Understanding the Origin of Matter with the CUORE Experiment

The Cryogenic Underground Observatory for Rare Events (CUORE) can search for these rare NLDBD processes using different nuclei. Scientists rely on complementarity among searches using different nuclei to have a better understanding of the underlying physics in the process. Complementarity in physics involves theories that contrast with each other but...

How the SpaceX Explosion Would Have Been Different in Florida

Shortly after SpaceX’s massive Starship launched from Texas on its first full test early Thursday, the 400-foot stack of hardware began to tumble until it broke apart in a fiery explosion over the Gulf of Mexico. The overall demonstration mission – a test of the new rocket’s ability to ignite and clear the pad’s 500-foot tower...

Svanehøj Acquires Complete Cryogenic Services

With its third company acquisition in just over two years, marine pump specialist, Svanehøj, continues to expand its service solution business, this time by taking over California-based Complete Cryogenic Services (CCS), a specialist in service and overhaul of submerged pumps on LNG tankers. The number of LNG tankers globally has grown...

Skyroot Aerospace and Dhawan-II’s More Powerful 3D-Printed Cryogenic Engine

In 2020, the world was introduced to Dhawan-I, a 3D printed cryogenic engine made by Skyroot Aerospace. Three years later, the Indian company has been working on a more powerful model, unveiling to the public the new and improved Dhawan-II, which is said to have successfully completed testing. Like its predecessor,...

A Game Changer for CERN

CERN’s new visitor and education center, Science Gateway, due to open this autumn, will welcome up to half a million people each year. Project leader Patrick Geeraert describes how this iconic project came about, how it will operate, and what it aims to achieve. How did the idea for Science...

New SLAC-Stanford Battery Center Targets Energy Transition

The Department of Energy’s SLAC National Accelerator Laboratory and Stanford University announced the launch of a new joint battery center at SLAC. It will bring together the resources and expertise of the national lab, the university and Silicon Valley to accelerate the deployment of batteries and other energy storage solutions...

Space Cryogenics

Space cryogenics is, somewhat obviously, the application of cryogenics to space exploration and science. The use of cryogenics in space optimizes the launching of vehicles, provides power and life support to spacecraft and is critical for many scientific observations.Space cryogenics has a number of challenges and has driven both pure...

Exergy

The science of thermodynamics plays a major role in cryogenics. It underlies the various refrigeration cycles, from Carnot to Brayton (Cold Facts Vol. 32 No. 2) and Joule-Thomson, is a fundamental part of the definition of terms such as coefficient of performance (Cold Facts Vol. 31 No. 1) and even...

Cryogenic Treatment

Cryogenic treatment is the process of cooling materials to cryogenic temperatures temporarily to improve their material properties at room temperature. This is distinct from cooling materials down to cryogenic temperatures to take advantage of phenomena such as superconductivity that only occur at cryogenic temperatures. Cryogenic treatment, sometimes also referred to...

Magnetic Levitation

From http://www.superconductors.org. Magnetic-levitation is an application where superconductors perform extremely well. Transport vehicles such as trains can be made to “float” on strong superconducting magnets, virtually eliminating friction between the train and its tracks. Not only would conventional electromagnets waste much of the electrical energy as heat, they would have...

Superconductivity

From Superpower website. History of Superconductivity Superconductivity was discovered in 1911 by the Dutch physicist, Heike Kammerlingh Onnes when he was able to liquefy helium by cooling it to 4 Kelvin, or -452°F. This enabled him to cool other materials close to absolute zero and investigate their electrical properties. He...

Medical Applications of Cryogenics

Neutron Therapy Cryogenics is at the heart of nuclear accelerators. Accelerators such as Fermilab’s Tevatron make neutron therapy for cancer possible. From Fermilab Today 4/20/09: Fermilab currently offers neutron therapy. But staff at Fermilab designed and built the proton accelerator used by the nation’s first hospital-based treatment center to use...

Nuclear Physics

Al Zeller National Superconducting Cyclotron Lab (NSCL) at Michigan State University zeller@nscl.msu.edu Cryogenics has a long history in nuclear physics. The technology has its origins in the use of cold traps for maintaining a vacuum, which is required to prevent beam loss and for generating high voltages used in acceleration....

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...
