The LSST Camera Set to Unveil the Cosmos

The completion of the Legacy Survey of Space and Time (LSST) Camera, after two decades of collaborative work involving scientists and engineers at the Department of Energy’s SLAC National Accelerator Laboratory and international partners, signifies a significant milestone in the construction of the Vera C. Rubin Observatory in Chile. The...

Scientists Uncover a Hidden Electronic State

Research often unfolds as a multistage process. The solution to one question can spark several more, inspiring scientists to reach further and look at the larger problem from several different perspectives. Such projects can often be the catalyst for collaborations that leverage the expertise and capabilities of different teams and...

Review of John Weisend II’s Superfluid – How a Quantum Fluid Revolutionized Modern Science

Over the recent holidays, we hosted some new friends in our home. The young couple are both technically savvy but have never previously encountered the world of cryogenics, low temperatures, or superfluid helium. I had a copy of John Weisend II’s new book Superfluid – How a Quantum Fluid Revolutionized...

Two-Phase Flows

Two-phase flows are those flows in which there is a mixture of two physical states (solid, liquid or vapor). In cryogenic applications, such flows are almost always a mixture of a cryogenic liquid along with its corresponding vapor. A mixture of liquid helium and helium vapor would be a typical...

Supercritical Fluids

A supercritical fluid is defined as a substance whose temperature and pressure exceed those of its critical point. Every pure substance has a critical point that is defined in thermodynamic space by a critical temperature and a corresponding critical pressure. For example, the critical point for helium has a critical...

Brayton Cycle

The Brayton cycle is one of the many thermodynamic cycles used to generate cooling at cryogenic temperatures. Strictly speaking, when referring to cooling we should call this the reverse Brayton cycle as the original Brayton cycle describes the process of power generation or propulsion via a gas turbine. In many...

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

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...

Data on thermal expansion down to 40K

For our cold mechanics, we use ball bearings from ADR from stainless steel which is AISI 440C, DIN X105CrMo17, W.Nr. 1.4125. Does anyone know the data of thermal expansion of this material down to 40 K?

Difference between radar and servo gauge for LNG tanks?

What is the difference between radar and servo gauge for LNG tanks? How do I understand the gauging system for LNG tanks and choose the best one?

Materials for "cryogenics in spacetech"?

I had to take a seminar in a national competition that is to be held in our country on the topic “cryogenics in spacetech.” For this, I need some materials related to it, and I thought to approach you for help. Can you suggest some relevant materials?
