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...

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

Effect of cryogenic freezing on tone of bell?

I have been making bells for a few years out of Bell Bronze, 87% Copper. Would cryogenic freezing have any effect on the tone of a bell if I had it treated after casting? Your help would be appreciated.

Thermal conductivity of niobium, tantalum, lead, tin

I am interested in the thermal conductivity and other properties of low temperature superconductors. Specifically I am interested in materials like Niobium, Tantalum, Lead and Tin. Would you know of a publication that dealt with thermal properties in general and also gave specific data on these materials?

Could boxes of paper records be freeze-dried?

In the event of a disaster such as a flood, could boxes of paper records be freeze-dried? Could cryogenics help in the recovery efforts?
