UT-ORNL team makes first particle accelerator beam measurement in six dimensions

The first full characterization measurement of an accelerator beam in six dimensions is expected to advance the understanding and performance of current and planned accelerators around the world.

One cool camera: LSST’s cryostat assembly completed

The LSST cryostat, now fully assembled, will keep the camera’s image sensors continuously cooled to -150°F for crisp, high-sensitivity views of the night skies.

Space Station Experiment Reaches Ultracold Milestone

The International Space Station is officially home to the coolest experiment in space, after the installation of NASA’s Cold Atom Laboratory which is producing Bose-Einstein condensates

DOE Approval Moves PIP-II Accelerator Upgrade To Perform Baseline Stage at Fermilab

The US Department of Energy formally approved Fermi National Accelerator Laboratory (CSA-CSM) to proceed with its design of PIP-II, an accelerator upgrade project that will provide increased beam power to generate an unprecedented stream of neutrinos—subatomic particles that could unlock our understanding of the universe—and enable a broad program of...

In Memoriam: Dr. Roger W. Boom

It is with great regret that we report the death of Dr. Roger W. Boom, emeritus professor from the University of Wisconsin and mentor and inspiration to a great many leaders in the fields of cryogenic engineering and superconductivity. Dr. Boom’s career spanned more than thirty years during which he...

New Study Calls for US-based Electron Ion Collider

A new report, sponsored by the DOE and undertaken by the National Academies of Sciences, Engineering and Medicine, argues that a domestic electron ion collider could unlock the scientific mysteries of atomic nuclei and maintain US leadership in accelerator science.

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?
