Chart Industries, Inc. has announced that its Distribution & Storage ("D&S") business in China has been awarded a contract to provide self-contained liquefied natural gas (LNG) station modules to Kunlun Energy Investment, a wholly owned subsidiary of PetroChina's Kunlun Energy.
Report on ICCR2013 in Hangzhou, China
Held at Zhejiang University, Hangzhou, China, April 6-9, the 5th International Conference on Cryogenics and Refrigeration (ICCR2013) attracted more than 330 participants from 17 nations and areas, with 220 papers presented.
Inside Fermilab’s New Strand and Cable R&D Lab
The mission of the Superconducting Strand and Cable R&D program is to understand and improve scientific and engineering aspects of superconducting strands and cables for accelerator magnets, including dipoles, quadrupoles and solenoids. Since 1998, the lab has also served as the ideal experimental environment for 30 graduate students in physics...
Cold Facts Tours NHMFL, ASC and CAPS
In February of this year, CSA was invited to the National High Magnetic Field Laboratory (CSA CSM) at Florida State University to tour its facilities and meet key personnel at the forefront of cryogenic and superconducting technology at the lab. On our tour we were taken behind the scenes to...
Does Cryogenic Electronics Have a Role in Electric Power?
Electric power systems—whether for electric utilities or on ships, airplanes or automobiles—require electronic power circuitry to change voltage levels and to convert between DC and AC, as well as for controlling power delivery. The use of superconductivity and cryogenics for motors, generators, energy storage and power distribution leads naturally to...

Dewar
A dewar is a type of cryostat named after Sir James Dewar, the researcher who first developed the concept of a vacuum insulated container with silvered walls to reflect thermal radiation. Dewar was the first to liquefy hydrogen, and he created the device to store his discovery. The thermos bottle...
Stirling and Gifford-McMahon Cryocoolers
Stirling and Gifford-McMahon (GM) cryocoolers are two of the most commonly used cryocoolers in cryogenics. Both devices have a significant industrial base and operate at a wide range of temperatures and capacities. The thermodynamic cycles for both of these cryocoolers are quite similar. The Stirling cycle consists of a compressor,...
Liquefied Natural Gas (LNG)
A significant commercial application of cryogenics is the liquefaction, transport and storage of natural gas. Liquefied Natural Gas (LNG) is generally 95 percent methane with a few percent ethane and much lower concentrations of propane and butane. LNG liquefies at 111.6 K. Unlike many applications of cryogenics, the motivation for...
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....
Need help comparing chest freezers and upright freezers
Currently we use in our Biobank an upright -80 freezer to store all our samples. We are planning to buy a fully automated bio-repository storage that will do the picking of samples under restricted conditions. But in the meantime I foresee that we have to pick the samples manually. The...
Need recommendations for cryogenic vials
I am looking into standardizing our range of bio storage tubes (cryogenic vials). These will be for both blood and tissue samples and their derivatives. Any recommendations, comments on Micronics, Nalgene, Nunc and or others that are suitable for long term -80 C and -196 C storage, DNA/RNA suitable, would...
We need a custom machine for flash freezing of water
We are an ice making company and have started a new project, which is related to flash freezing of water. It is based on cryogenics technology and we need a custom made machine. I would kindly ask you to pass me a few companies who would be interested in such...
Looking for a pump suitable for cold liquids
I would like to construct a small cooling circuit (appr. 50 x 50 cm) pumping liquid at a temperature down to -120°C from a cold reservoir to the specimen to be cooled. The tubes and connections are not a problem, but does somebody know a pump (suction/compression for circulation) suitable...
