Shine on: Upgraded Advanced Photon Source sees first X-ray light for science

A new era of science at the Advanced Photon Source (APS) is ready to begin. On June 17, 2024, the facility at the U.S. Department of Energy’s (DOE) Argonne National Laboratory delivered its first X-ray light beams to a scientific beamline as part of a comprehensive and complex upgrade. The...

Space Systems Command Grants Contracts for Space Laser Communication Prototypes

The EST program, part of SSC’s Space Domain Awareness and Combat Power Program Executive Office, aims to create on-orbit crosslink compatibility among future space systems. This will be achieved through a standardized enterprise waveform implemented in a long-range space optical communications terminal that is low in size, weight, power, and...

100 Years of Quantum Is Just the Beginning

Recognizing the importance of quantum science and the need for wider awareness of its past and future impact, dozens of national scientific societies gathered together to support marking 100 years of quantum mechanics with a U.N.-declared international year. The timeline of endorsements for this international year also included the International Union of Pure and...

Cool It Down–Isochoric Preservation

If you’ve ever made the mistake of putting certain fresh fruits or vegetables in the freezer, then you’re already familiar with the effects of freezing on biological tissue. Banana skins turn black and slimy. Whole oranges leak and deflate. Lettuce comes out limp and soggy. The cause of all this...

Advancing Spin Qubit Technology With Cryogenic Probing

In a recent article published in Nature, researchers developed a 300-mm cryogenic probing process to obtain high-volume data on spin qubit devices across full wafers. They optimized an industry-compatible process to fabricate spin qubit devices on a low-disorder host material, enabling automated probing of single electrons in spin qubit arrays across...

HL-LHC’s Cold Powering System Successfully Passed Tests

If you’re an avid follower of High-Luminosity LHC (HL-LHC) news, you will no doubt already have heard about “the python”, the new superconducting link developed at CERN. It is a component of the new cold powering system that will power the HL-LHC inner triplet magnets, which will focus proton beams more...

Helium II

Helium II (He II) refers to the second liquid phase of the most abundant helium isotope (4He). Helium II is also referred to as superfluid helium. Helium II occurs once the temperature of the liquid helium drops below 2.17K. The phase transition between the first liquid phase of Helium (referred...

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...

Separated layers of ice over a pipe

I want to know that why there are different layers of ice over a pipe carrying a cryogenic fluid, each layer separated with clear marks / lines? What do these layers signify?
