SkyWater Unveils Cryo Lab, Partners with FormFactor for Advanced RTS Noise Detection in ROIC Applications

SkyWater Technology announced earlier this year the establishment of a new cryogenic lab dedicated to characterizing random telegraph signal (RTS) noise for read-out integrated circuits (ROICs). This move is aimed at addressing the crucial need to mitigate RTS noise in order to enhance image quality and performance for ROIC customers...

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

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...

NASA Rocket Hardware Prepped for Shipment to Space Coast

With Artemis teammates and media watching, United Launch Alliance (ULA) crews guided the interim cryogenic propulsion stage (ICPS) for NASA’s SLS (Space Launch System) rocket for Artemis III to the loading dock at ULA’s facility in Decatur, Alabama, July 31. ULA’s R/S RocketShip will transport the flight hardware to ULA’s...

Contract Awarded for Acquisition of Large Cryogenic System for DUNE Detectors in South Dakota

A significant milestone has been achieved in the realization of the Deep Underground Neutrino Experiment (DUNE) with the awarding of a multi-year contract for the acquisition of a large cryogenic plant. This plant will be responsible for cooling tens of thousands of tons of liquid argon, bringing the ambitious experiment...

Cryogenics at FAIR: Adaptability is Key

The Facility for Antiproton and Ion Research (FAIR) in Darmstadt, Germany, represents an ambitious reimagining of the GSI Helmholtz Center for Heavy Ion Research, one of Europe’s leading accelerator research laboratories. When it comes online for initial user experiments in 2027, FAIR will provide scientists from around the world with...

Green Hydrogen Facility May Be Coming to NY

A new green facility may be coming to Massena, NY. Air Products, an industrial gas supply company, has proposed a green hydrogen facility in Massena, according to a press release from C&S Engineers. This facility would produce liquid hydrogen by electrolysis to be used as a renewable fuel source. Project...

Latest in Defining Cryogenics

Refrigerators and Liquefiers

Two of the most common terms used in cryogenics are “refrigerator” and “liquefier.” These terms describe similar and, as will be seen, in some cases identical components. A refrigerator provides cooling (that is, absorbs heat) at cryogenic temperatures. Refrigerators typically put a working fluid (such as helium) through one of...

Air Separation

Air separation is one of the largest, as well as earliest, industrial applications of cryogenics. In this process, cryogenic temperatures are used to separate air into its constituent gases: nitrogen (78.08%), oxygen (20.95%), argon (0.93%) and carbon dioxide (0.3%). Trace gases such as krypton, neon, xenon and helium total far...

Coefficient of Performance and Figure of Merit

The coefficient of performance (COP) is used to describe the effectiveness of refrigerators, including those operating at cryogenic temperatures. The COP is defined as the amount of heat removed at the cryogenic operating temperature of the refrigerator divided by the amount of work that must be applied to remove the...

Food Processing

Cryogenics and Food The industrial gas industry provides a host of products and services related to food. The various gases have useful and sometimes fascinating applications in food industry. “The food industry is not a homogenous industry. The needs of customers processing hamburger vs. poultry vs. strawberries vs. seafood, for...

Primary Standards

Elie K. Track Hypres, Inc. elie@hypres.com http://www.hypres.com/ Primary standards involve the exact definition and realization of units of measurement for various quantities, time, length, mass, voltage, resistance, current, etc. International agreements based on the latest scientific knowledge define those units, and their realizations vary depending on the unit itself. For...

Shrink Fitting

Robin A. Rhodes Cryogenic Institute of New England, Inc. rrhodes@nitrofreeze.com Shrink fitting, (or “compression fitting” as it is sometimes called), is a method used to insert a pin or bushing into a housing or other assembly requiring an extremely tight tolerance fit. It can be used as an alternative to...

Telecommunications

From the Winter 2004 issue of Cold Facts magazine The recent M-Calc IV — 4th Industry Assessment workshop discussing military and commercial applications for low-cost cryocoolers, held in November in San Diego, highlighted progress being made in cryogenics as applied in telecommunications. The reliability and long lifetime of projects now...

An Issue of Pressure and Flow Rate in a Supply Tank

Please help solve this problem: A supply tank requires a vaporizer to generate sufficient pressure to pump stored fluid up into a vehicle or tank. The available head is limited as the tank level falls and it is important to minimize the system pressure drop to maintain the desired flow...

Using MLI on VJ Line Joints or Cryo Storage Tanks

When installing Multi Layer Insulation (MLI) blankets on VJ line joints or cryo storage tanks should they be wrapped and tied down tight or loose? These are usually pre-cut to size. Also should they have an access hole at the point of where the molecular sieve is installed to help...
