facilitate the input and output of microwaves to and from the cryocooler. KEYCOM offers a variety of coaxial cables with low thermal conductivity (made of niobium titanium, copper nickel, beryllium copper or stainless steel) for use covering cryogenic and room temperatures.

Blood Banks: Cryogenic Blast Freezing to -90°C in Minutes Increases Throughput

Reflect Scientific B-90 blast freezer 1.jpgBlood banks utilize freezers to rapidly freeze and store a range of thermally sensitive products such as blood plasma and cryoprecipitate. However, conventional compressor-based freezers can take hours to reach the ultra-low target temperature, slowing processing to a level that may not be sufficient for many operations. The challenge is that mid- to large-volume blood banks may need to process and freeze from 500 to 2,000 units a day. This can create a “production bottleneck” when the donor blood is brought in at the end of the day.

Got Propane?

Image Credit: Propane Education & Research CouncilAs the maritime industry mulls the ‘fuel of the future,’ a strong and growing case can be made for propane based on availability, cost and ease of use compared to competitive fuels. Darren Monzingo, president of FARO Industrial and VP of Engineering for GEM Marine, is a marine engineer and naval architect, and through his work, he’s gained exposure to propane as an industrial fuel. While the maritime industry is prioritizing using CNG/cryogenic fuels, through his research Monzingo noticed that propane is an easy-to-use, readily available energy source of fuel that accomplishes ship fleet needs for productivity, energy expenditure, and emissions reduction. Importantly, he notes that if a vessel is ‘LNG-Ready’, it is ‘Propane-Ready’.

Trenta's Final Fusion Test Campaign

TrentaIn 2023, Helion Energy, Inc., an American fusion research company, will end operations on Trenta, its 6th fusion prototype. The team is now undergoing Trenta’s last-ever fusion test campaign. For two years, its scientists and engineers have carried out rigorous research to test the capabilities of this fusion machine. The Helion team’s results suggest that Trenta is currently the best performing privately funded fusion machine in the world. After these last weeks of plasma operations under vacuum, Helion will retire Trenta and move all focus to Polaris, its 7th fusion prototype, expected to demonstrate net electricity in 2024.

CryoEdge Solves an Ancient Problem with a Cutting-Edge Solution

Cryo EdgeEver since the Stone Age, people have searched for the most effective ways to cut and shape materials for best use. This quest has most recently resulted in revolutionary breakthroughs and developments like lasers, plasma beams, and water jets as cutting instruments. Despite these advances, the overwhelming majority of cutting tasks still require metal with a sharpened edge, which has one key undesirable trait: it wears out and gets dull. Not so with CryoEdge, a sales and service company based in the Spokane, Washington area. CryoEdge’s essential issue goes back to prehistoric times: how can we cut things better and make the tools we use for cutting last longer?

How to Avoid a Tank Collapse

https://cryo.memberclicks.net/assets/Example-of-Vacuum-Collapse.jpgThe industrial gas industry produces the elemental components of “air” (nitrogen, oxygen, and argon) that are used in other industries as part of their processes. Once separated from air, each element exists as an extremely cold cryogenic temperature liquid. Typical liquid temperatures are −185° C. Large, field-erected tanks are used to store these liquids, and these tanks range from 100,000 gallons to over 2,000,000 gallons in size. API-620/Appendix Q standards, or their equivalent, are the routine guiding design documents. These tanks are built as flat-bottom, domed-top tanks, typically with stainless steel inner containers, carbon-steel outer containers, and the top/side insulation space between these tanks filled with three to five feet (radial dimension) of granular perlite insulation. The inner tank sits on a sandwich structure of Foamglas® insulation and concrete. During cooldown and commissioning, these tanks need to be dried, inerted, and brought down to very cold temperatures to allow product to be introduced. If done incorrectly during cooldown, these tanks risk vacuum collapse. This article discusses the details surrounding one such occurrence.

Off-Grid Hydrogen Energy Maximizes Power of Steam

Dylan Energy R and DDylan CHP LLC has researched, developed, and patented advanced steam generation technology, utilizing hydrogen to generate clean energy electricity. The Dylan System is based on extreme heat preservation (EHP), the heart of the Dylan patent that allows the Dylan Energy-Efficient System to achieve nameplate steam output while consuming only a small fraction of the hydrogen. Dylan’s flexible EHP technology can easily be retrofitted to burn other fuels including natural gas, LNG, flare gas, landfill gas, MSW, or other traditional fuels as feedstock that more conventional systems require. Dylan continues to engineer its system to maximize quality, energy efficiencies and reliability to its customers.

Paragraf is Changing the Game with Cryogenic Hall Sensors

Paragraf GHS mounted on an Oxford Instruments‘ Proteox development fridge. Credit: ParagrafDue to limitations in size and power dissipation, many prevalent measurement methods are incompatible with low temperature applications. Hall effect sensors have emerged as the superior option because of their compact size and low-power requirement. Until now, conventional Hall sensors have themselves been limited by material capabilities and the quantum Hall effect (QHE). Paragraf®’s Cryogenic Graphene Hall Sensors (GHS-C), however, enhance the ability of companies that make and/or use superconducting magnets to conduct continuous measurements in low temperature and high-field environments. This means ending the reliance on factory calibration or current-to-field measurements to evaluate these systems. With its patented graphene deposition process, Paragraf averts limitations by producing the GHS-C, which achieves operation in temperatures down to mK and field measurements of over 30 T.
