Qubit Measurement Systems Right Out of the Box?

Necessity of mK-Cryogenics-During the past years, advances in both lithography and millikelvin cryogenics have supported and enabled vast improvement in the sophistication of experimental research on electrical circuits that display uniquely quantum mechanical behavior. It comes as no surprise that dilution refrigerator measurement systems have moved beyond basic physics research...

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...

New Green Storage System Offers Renewable Energy On-Demand

Back to the Future movie fans may remember the term “flux capacitor” as a fictional device that allows for time travel. That device still doesn’t exist, but a University of Central Florida storage technology does use a different type of flux capacitor developed by NASA. While trying to find a way...

Commonwealth Fusion Systems Opens Fusion Energy Campus on the Fastest Path to Bring Clean Fusion Energy to the World

Commonwealth Fusion Systems (CFS) officially opened its new campus to support the development and deployment of commercial fusion energy. The ceremonial event included visits from U.S. Secretary of Energy Jennifer M. Granholm, U.S. Senator Elizabeth Warren, U.S. Senator Edward Markey, U.S. Representative Lori Trahan, Massachusetts Lieutenant Governor Kim Driscoll, along...

Oxygen Diffuser Project Underway in Kentucky

The U.S. Army Corps of Engineers Nashville District is executing a sustainability project funded by the Section 212 Program to install an upstream diffuser system at Wolf Creek on the Cumberland River in Jamestown, Kentucky. The district is partnering with power preference customers, the Southeastern Power Administration, and Tennessee Valley...

Liquid Hydrogen

Hydrogen becomes a liquid at 20K and 1 bar. Liquid hydrogen (LH2) is an important substance in industry, transportation and research. Industrial uses of hydrogen include applications in the electronics, glass, chemical and metal processing fields. In these applications, the hydrogen is generally used as a room temperature gas but...

Superconducting Radiofrequency Cavities

Superconducting radio frequency (SRF) cavities represent an important application of cryogenics and superconductivity. SRF cavities are a technology for accelerating charged particle beams via the transfer of radiofrequency (RF) energy to the beams via resonant structures. As such, they are frequently found in large particle accelerators used for scientific research....

Thermal Radiation Shields

Actively cooled thermal radiation shields are a common feature of cryostats whose lowest temperature is less than 77K. These shields, which typically operate at temperatures between that of LN2 and 40K, block thermal radiation from higher temperatures from reaching lower temperature cryogenic components or fluids. Since the heat radiated from...

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...
