Maglab Launching New Zine for Scientists, Nerds and Other Clever People

The National High Magnetic Field Laboratory (CSA CSM) is getting back in the publishing business with a new science magazine set to launch in 2017. Tentatively titled Mag/zine, the publication will focus on high magnetic field research, targeting both scientists and science-interested readers. It is set to publish three or...

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.

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...

Food Processing

Cryogenics and Food The industrial gas industry provides a host of products and services related to food. The various gases have useful and sometimes fascinating applications in food industry. “The food industry is not a homogenous industry. The needs of customers processing hamburger vs. poultry vs. strawberries vs. seafood, for...

Primary Standards

Elie K. Track Hypres, Inc. elie@hypres.com http://www.hypres.com/ Primary standards involve the exact definition and realization of units of measurement for various quantities, time, length, mass, voltage, resistance, current, etc. International agreements based on the latest scientific knowledge define those units, and their realizations vary depending on the unit itself. For...

Shrink Fitting

Robin A. Rhodes Cryogenic Institute of New England, Inc. rrhodes@nitrofreeze.com Shrink fitting, (or “compression fitting” as it is sometimes called), is a method used to insert a pin or bushing into a housing or other assembly requiring an extremely tight tolerance fit. It can be used as an alternative to...

Telecommunications

From the Winter 2004 issue of Cold Facts magazine The recent M-Calc IV — 4th Industry Assessment workshop discussing military and commercial applications for low-cost cryocoolers, held in November in San Diego, highlighted progress being made in cryogenics as applied in telecommunications. The reliability and long lifetime of projects now...

Power usage: cryogenic systems vs. regular refrigerators

A recent project highlighted to me that closed cycle cryogenic cooling systems use far more electrical power to reduce temperatures by a few watts than regular refrigerators. I am sure it must be something to do with the extra difficulty of removing the heat from the liquid nitrogen or similar...

Redundancy strategies for mechanical -80C freezers

I was wondering what kind of redundancy strategies are people using for their mechanical -80C freezers? I am aware of the following. Please add if you are doing something different. 1) 1 Backup freezer for every 10 freezers – Empty and maintained at -80C at all times 2) Backup C02...

Method to move components in a cryogenic environment

Does anyone know of a method with which to reliably move components in a cryogenic environment? We are interested in moving detectors in a cryogenically cooled (2K) vacuum chamber, which is contained within a larger cryostat/isolation vacuum with thermal shields. As the desired horizontal or vertical displacement is between 10...
