Cryogenic Engineers, Researchers Gather for CEC/ICMC 2019

Scientists and engineers gathered in Hartford CT for the 2019 CEC/ICMC conference. Held in the Connecticut Convention Center, with plenary sessions in the adjoining Marriot Hotel, CEC/ICMC hosted cryogenic experts and industry leaders sharing information and ideas from July 21-25. The traditional oral and poster sessions were held throughout the...

Maglab Creates World Record Magnetic Field with Mini Magnet, Moves to Perfect Findings

The National High Magnetic Field Laboratory (CSA CSM) at FSU in Tallahassee FL recently introduced a novel magnet half the size of a spent toilet tissue roll that usurped the title of “world’s strongest magnetic field” from the metal titan that had held it for two decades. MagLab scientists and...

Experimental Mini-Accelerator Achieves New World Energy Record

Scientists at DESY in Hamburg have achieved a new world record for an experimental type of miniature particle accelerator. For the first time, a terahertz-powered accelerator has more than doubled the energy of the injected electrons. At the same time, the setup significantly improved the electron beam quality compared to...

World’s Smallest MRI Reveals Magnetic Field of Single Atoms

Researchers at the Center for Quantum Nanoscience within the Institute for Basic Science at Ewha Woman’s University in Korea recently made a major scientific breakthrough by performing the world’s smallest magnetic resonance imaging. In an international collaboration with colleagues from the US, QNS scientists used their new technique to visualize...

Helium Shortage Leads World to Reconsider Applications, Procedures for Efficient Use

The global market is facing its third shortage of helium. Beginning in the spring of 2018, a series of planned and unplanned outages affected global access to supply. While many may immediately think this means party balloons are at the greatest risk, those who know and use helium—scientists, researchers, doctors,...

Cryotreating Strengthens Anti-Embolism Stockings for Cancer Patients

Anti-embolism stockings are designed to promote healthy blood flow and prevent blood clotting. The cost can range from $50 to $200 and they wear out quickly, leading to more expense. To ease the financial burden on cancer patients, Circle City Cryogenics in Indianapolis has developed a cryotreating process that improves...

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...

Cryogenic Treatment of Materials

F.J. Diekman Controlled Thermal Processing, Inc. info@metal-wear.com Cryogenic Processing (also called cryogenic treatment, and incorrectly “cryogenic tempering”) is a process that uses cryogenic temperatures to modify materials to enhance their performance. Cryogenic Processing involves the slow reduction in temperature of the material to at least -300°F (-185°C) and holding the...

Cryogenics in Space

Peter Kittel University of California-Berkeley pkittel@cal.berkeley.edu Space Cryogenics is the application of cryogenics to space missions. These applications fall into two broad areas, supporting space science missions and supporting the space transportation infrastructure. Science applications: The atmosphere is opaque to much of the electro-magnetic spectrum. In space, the absence of...

Need help comparing chest freezers and upright freezers

Currently we use in our Biobank an upright -80 freezer to store all our samples. We are planning to buy a fully automated bio-repository storage that will do the picking of samples under restricted conditions. But in the meantime I foresee that we have to pick the samples manually. The...

Need recommendations for cryogenic vials

I am looking into standardizing our range of bio storage tubes (cryogenic vials). These will be for both blood and tissue samples and their derivatives. Any recommendations, comments on Micronics, Nalgene, Nunc and or others that are suitable for long term -80 C and -196 C storage, DNA/RNA suitable, would...

We need a custom machine for flash freezing of water

We are an ice making company and have started a new project, which is related to flash freezing of water. It is based on cryogenics technology and we need a custom made machine. I would kindly ask you to pass me a few companies who would be interested in such...

Looking for a pump suitable for cold liquids

I would like to construct a small cooling circuit (appr. 50 x 50 cm) pumping liquid at a temperature down to -120°C from a cold reservoir to the specimen to be cooled. The tubes and connections are not a problem, but does somebody know a pump (suction/compression for circulation) suitable...
