Oxford Instruments receives Queen’s Award for Triton™200

Oxford Instruments Nanoscience has announced that it recently received the Queen's Award for Enterprise: Innovation for the development of Triton™200, a cryogen-free dilution refrigerator with an integrated high-field superconducting magnet.

Essex Cryogenics wins $4.1 million federal contract for LOX services

Essex Cryogenics, St. Louis MO, has been awarded a $4.1 million modified federal contract by the US Air Force Material Command's Direct Reporting Unit.

Cryogenic Treatment Database is relaunched under CSA auspices

The Cryogenic Treatment Database (CTD) has been relaunched with a new, sleek look, an improved search function, and is now an official CSA Web site. The CTD was created and debuted online in 2009 to encourage scientific research in the field of cryogenic treatment by providing a public and central...

Niowave supplies two SRF cavities for Project X

Companies in the United States are rapidly learning to build the superconducting radio-frequency cavities Fermilab needs for future accelerators such as the proposed Project X and the International Linear Collider.

Fermilab crews work on beamline vacuum system for New Muon Lab

From Fermilab Today: It is perhaps fitting that the New Muon Lab, a long, low concrete affair facing open fields, sits facing the northern edge of Fermilab’s property.

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...

Cryogenic Treatment of Materials

F.J. Diekman Controlled Thermal Processing, Inc. info@metal-wear.com Cryogenic Processing (also called cryogenic treatment, and incorrectly “cryogenic tempering”) is a process that uses cryogenic temperatures to modify materials to enhance their performance. Cryogenic Processing involves the slow reduction in temperature of the material to at least -300°F (-185°C) and holding the...

Cryogenics in Space

Peter Kittel University of California-Berkeley pkittel@cal.berkeley.edu Space Cryogenics is the application of cryogenics to space missions. These applications fall into two broad areas, supporting space science missions and supporting the space transportation infrastructure. Science applications: The atmosphere is opaque to much of the electro-magnetic spectrum. In space, the absence of...

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...

Separated layers of ice over a pipe

I want to know that why there are different layers of ice over a pipe carrying a cryogenic fluid, each layer separated with clear marks / lines? What do these layers signify?
