Cold Facts Digital – The go-to place for Cryogenics and Superconductivity

First LHC magnets prepped for restart

One-eighth of the Large Hadron Collider (LHC) dipole magnets have reached the energy they'll need to operate in 2015. Engineers at CERN powered 154 superconducting magnets to a current of around 11,000 amps. This is about 1,000 times greater than an average household appliance and is required to make the...

Save the Date for the 2015 Space Cryogenics Workshop

NASA Glenn Research Center announces the 2015 Space Cryogenics Workshop (SCW), a division of the Cryogenic Society of America. All aspects of space cryogenics will be represented, with an emphasis on work related to previous missions as well as future research.

CSA Board Certifies Newly Elected Directors

At the August 14 CSA Board meeting held during the Applied Superconductivity Conference in Charlotte NC, the four directors recently elected by the society's membership were certified.

Superconductivity: Will It Be Coming in from the Cold?

Dr. Paul Michael Grant assesses the application of superconductivity within the electric power sector, asking, "Is there a 'hot track' upward for both applications of today's superconductors and future transition temperatures beyond 200K as well?"

ASC Attendees Spend Event-Filled Week

This year’s Applied Superconductivity Conference, ASC14, hosted 1,523 attendees from 36 countries, with 791 papers submitted for peer review. Held at the Charlotte NC Convention Center, August 10-15, the event’s theme was “Race to Energy Efficiency,” incorporating the racecar theme of its proximity to the NASCAR Hall of Fame, which...

Historical Retrospective: CSA’s Birth in the Early Days of the Space Age

We’ve always heard that CSA began in 1964 with the growing need for cryogenics in the burgeoning Space Age. We decided to take a look at the unfolding of this phenomenon in the pages of Cryogenic Technology, “the Journal of the Cryogenic Society of America,” Volume 1, 1964-1965.

Helium II

Helium II (He II) refers to the second liquid phase of the most abundant helium isotope (4He). Helium II is also referred to as superfluid helium. Helium II occurs once the temperature of the liquid helium drops below 2.17K. The phase transition between the first liquid phase of Helium (referred...

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...
