Cold Facts Digital – The go-to place for Cryogenics and Superconductivity

Hahn Shot First

After 32 years as Fermilab’s staff photographer, Reidar Hahn is retiring – and saying farewell with a final collection of photos in Fermilab’s art gallery. Hahn has graciously allowed CSA to display some of his best work in future issues of Cold Facts and a CSA online photo gallery.

Woman Hospitalized, Loses Gallbladder After Drinking Liquid Nitrogen at Florida Hotel

A woman is suing The Don CeSar Hotel in St. Pete Beach FL after allegedly being served liquid nitrogen in her drinking water causing her to be rushed to the hospital for an emergency gallbladder removal and partial stomach removal. Stacey Wagners filed the suit on October 11, nearly one...

Cool and Dry: A Revolutionary Method for Cooling a Superconducting Accelerator Cavity at Fermilab

For the first time, a team at Fermi National Accelerator Laboratory (CSA CSM) has cooled and operated a superconducting radio-frequency cavity—a crucial component of superconducting particle accelerators using cryogenic refrigerators—with cryocoolers, breaking the tradition of cooling cavities by immersing them in a bath of liquid helium. It achieved an accelerating...

Department of Energy Authorizes LNG Exports from the Venture Global Plaquemines Project

The US Department of Energy issued an order to Venture Global Plaquemines LNG, LLC approving exports of domestically produced liquefied natural gas from the Plaquemines LNG Project. The project will be located on the Mississippi River, in Plaquemines Parish LA approximately 20 miles from the port of New Orleans. Under...

Hyundai Reveals New Concept for Hydrogen Powered Fuel Cell Electric Truck

Hyundai Motor Company has revealed the first rendering images of its new concept for a hydrogen powered fuel cell electric truck, the HDC-6 NEPTUNE. It will debut its new commercial truck concept during the North American Commercial Vehicle Show in Atlanta this month.

US ATLAS Phase I Upgrade Completed at CERN

The ATLAS experiment at CERN’s Large Hadron Collider (LHC) is ready to begin another chapter in its search for new physics. A significant upgrade to the experiment, the ATLAS Phase I Upgrade, has received Critical Decision-4 approval from the US Department of Energy, signifying the completion of the US portion...

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...

You are encouraged to read Cryo Central’s History...

Bose-Einstein Condensate

A Bose-Einstein condensate, first proposed in 1925 by Albert Einstein based on work done by Satyendra Nath Bose (the same Bose from whom the term boson is derived), is a super-cold state of matter in which almost all of the individual atoms have “condensed” down to the lowest possible quantum...

Cold Technology for Pest Control

While it does not reach temperatures cold enough to be called cryogenic, carbon dioxide snow is at the heart of a new way of dealing with unwanted pests. It utilizes a quick freezing process that takes advantage of the properties of carbon dioxide snow and has a number of benefits...

Cryogenic Finishing

The following 3 articles discuss the uses and procedures of various type of cryogenic finishing. 1) By Robin A. Rhodes, Cryogenic Institute of New England, Inc. rrhodes@nitrofreeze.com Cryogenic Deflashing is employed to remove undesired residual mold flash that remains on molded parts after they are removed or ejected from the...

Specs and info on turbo expanders

I am a fourth year chemical engineering student doing a design project for the liquefaction of natural gas to DME and we are using a turbo expansion unit. I was wondering whether you would send me some specs and any additional information on turbo expanders that I could use as...

Colleges that offer cryogenic studies

Would you happen to know of any colleges in the US that offer cryogenics as a major? If not, should I major in something like biology or physics before, then branch off to the field of cryogenics? Any information that you could give me would be greatly appreciated, considering this...

Sudden loss of vacuum in LHe storage dewar

I’m trying to find data on what happens when a 100 Liter LHe storage dewar experiences a catastrophic failure such as a sudden loss of vacuum. If anyone has any info on this subject, it would be very helpful.

Data on hardness of Indium?

Where can I find experimental data on the hardness of Indium, as a function of temperature, as well as any existing data on the thermal contact conductance of junctions containing Indium foil, also as a function of temperature?
