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.

Transfer Lines

Transfer lines may in some real sense be thought of as the cryogenic fluid analogy of current leads. While current leads carry electrical power to where it’s required in a cryogenic system, transfer lines do the same with cryogenic fluids. Transfer lines range in complexity from very simple U-tubes containing...

Zero Boiloff

Zero Boil Off cryostats are those that contain liquid cryogens but are designed to eliminate or vastly reduce the boil off of  the liquid. These cryostats combine some of the advantages of Cryogen-Free systems (e.g. ease of use and long operational lifetime) with the advantages associated with a reservoir of liquid...

Cryomodule

Cryomodule is a term that is most commonly used to refer to cryostats that contain superconducting radio frequency (SRF) cavities. Such cavities are used to accelerate charged particle beams and are a major component of modern particle accelerators. Using the term cryomodule to refer to cryostats containing SRF cavities appears...

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...
