Technifab Restructures, Announces Three Divisions

Technifab Products, Inc. (CSA CSM) has announced organizational changes, segmenting its business into three distinct divisions—Technifab Cryogenics, Technifab CNC Manufacturing and Technifab Cryodewars.

Density of Electron Pairs Key to Cuprate Superconductivity

Physicists at the US Department of Energy's (DOE) Brookhaven National Laboratory have determined a new reason for why cuprates become superconducting at high temperature. After growing and analyzing thousands of samples of a cuprate known as LSCO for the four elements it contains (lanthanum, strontium, copper and oxygen), the team...

Major Experiments Update Results at ICHEP2016

Researchers from several of the world's major institutions made announcements during the 38th International Conference on High Energy Physics, including physicists working at CERN, the T2K Collaboration and Fermi National Accelerator Laboratory (CSA CSM).

New Material Discovery Allows Study of Elusive Weyl Fermion

Researchers at the US Department of Energy's Ames Laboratory have discovered a new type of Weyl semimetal, a material that opens the way for further study of Weyl fermions, a type of massless elementary particle hypothesized by high-energy particle theory and potentially useful for creating high-speed electronic circuits and quantum...

Sting vs. MRI, Don’t Scan so Close to Me

Researchers at Canada's McGill University didn't turn on a red light, but managed nevertheless to lure musician Sting into a lab for an unusual neuroscience study based on his brain scans. The findings, published in the journal Neurocase, offer insights into how gifted individuals find connections between seemingly disparate thoughts...

O, Canada! Tips on CRN and International Code

Companies exporting to Canada must obtain a CRN, or Canadian Registration Number—issued by a Canadian provincial government such as Ontario (TSSA), Alberta (ABSA) or British Columbia (BC)—before shipping products to Canadian clients. It’s a process that can take from three to six months, and it is one that is often...

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...

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?
