Wanted: Undergraduate Women Interested in Physics

The American Physical Society is currently accepting applications for its Conferences for Undergraduate Women in Physics, held concurrently Jan. 13-15, 2017, at universities across the US and Canada. The conferences feature workshops that encourage women to remain in STEM fields by discussing physics careers beyond academia and exposing physics majors...

KEK Opens Its Doors, Guests Tour Facility

Japan's KEK opened its doors in early September and nearly 4,000 visitors braved the late summer heat for a tour of the high energy accelerator research facility. Organizers used the event to showcase the planned International Linear Collider (ILC) project. Visitors were taken behind the scenes at two ILC test...

Worthington Introduces Carbonation Cylinders

Worthington Industries, Inc. is expanding its cryogenic technology portfolio with the introduction of a proprietary-designed beverage carbonation cylinder for industrial gas markets. The company says it designed the 500-pound beverage carbonation cylinder for use in the food and beverage markets, including restaurants, bars, movie theaters, stadiums and other locations where...

FSU Prof Explores Outer Regions of Periodic Table

In a specially designed lab at Florida State University, chemistry professor Thomas Albrecht-Schmitt studies radioactive berkelium, a little known—and difficult to obtain—element on the fringes of the periodic table that he says could help broaden the fundamental understanding of chemistry.

Air Products Celebrates Heat Exchanger Roll Out

Air Products, a leader in liquefied natural gas technology and equipment, celebrated this month the rollout of the first completed LNG heat exchanger manufactured at its new production facility in Manatee County, Florida, a 300,000 square foot space that doubles the company's manufacturing capacity.

Atlas Copco Acquires Leybold Vacuum

Atlas Copco AB has acquired Oerlikon Leybold Vacuum GmbH, a pioneer of vacuum technology founded in 1850. Renamed Leybold GmbH, the company joins the vacuum solutions division at Atlas, expanding the group to over 6,500 employees in more than 35 countries.

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...

Air Separation and Liquefaction

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...

Suppliers of regenerator materials

I was looking for suppliers of regenerator materials. Can you please provide a list of vendors for: • Lead spheres • Bronze screen discs • Rare earth materials and spheres Thank you in advance for any help you can provide.

Containing ice accumulation while recovering helium

We are implementing a system to recover helium from our Janis ST-500 continuous flow LHe cryostat. The recovery system uses standard 1/4″ plastic tubing, which we connect directly to the cryostat’s exhaust port. The problem with this setup is that the gas is still quite cold as it leaves the...
