GENH2 Partners with H2 Genesis to Provide Small-Scale Hydrogen Liquefaction

GenH2, an industry leader in hydrogen infrastructure solutions, announced that the company has signed a partnership agreement with H2 Genesis, a leading liquid hydrogen infrastructure and operations company, to deliver liquid hydrogen across North America. In their first collaboration, GenH2, as manufacturer, and H2 Genesis, as owner-operator, will deploy the...

First Measurements of Hydrogen-Boron Fusion in a Magnetically Confined Fusion Plasma

As fusion developers around the world race to commercialize fusion energy, TAE Technologies has pioneered the pursuit of the cleanest and most economical path to providing electricity with hydrogen-boron (also known as p-B11 or p11B), an abundant, environmentally sound fuel. Recently, the company announced, in collaboration with Japan’s National Institute...

The Development of an AMRR for Sub-Kelvin Cooling of Space Science Instrumentation – ICC21 Best Student Paper Award Recipient

Introduction-Cryogenic detectors have higher sensitivity and better energy resolution than alternative sensors, making them an attractive option for space exploration and essential for observing low energy photons in the near- or far-IR, X-ray and submillimeter ranges.[1] Since NASA’s first cryogenic missions in the early 1980s, increasingly complex space detectors have...

Back to the Future: Combining Hydrogen Hybrid Technology and Enhancing Solar & Wind

The first time I saw the first prototype of the Dylan Energy system, I thought of old Doc Brown and Back to the Future. Remember them? Doc invented something called the ‘Flux Capacitor.ʼ With the Dylan Energy system and our partners, we are capable of consuming 400 tons daily of municipal...

The Next Generation in Cryogenics and Superconductivity

CSA’s annual Young Professionals introduces outstanding engineers, scientists, and technicians (under 40) who are making fascinating contributions to the cryogenics and superconductivity industries. Debuted in the summer of 2006, this spotlight shines on future leaders who show the promise of making a difference in their fields. We are proud to...

Chase Coolers and Their Long History in CMB Science

Making advances in science requires the proper tools. Often those tools must be developed by scientists themselves. That’s the story of most science missions studying Cosmic Microwave Background radiation (CMB). Sub-Kelvin coolers developed by Chase Research Cryogenics (CSA CSM) have played a strategic role in many of these missions. Let’s...

Transfer Lines

Transfer lines may in some real sense be thought of as the cryogenic fluid analogy of current leads. While current leads carry electrical power to where it’s required in a cryogenic system, transfer lines do the same with cryogenic fluids. Transfer lines range in complexity from very simple U-tubes containing...

Zero Boiloff

Zero Boil Off cryostats are those that contain liquid cryogens but are designed to eliminate or vastly reduce the boil off of the liquid. These cryostats combine some of the advantages of Cryogen-Free systems (e.g. ease of use and long operational lifetime) with the advantages associated with a reservoir of liquid...

Cryomodule

Cryomodule is a term that is most commonly used to refer to cryostats that contain superconducting radio frequency (SRF) cavities. Such cavities are used to accelerate charged particle beams and are a major component of modern particle accelerators. Using the term cryomodule to refer to cryostats containing SRF cavities appears...

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...

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?
