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...

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...

Helium II

Helium II (He II) refers to the second liquid phase of the most abundant helium isotope (4He). Helium II is also referred to as superfluid helium. Helium II occurs once the temperature of the liquid helium drops below 2.17K. The phase transition between the first liquid phase of Helium (referred...

Cryogenics in Space

Peter Kittel University of California-Berkeley pkittel@cal.berkeley.edu Space Cryogenics is the application of cryogenics to space missions. These applications fall into two broad areas, supporting space science missions and supporting the space transportation infrastructure. Science applications: The atmosphere is opaque to much of the electro-magnetic spectrum. In space, the absence of...

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...
