ICHEP Publishes 2016 Proceedings

Professor Young-Kee Kim, chair of ICHEP 2016 and professor of physics at the University of Chicago, has announced that proceedings from the high energy physics conference have been published online. The proceedings are organized by session topic and include full PDFs from presenters and research teams.

Microsoft and Rambus Extend Cryogenic Memory Collaboration

Microsoft and Rambus Inc. have expanded a research collaboration begun in 2015 to develop prototype systems that optimize computer memory performance at cryogenic temperatures. The new agreement extends joint efforts to enhance memory capabilities, reduce energy consumption and improve overall system performance.

GOES-S Undergoes Thermal Vacuum Testing

In March, engineers at Lockheed Martin Space Systems lifted NOAA's Geostationary Operational Environmental Satellite-S (GOES-S) into a thermal vacuum chamber to begin testing its ability to function in the cold void of space at its orbit 22,300 miles above the Earth. To simulate the environment of space, researchers removed air...

Hybrid Airships to Transfer Helium from Tanzania

Helium One, a company that holds a prospecting license for recently discovered helium deposits in Tanzania, intends to use Lockheed Martin's LMH-1 hybrid airships to transport the gas out of the country. The company's license includes three project areas in Tanzania, encompassing more than 4,500 km² of land with helium...

Air Products Expands Operations in South China

Air Products has opened a cryogenic air separation plant in the Guangdong Province of South China. The facility will produce both gaseous oxygen and nitrogen in a modular space that allows for easier field installation and requires less land, according to the company.

LArIAT Upgrade Tests DUNE Design

Scientists from the LArIAT experiment at Fermi National Accelerator Laboratory have begun a proof-of-concept test for the planned Deep Underground Neutrino Experiment (DUNE). The researchers studying what will happen if the space between detection wires inside the future DUNE detectors is increased from three millimeters to five, a design that...

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?
