Physicists Develop Faster Method to Create Bose-Einstein Condensates
MIT physicists have improved the cooling techniques used to cool atoms into Bose-Einstein condensates. The new method is faster than the conventional one and conserves a large fraction of the original atoms.
A New, Cold Window into Electron Behavior
Physicists at MIT and Princeton University have developed a technique that can peer deep beneath the surface of a material to identify the energies and momenta of electrons there.
Linde Lifts Macy’s Thanksgiving Day Parade Balloons High
The iconic Macy’s Thanksgiving Day Parade balloons once again soared above the streets of New York City thanks to helium supplied by Linde North America, Inc. Linde supplied some 300,000 cubic feet of helium to the parade this year, the 23rd consecutive year of its partnership with Macy’s.
Physicists Propose Superfluid Helium Dark Matter Detector
Physicists from Brown University have devised a new strategy for directly detecting dark matter with a tub of superfluid helium. The idea is that dark matter particles passing through the tub should, on very rare occasions, smack into the nucleus of a helium atom.
NMR Imaging Reveals How Flu Virus Spreads from Cell to Cell
After a flu virus infects a host cell and hijacks its inner workings to create copies of itself, these copies gather into viral buds that break free from the host cell to infect again. A new study from MIT now provides the clearest picture yet of how the buds are pinched off from the host cell membrane.
JWST Completes Final Cryogenic Testing
NASA engineers unsealed the vault-like, 40-foot diameter, 40-ton door of Chamber A at Johnson Space Center in Houston on November 18, signaling the end of nearly 100 days of cryogenic testing for the agency's James Webb Space Telescope.
Cable-in-Conduit Conductors
Cable-in-Conduit Conductors (CICC) are a common form of superconducting cable used in large-scale applications. There are several varieties of CICCs, but they all consist of many small, stabilized superconducting wires contained within a conduit through which a coolant (typically supercritical He II) flows. Figure 1 shows the cross section of a number of different CICCs.CICCs … Continue reading Cable-in-Conduit Conductors
Cryogenic Aspects of Future NASA Mars Exploration
Cryogenic fluids are the basis for many different in-space systems, and several recent publications from NASA examine potential roles for cryogenic fluids in human missions to the red planet. Propulsion, in-situ resource utilization and power storage and generation represent the main systems using cryogenics.
Design and Application of Cryogenic Valves
Cryogenic media enhance our daily lives in many ways, from flash-frozen food to aerospace, cryosurgery and even special effects. Durability, dependability and long life are expected in all such applications, so manufacturers of cryogenic instruments should use the best construction methods available to handle the demanding requirements of controlling cryogenic media under pressure.
