SESAME Delivers Its First Light

Scientists at SESAME (Synchrotron-light for Experimental Science and Applications in the Middle East) recorded first monochromatic light through the XAFS/XRF spectroscopy beamline in November, signaling the start of the laboratory’s experimental program. The beamline, SESAME’s first to come on stream, delivers X-ray light that will be used to carry out...

FAST Electron Beam Achieves Milestone Energy

In November, a team at the Fermilab Accelerator Science and Technology (FAST) facility ramped up a beam of electrons to 300 million electronvolts, a double milestone event, according to the lab. For one, the beam surpassed the threshold needed to launch a new accelerator physics program at Fermi National Accelerator...

Argonne Welcomes GRETINA Back Home

A world-class gamma ray spectrometer called GRETINA has returned to Argonne National Laboratory (CSA CSM) for a second run expected to last 18 months. Scientists will use the instrument in conjunction with Argonne’s Fragment Mass Analyzer, where it will enable studies of nuclei at or near the proton drip line...

UTSW Releases First Atomic Structure From its Cryo-EM Facility

UT Southwestern Medical Center researchers have published a 3-D atomic structure of the ion channel found in mammals that is implicated in a rare, inherited neurodegenerative disease in humans. The work marks the first such structure determined using the university’s $17 million cryo-electron microscopy (cryo-EM) facility.

Novel Lenses Enable X-ray Microscopy with Record Resolution

Researchers at DESY have reported the creation of novel lenses that enable X-ray microscopy with record resolution. The new lenses consist of over 10,000 alternating layers of a new material combination—tungsten carbide and silicon carbide—that allowed the team to achieve a focus spot size with a diameter of less than...

ICC20 Accepting Abstracts for 2018 Conference

Abstract submission is now open for the 20th International Cryocooler Conference (ICC20), the premier global gathering on cryocooler technology. The meeting will feature oral and poster presentation sessions, plus CSA's Foundations of Cryocoolers short course.

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...

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...

An Issue of Pressure and Flow Rate in a Supply Tank

Please help solve this problem: A supply tank requires a vaporizer to generate sufficient pressure to pump stored fluid up into a vehicle or tank. The available head is limited as the tank level falls and it is important to minimize the system pressure drop to maintain the desired flow...

Using MLI on VJ Line Joints or Cryo Storage Tanks

When installing Multi Layer Insulation (MLI) blankets on VJ line joints or cryo storage tanks should they be wrapped and tied down tight or loose? These are usually pre-cut to size. Also should they have an access hole at the point of where the molecular sieve is installed to help...
