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...

Demaco Produces ESS Hydrogen Distribution System

Hydrogen 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,...

Ability Engineering Technology Introduces Ultra Precise Cryo Valve to Public

Ability Engineering Technology (AET), an Illinois-based manufacturer of equipment used in cryogenic process applications, has announced the introduction of a standard product line of Cryogenic Valves. According to Matt Resler, Sales Director at AET, “Our cryogenic valves have been successfully used for more than 30 years by our DOE clients, and...

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®...

Fermilab Sees Record Performance from Next-Generation Accelerator Componen

For several years, three US Department of Energy national labs have worked together to further improve state-of-the-art particle accelerator technology. First tests of a prototype built at Fermi National Accelerator Laboratory (Fermilab, CSA CSM) show the effort has paid off, with a new component setting records. The technology under development...

Transfer Lines

Transfer lines may in some real sense be thought of as the cryogenic fluid analogy of current leads. While current leads carry electrical power to where it’s required in a cryogenic system, transfer lines do the same with cryogenic fluids. Transfer lines range in complexity from very simple U-tubes containing...

Zero Boiloff

Zero Boil Off cryostats are those that contain liquid cryogens but are designed to eliminate or vastly reduce the boil off of  the liquid. These cryostats combine some of the advantages of Cryogen-Free systems (e.g. ease of use and long operational lifetime) with the advantages associated with a reservoir of liquid...

Cryomodule

Cryomodule is a term that is most commonly used to refer to cryostats that contain superconducting radio frequency (SRF) cavities. Such cavities are used to accelerate charged particle beams and are a major component of modern particle accelerators. Using the term cryomodule to refer to cryostats containing SRF cavities appears...

Magnetic Levitation

From http://www.superconductors.org. Magnetic-levitation is an application where superconductors perform extremely well. Transport vehicles such as trains can be made to “float” on strong superconducting magnets, virtually eliminating friction between the train and its tracks. Not only would conventional electromagnets waste much of the electrical energy as heat, they would have...

Superconductivity

From Superpower website. History of Superconductivity Superconductivity was discovered in 1911 by the Dutch physicist, Heike Kammerlingh Onnes when he was able to liquefy helium by cooling it to 4 Kelvin, or -452°F. This enabled him to cool other materials close to absolute zero and investigate their electrical properties. He...

Medical Applications of Cryogenics

Neutron Therapy Cryogenics is at the heart of nuclear accelerators. Accelerators such as Fermilab’s Tevatron make neutron therapy for cancer possible. From Fermilab Today 4/20/09: Fermilab currently offers neutron therapy. But staff at Fermilab designed and built the proton accelerator used by the nation’s first hospital-based treatment center to use...

Nuclear Physics

Al Zeller National Superconducting Cyclotron Lab (NSCL) at Michigan State University zeller@nscl.msu.edu Cryogenics has a long history in nuclear physics. The technology has its origins in the use of cold traps for maintaining a vacuum, which is required to prevent beam loss and for generating high voltages used in acceleration....

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...
