Liquid Hydrogen

Hydrogen becomes a liquid at 20K and 1 bar. Liquid hydrogen (LH2) is an important substance in industry, transportation and research. Industrial uses of hydrogen include applications in the electronics, glass, chemical and metal processing fields. In these applications, the hydrogen is generally used as a room temperature gas but...

Superconducting Radiofrequency Cavities

Superconducting radio frequency (SRF) cavities represent an important application of cryogenics and superconductivity. SRF cavities are a technology for accelerating charged particle beams via the transfer of radiofrequency (RF) energy to the beams via resonant structures. As such, they are frequently found in large particle accelerators used for scientific research....

Thermal Radiation Shields

Actively cooled thermal radiation shields are a common feature of cryostats whose lowest temperature is less than 77K. These shields, which typically operate at temperatures between that of LN2 and 40K, block thermal radiation from higher temperatures from reaching lower temperature cryogenic components or fluids. Since the heat radiated from...

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...

Seeking technical publication that explains the science behind the cryogenic treatment of aluminum

Would you know of a technical publication that would list the benefits and explain the science behind the cryogenic treatment of aluminum, specifically a 356-T6 aluminum cylinder head casting? Eddie Phillips

Source of emissivity data for aluminum and aluminized Mylar at room temperature, 77K and 4.2K

Can anyone recommend a source of emissivity data for aluminum and aluminized Mylar at room temperature, 77K and 4.2K? Also, I would be interested in finding a facility that can measure this information. Any information will be greatly appreciated. William Einziger, GE Healthcare

Looking to purchase new LN2 freezer: any suggestions?

I will be purchasing a new liquid nitrogen freezer soon, but I am limited by space restrictions. The freezer cannot be more than 38 inches wide. However, it would be beneficial if the freezer holds a high number of racks such as 24. In addition, we prefer not to purchase...

Affordable flow meter to measure LN2 flow through a pipeline

I am trying to find out if anyone knows of or has used an affordable flow meter that can measure liquid nitrogen flow through a pipeline. It doesn’t need to be very accurate as it’s really to allow people in different departments to allocate cost rather than for scientific measurement....
