Cryogenic CMOS Innovations Advance Quantum Computing

In the race to unlock the full potential of quantum computing, recent breakthroughs in cryogenic CMOS technology are paving the way for a new era of computational power. At the forefront of this frontier are pioneering efforts by Semiwise and SureCore, in collaboration with Cadence Design Systems, aimed at overcoming...

NASA Completes Flight Readiness Review for GOES-U Mission

NASA, NOAA (National Oceanic and Atmospheric Administration), SpaceX, and GOES-U (Geostationary Operational Environmental Satellite-U) mission managers met on June 20 to conduct a Flight Readiness Review at NASA’S Kennedy Space Center in Florida. During the review, teams provided an update on the mission status and certified the readiness to proceed with...

Shine on: Upgraded Advanced Photon Source sees first X-ray light for science

A new era of science at the Advanced Photon Source (APS) is ready to begin. On June 17, 2024, the facility at the U.S. Department of Energy’s (DOE) Argonne National Laboratory delivered its first X-ray light beams to a scientific beamline as part of a comprehensive and complex upgrade. The...

Space Systems Command Grants Contracts for Space Laser Communication Prototypes

The EST program, part of SSC’s Space Domain Awareness and Combat Power Program Executive Office, aims to create on-orbit crosslink compatibility among future space systems. This will be achieved through a standardized enterprise waveform implemented in a long-range space optical communications terminal that is low in size, weight, power, and...

100 Years of Quantum Is Just the Beginning

Recognizing the importance of quantum science and the need for wider awareness of its past and future impact, dozens of national scientific societies gathered together to support marking 100 years of quantum mechanics with a U.N.-declared international year. The timeline of endorsements for this international year also included the International Union of Pure and...

Cool It Down–Isochoric Preservation

If you’ve ever made the mistake of putting certain fresh fruits or vegetables in the freezer, then you’re already familiar with the effects of freezing on biological tissue. Banana skins turn black and slimy. Whole oranges leak and deflate. Lettuce comes out limp and soggy. The cause of all this...

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...

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...

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?
