2nd International Conference on Cryogenics and Refrigeration Technologies

The city of Bucharest hosted the 2nd International Congress on Cryogenics and Refrigeration Technologies May 7-10, welcoming attendees with delicious food, pleasant parks, numerous museums and plenty of research and conversation.

Columbia Researchers Squeeze Light into Nanoscale Devices and Circuits

Columbia investigators have invented of a novel "home-built" cryogenic near-field optical microscope that has enabled them to directly image, for the first time, the propagation and dynamics of graphene plasmons at variable temperatures down to -250°C.

OPERA Presents Its Final Results on Neutrino Oscillations

In a paper published in the journal Physical Review Letters, the OPERA collaboration reports the observation of a total of 10 muon to tau-neutrino conversion events, demonstrating unambiguously that muon neutrinos oscillate into tau neutrinos on their way from CERN, where muon neutrinos were produced, to OPERA at the Gran...

NASA’s Cold Atom Lab Launches, Coldest Spot in Universe Now on ISS

NASA's Cold Atom Lab (CAL) facility was included in the cargo that launched to the International Space Station on the Orbital ATK CRS-9 mission. CAL produces clouds of atoms that are ten billion times colder than deep space, using lasers and magnetic forces to freeze the atoms until they are...

Canadian Researchers Working on Novel MRI for ISS

The Canadian Space Agency has awarded a research team at the University of Saskatchewan a contract to design and engineer an ankle-sized MRI device for the International Space Station. The device, according to the team, will ultimately monitor the bone health of astronauts during prolonged space trips, where weightless conditions...

Jlab Research Shows Protons under More Pressure Than Neutron Stars

Scientists at the Thomas Jefferson National Accelerator Facility (CSA CSM) recorded the first measurement of pressure distribution inside a proton and reported in journal Nature that inside every proton in every atom in the universe is a pressure cooker environment that surpasses the atom-crushing heart of a neutron star.

Liquid Hydrogen

Hydrogen becomes a liquid at 20K and 1 bar. Liquid hydrogen (LH2) is an important substance in industry, transportation and research. Industrial uses of hydrogen include applications in the electronics, glass, chemical and metal processing fields. In these applications, the hydrogen is generally used as a room temperature gas but...

Superconducting Radiofrequency Cavities

Superconducting radio frequency (SRF) cavities represent an important application of cryogenics and superconductivity. SRF cavities are a technology for accelerating charged particle beams via the transfer of radiofrequency (RF) energy to the beams via resonant structures. As such, they are frequently found in large particle accelerators used for scientific research....

Thermal Radiation Shields

Actively cooled thermal radiation shields are a common feature of cryostats whose lowest temperature is less than 77K. These shields, which typically operate at temperatures between that of LN2 and 40K, block thermal radiation from higher temperatures from reaching lower temperature cryogenic components or fluids. Since the heat radiated from...

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?
