MagLab Awarded DOE Grant to Develop New SRF Cavities

The National High Magnetic Field Laboratory (MagLab, CSA CSM) is playing a role in a nationwide effort to make human-scale particle accelerators for a host of applications. And now, with a $1 million grant from the US Department of Energy, scientists at the lab's Applied Superconductivity Center (ASC) are developing...

Advancing Tissue Engineering with 3-D Cryoprinting

The importance of additive manufacturing (AM) and 3-D printing has increased in almost every field of engineering, including biomedical engineering, a field where researchers are advancing applications such as 3-D cryoprinting. The technology is poised to develop into an important step in tissue engineering as it can produce biological tissues...

NASA Awards Funding to Support Professional Development Programs for STEM Educators

NASA’s Glenn Research Center in Cleveland has awarded approximately $125,000 to schools and organizations to launch professional development programs for science, technology, engineering and math (STEM) educators. The award is intended to strengthen STEM programs for K-12 teachers across Ohio through the use of NASA content. The grant also includes...

Quantum Data Takes a Ride on Sound Waves

Yale scientists have created a device that uses sound waves to store quantum information and convert it from one form to another, all inside a single integrated chip. The device allows a superconducting artificial atom, or qubit, to exchange energy and quantum information with a high-frequency bulk acoustic wave resonator....

FCC and the Superconducting Magnets of the Future

Physicists at CERN are counting on new magnets, ones capable of generating fields of 16 Tesla or more, to increase the energy of its future circular colliders. To achieve these levels, researchers working on CERN's Future Circular Collider (FCC) study have developed a test station known as FRESCA2, a dipole...

Injecting New Life into the LHC

CERN launched the LHC Injectors Upgrade (LIU) project in 2010 to prepare its accelerator complex for the immense challenges of the HL-LHC. Now, in a report appearing in CERN Courier, engineers from the project have provided a status update. In addition to enabling the necessary proton and ion injector chains...

Adiabatic Demagnetization Refrigeration

Reaching temperatures below 1K requires different techniques than the various helium gas cycles found in large scale refrigeration plants and small cryocoolers. One of these techniques is Adiabatic Demagnetization Refrigeration (ADR). This technique takes advantage of the fact that the entropy of paramagnetic materials in a magnetic field is lower than...

Cryogen-Free

A cryogen is any fluid that operates at cryogenic temperatures (below roughly 150K – 120K). Using this definition, helium gas at 40K is a cryogen. Another more restrictive definition is to use cryogen to refer specifically to liquids at cryogenic temperatures. This is generally how it is used in the...

Cryostats and Cryocoolers

A cryostat is any device designed to maintain things (including fluids) at cryogenic temperatures. In general usage, cryostats tend to be passive devices rather than providing active cooling. In this usage, cryostats keep things cold by thermally isolating them from room temperature. This generally is accomplished by a combination of...

Food Processing

Cryogenics and Food The industrial gas industry provides a host of products and services related to food. The various gases have useful and sometimes fascinating applications in food industry. “The food industry is not a homogenous industry. The needs of customers processing hamburger vs. poultry vs. strawberries vs. seafood, for...

Primary Standards

Elie K. Track Hypres, Inc. elie@hypres.com http://www.hypres.com/ Primary standards involve the exact definition and realization of units of measurement for various quantities, time, length, mass, voltage, resistance, current, etc. International agreements based on the latest scientific knowledge define those units, and their realizations vary depending on the unit itself. For...

Shrink Fitting

Robin A. Rhodes Cryogenic Institute of New England, Inc. rrhodes@nitrofreeze.com Shrink fitting, (or “compression fitting” as it is sometimes called), is a method used to insert a pin or bushing into a housing or other assembly requiring an extremely tight tolerance fit. It can be used as an alternative to...

Telecommunications

From the Winter 2004 issue of Cold Facts magazine The recent M-Calc IV — 4th Industry Assessment workshop discussing military and commercial applications for low-cost cryocoolers, held in November in San Diego, highlighted progress being made in cryogenics as applied in telecommunications. The reliability and long lifetime of projects now...

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?
