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...

Next-Generation Oilless Cryogenic ORC Turbine Generator

Mitsubishi Heavy Industries, Ltd. (MHI) and Mitsubishi Heavy Industries Marine Machinery and Equipment Co., Ltd. (MHI-MME), a wholly owned operating company of MHI based in Nagasaki, have successfully conducted demonstration testing of 100 kW class cryogenic ORC (Organic Rankine Cycle) power generation using the world’s first “next-generation oilless cryogenic turbine...

Students Design Experimental Fuel System To Power Liquid-Propellant Rocket Engines

Aerospace Engineering students Alex Clay and Samir Ahmed have spent the past four years at Embry-Riddle Aeronautical University manufacturing complex liquid-propellant rocket engines. Now, as they near graduation, there is one last thing they’d like to do: Prepare for ignition. Along with fellow members of the university’s Experimental Rocket Propulsion Laboratory...

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...

Regenerators

Regenerators or regenerative heat exchangers are a key component of cryocoolers such as pulse tube cryocoolers (Cold Facts, August 2014). Regenerator performance greatly affects the coefficient of performance of cryocoolers. Improvements in regenerator design and, in particular, regenerator materials have been an important factor in the improvement of the performance...

Pulse Tube Cryocoolers

The development of pulse tube cryocoolers has been a significant topic of research and development over the past 20 or so years. Pulse tube cryocoolers have a number of advantages over other types of cryocoolers and are now available commercially. In order to understand pulse tube cryocoolers, it’s best to...

Thermal Expansion

Thermal expansion refers to the change in size (length or volume) that a material undergoes as its temperature changes. In cryogenic systems this effect can be quite large and must be allowed for in the design. In isotropic materials, which include most engineering materials, the thermal expansion is the same...

Magnets

From “Superconductivity: Present and Future Applications” by the Coalition for the Commercial Application of Superconductors. Particle physics uses accelerators to recreate the conditions of the early universe in an attempt to piece together the complex puzzle of how we got to where we are today. These huge machines are used...

Energy Storage

From “Superconductivity: Present and Future Applications” by the Coalition for the Commercial Application of Superconductors. With power lines increasingly congested and prone to instability, strategic injection of brief bursts of real power can play a crucial role in maintaining grid reliability. Small-scale Superconducting Magnetic Energy Storage (SMES) systems, based on...

Astronomy

ASTRONOMY IN SPACE by Peter V. Mason, retired, Jet Propulsion Laboratory, and Visiting Associate, California Institute of Technology. Pmason@alumni.caltech.edu In thinking about the reasons to perform astronomy in space, we first consider the effect of the earth’s atmosphere. On a scale of decreasing energy, gamma rays, cosmic rays, X-rays and...

Cryocoolers

What is a Cryocooler? A mechanism that can extract heat from an object (cooler) and by doing so draw its temperature down below approximately 150 Kelvin (cryo). — (Courtesy Dr. Willy Gully) What is the difference between a Cryocooler and a Cryostat? A cryostat is any device designed to maintain...

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?
