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.

Dewar

A dewar is a type of cryostat named after Sir James Dewar, the researcher who first developed the concept of a vacuum insulated container with silvered walls to reflect thermal radiation. Dewar was the first to liquefy hydrogen, and he created the device to store his discovery. The thermos bottle...

Stirling and Gifford-McMahon Cryocoolers

Stirling and Gifford-McMahon (GM) cryocoolers are two of the most commonly used cryocoolers in cryogenics. Both devices have a significant industrial base and operate at a wide range of temperatures and capacities. The thermodynamic cycles for both of these cryocoolers are quite similar. The Stirling cycle consists of a compressor,...

Liquefied Natural Gas (LNG)

A significant commercial application of cryogenics is the liquefaction, transport and storage of natural gas. Liquefied Natural Gas (LNG) is generally 95 percent methane with a few percent ethane and much lower concentrations of propane and butane. LNG liquefies at 111.6 K. Unlike many applications of cryogenics, the motivation for...

Magnetic Levitation

From http://www.superconductors.org. Magnetic-levitation is an application where superconductors perform extremely well. Transport vehicles such as trains can be made to “float” on strong superconducting magnets, virtually eliminating friction between the train and its tracks. Not only would conventional electromagnets waste much of the electrical energy as heat, they would have...

Superconductivity

From Superpower website. History of Superconductivity Superconductivity was discovered in 1911 by the Dutch physicist, Heike Kammerlingh Onnes when he was able to liquefy helium by cooling it to 4 Kelvin, or -452°F. This enabled him to cool other materials close to absolute zero and investigate their electrical properties. He...

Medical Applications of Cryogenics

Neutron Therapy Cryogenics is at the heart of nuclear accelerators. Accelerators such as Fermilab’s Tevatron make neutron therapy for cancer possible. From Fermilab Today 4/20/09: Fermilab currently offers neutron therapy. But staff at Fermilab designed and built the proton accelerator used by the nation’s first hospital-based treatment center to use...

Nuclear Physics

Al Zeller National Superconducting Cyclotron Lab (NSCL) at Michigan State University zeller@nscl.msu.edu Cryogenics has a long history in nuclear physics. The technology has its origins in the use of cold traps for maintaining a vacuum, which is required to prevent beam loss and for generating high voltages used in acceleration....

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...
