Is magnetic cooling the future of cool?

Ames Laboratory scientists almost 20 years ago announced groundbreaking progress in magnetic refrigeration and yet there are still no known commercially available products that use a magnetic cooling system. Magnetic cooling exploits the magnetocaloric effect, a temperature change of a material caused by exposing it to a changing magnetic field,...

New atomic absorption spectrometer helps redefine the kelvin

A team of Australian scientists has developed an atomic absorption spectrometer that provides a new way to determine Boltzmann’s constant, a number that relates the motion of an individual atom to its temperature. The research, published in Nature Communication contributes to a worldwide scientific effort to redefine the kelvin, the...

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...

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...

Containing ice accumulation while recovering helium

We are implementing a system to recover helium from our Janis ST-500 continuous flow LHe cryostat. The recovery system uses standard 1/4″ plastic tubing, which we connect directly to the cryostat’s exhaust port. The problem with this setup is that the gas is still quite cold as it leaves the...
