Rules of thumb for the design length of transition tubes
Are there any rules of thumb for the design length of transition tubes in order to prevent condensation at the room temperature end? By “transition tube,” I mean some standard size (O.D. and wall thickness) type 304 stainless steel tube with either 4 K or 80 K at one end and room temperature (300 K) … Continue reading Rules of thumb for the design length of transition tubes
Cuprate superconductors defy convention
To engineers, it’s a tale as old as time: Electrical current is carried through materials by flowing electrons. But physicists at the University of Illinois and the University of Pennsylvania found that for copper-containing superconductors, known as cuprates, electrons are not enough to carry the current.

BNSF to test liquefied natural gas in road locomotives
BNSF will begin testing a small number of locomotives using liquefied natural gas (LNG) as an alternative fuel later this year, BNSF chairman and CEO Matthew K. Rose announced at the CERAWeek conference on March 6.
Quantum refrigerator offers extreme cooling and convenience
Researchers at the National Institute of Standards and Technology (NIST) have demonstrated a solid-state refrigerator that uses quantum physics in micro- and nanostructures to cool a much larger object to extremely low temperatures.
Herschel to finish observing soon
ESA’s Herschel space observatory is expected to exhaust its supply of liquid helium coolant in the coming weeks after spending more than three exciting years studying the cool Universe.
Goddard scientists work at extreme edge of cosmic ice
Behind locked doors, in a lab built like a bomb shelter, Perry Gerakines makes something ordinary yet truly alien: ice. This isn't the ice of snowflakes or ice cubes. No, this ice needs such intense cold and low pressure to form that the right conditions rarely, if ever, occur naturally on Earth.
A cyclotron’s long journey home
Seventy-five years after one of the world’s first working cyclotrons was handed to the London Science Museum, it has returned to its birthplace in the Berkeley hills, where the man who invented it, Ernest O. Lawrence, helped launch the field of modern particle physics as well as the national laboratory that would bear his name, Lawrence Berkeley National Laboratory.
Man-made material pushes the bounds of superconductivity
A multi-university team of researchers has artificially engineered a unique multilayer material that could lead to breakthroughs in both superconductivity research and in real-world applications.
ConocoPhillips may halt export from Kenai LNG in Alaska
ConocoPhillips said it may halt LNG shipments from the company’s Kenai facility in Alaska after March 31 when the company’s export license expires, LNG World News reported.
Tributes to Donna Jung, International Cryogenics
It is with great regret that we report the sudden death of Donna Jung, President of International Cryogenics, on February 1, 2013. Jung was a leader in the cryogenic community, president of a longtime CSA Corporate Sustaining Member company, and a stalwart supporter of the Society. Jung, 52, was one of the second generation company leaders who make up the “Cryomafia.” She facilitated gatherings of the Cryomafia and played a key role in keeping the group together.
