JanisULT, Formerly Janis Research, Launches New Website

In August 2020, Janis Research Company, LLC (CSA CSM) announced a formal change in company name to JanisULT (a trading name of American ULT Cryogenics, LLC) following the successful sale of their laboratory cryogenics business to Lake Shore Cryotronics (CSA CSM). On March 12, the company announced their updated website,...

IceCube Detection of a High Energy Particle Proves 60-Year-Old Theory

On December 6, 2016, a high energy particle called an electron antineutrino hurtled to Earth from outer space at close to the speed of light carrying 6.3 petaelectronvolts of energy. Deep inside the ice sheet at the South Pole, it smashed into an electron and produced a particle that quickly...

From Second Sound to Music: A Special Composition Inspired by Advanced Physics

CSA Board Chairman, Dr. John Weisend II, and composer M.E. Edgerton present a unique representation of advanced physics with a one-of-a-kind musical arrangement based on data produced from advanced particle accelerators.

Improving Cryogenic Pipes to Reduce Wasted Energy, Money at BRUGG

BRUGG (CSA CSM), a leading cryogenic piping company based in Wunstorf, Germany, engineers pipe systems for various industrial applications while minimizing heat leak and saving resources—monetary and otherwise. Where BRUGG’s low temperature applications are only one part of a larger product portfolio, the vast temperature differences between cryogenic and ambient...

MLI Blankets from Web Industries Improve Commercial Space Offerings

Needs for custom-made, space proven components and systems take on added urgency as launch dates proliferate and space facilities around the world hum with activity. Supply partners like Web Industries (CSA CSM) that offer such components can support space initiatives and help space and satellite companies meet ever-tightening launch deadlines....

Latest in Defining Cryogenics

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...
