Infertile Cancer Survivor Gives Birth Using Frozen, Lab-Matured Egg in Scientific ‘Breakthrough’

In a world first, a French woman has given birth after freezing, thawing and fertilizing her immature eggs in a procedure called in vitro maturation, according to a study published in the journal Annals of Oncology. Doctors say this development "is particularly important for cancer patients, but it’s also a...

Quantum Design and Sumitomo Cryogenics of America Announce Collaboration with Helium Compressor

Developed jointly by Quantum Design and SHI Cryogenics (CSA CSMs), the new R-98 double inverter-driven helium compressor, the first in SHI’s new Revolution™ Series, is compatible with a range of their Gifford-McMahon and Pulse Tube two-stage cryocoolers. It represents the latest in “energy smart” helium compressors that reduce the operating...

Grand Opening Soon: ITER’s Cryostat Base

The first cryostat is being installed at the ITER Tokamak pit for the French fusion project at Saint-Paul-les-Durance. The cryostat base, part of the insulating vessel that encases the ITER Tokamak, is the heaviest of all the machine's components. As the first of four cryostat sections to be lowered into...

Closely Spaced Hydrogen Atoms Could Facilitate Superconductivity in Ambient Conditions

An international team of researchers at the Department of Energy’s Oak Ridge National Laboratory (CSA CSM) has discovered the hydrogen atoms in a metal hydride material are much more tightly spaced than had been predicted for decades—a feature that could possibly facilitate superconductivity at or near room temperature and pressure....

New Coronavirus Protein Identified by Team Including Argonne National Laboratory May Lead to Drug Target

A potential drug target has been identified in a newly mapped protein of SARS-CoV-2, the virus that causes coronavirus disease 2019 (COVID-19). The structure was solved by a team including the University of Chicago, the US Department of Energy’s Argonne National Laboratory (CSA CSM), Northwestern University Feinberg School of Medicine...

The Hyper-Kamiokande Project Is Officially Approved

Hyper-K, a world-leading international scientific research project hosted by Japan, aims to elucidate the origin of matter and the Grand Unified Theory of elementary particles. The project consists of the Hyper-K detector, which has an 8.4 times larger fiducial mass than its predecessor, Super-Kamiokande, and will be equipped with newly...

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...

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...

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...

Looking for some advice regarding cryogenic modeling in ANSYS FEA software

I am looking for some advice regarding cryogenic modeling in ANSYS FEA software. I have been trying to use the Transient Thermal module, in workbench 14.5, to model the cooling of a device in a dilution fridge. I have approximate values for the cooling power of each plate in the...
