Can LH2 Preserve Our Last Clean Continent?

Antarctica is vital for cold research, from understanding our fragile climate to tracking local fauna. Energy is critical to this research as it supports expeditions and heating bases. Reliance on diesel import is leaving a dark legacy on the continent, as the buildup of black carbon is causing accelerated rates...

Commonwealth Fusion Cryo Team’s Just-in-Time Engineering

High temperature superconducting (HTS) tapes, which have emerged over the last decade, are enablers for new technologies. Specifically, high temperature superconducting magnets to enable commercial fusion energy are arguably the most tantalizing and potentially impactful. Fusion energy would be a long-envisioned source of firm, safe, carbon-free electricity whose successful development...

Adiabatic Demagnetization Refrigeration

Reaching temperatures below 1K requires different techniques than the various helium gas cycles found in large scale refrigeration plants and small cryocoolers. One of these techniques is Adiabatic Demagnetization Refrigeration (ADR). This technique takes advantage of the fact that the entropy of paramagnetic materials in a magnetic field is lower than...

Cryogen-Free

A cryogen is any fluid that operates at cryogenic temperatures (below roughly 150K – 120K). Using this definition, helium gas at 40K is a cryogen. Another more restrictive definition is to use cryogen to refer specifically to liquids at cryogenic temperatures. This is generally how it is used in the...

Cryostats and Cryocoolers

A cryostat is any device designed to maintain things (including fluids) at cryogenic temperatures. In general usage, cryostats tend to be passive devices rather than providing active cooling. In this usage, cryostats keep things cold by thermally isolating them from room temperature. This generally is accomplished by a combination of...

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...
