Toyota Gazoo Racing has unveiled the liquid hydrogen-fuelled GR LH2 Racing Concept car, designed to drive the development of hydrogen technology in motorsport. The ACO H₂ Hydrogen Village was the setting chosen by Toyota Gazoo Racing to premiere the GR LH2 Racing Concept. In keeping with its principle of offering...

Stanford Finds Crystal That Could Revolutionize Quantum Tech

Superconductivity and quantum computing have rapidly evolved from theoretical frontiers to real-world technologies. The 2025 Nobel Prize in Physics recognized breakthroughs in superconducting quantum circuits that promise ultra-powerful computing systems. Yet these technologies demand cryogenic operating conditions, near absolute zero, where most materials lose their useful properties. Identifying materials that...

VALCOR ENGINEERING ADDS NEW VIBRATION LABORATORY

Valcor Engineering Corporation, a longtime designer and manufacturer of precision fluid and motion control components—including cryogenic solenoid valves—has expanded its in-house testing resources with the addition of a new Vibration Laboratory at its Springfield, New Jersey headquarters. The new facility provides full 3-axis (X, Y, Z) vibration testing, including sine...

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...

Cryogenic Electronics

Randall Kirschman, consulting physicist, Mountain View, California ExtElect@gmail.com Cryogenic electronics—the operation of electronic devices, circuits, and systems at cryogenic temperatures—has been a valuable technology for decades. Cryogenic electronics (also referred to as low-temperature electronics, or cold electronics) can be based on semiconductive devices, on superconductive devices, or on a combination...

Particle Physics: High Energy Physics

Cryogenics and High-Energy Physics 1. From symmetry magazine: http://www.symmetrymagazine.org/cms/?pid=1000627: Cryogenics is the study of how materials behave at temperatures near absolute zero. In high-energy particle accelerators, such frigid temperatures reduce the electrical resistance of wires in superconducting magnets, increasing the magnet strength and allowing faster particle acceleration. The same holds...

HTS Degaussing Systems

From the Spring 2009 issue of Cold Facts (Volume 25, Number 2): Thanks to a joint project by the US Navy and a number of industry partners, high temperature superconducting (HTS) technology is now at the heart of an advanced degaussing system aboard the USS Higgins at the naval station...

Magnetic Resonance Imaging

From http://www.superconductors.org: An area where superconductors can perform a life-saving function is in the field of biomagnetism. Doctors need a non-invasive means of determining what’s going on inside the human body. By impinging a strong superconductor-derived magnetic field into the body, hydrogen atoms that exist in the body’s water and...

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...
