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....
Manufacturer for a machine to liquefy natural gas or methane gas.
I’m in search of a company to manufacture a machine to liquefy natural gas or methane gas.
Need a plastic for diffuser on the magnet end of a LHe fill siphon
I am trying to select a plastic to be used as a diffuser on the magnet end of a LHe fill siphon. Can you recommend anything that will hold up at LHe temps? I have seen some and they look like HDPE or Polypropylene but I am not sure.
Thermal conductivity orthotropic properties from 300K up to 500K
I am looking for the thermal conductivity orthotropic properties from 300K up to 500K (or even higher, if available). “Cryocomp” provides orthotropic data on G-10 (Fill, Warp, Normal) only up to 300K.
Looking for heat conductivity values of CuCrZr in the low temperature range of 4 to 300K
I’m a student of physical engineering and I am looking for heat conductivity values of CuCrZr in the low temperature range of 4 to 300K. Jakub Voňka Brno University of Technology Faculty of Mechanical Engineering
