MagLab Awarded DOE Grant to Develop New SRF Cavities

The National High Magnetic Field Laboratory (MagLab, CSA CSM) is playing a role in a nationwide effort to make human-scale particle accelerators for a host of applications. And now, with a $1 million grant from the US Department of Energy, scientists at the lab's Applied Superconductivity Center (ASC) are developing...

Advancing Tissue Engineering with 3-D Cryoprinting

The importance of additive manufacturing (AM) and 3-D printing has increased in almost every field of engineering, including biomedical engineering, a field where researchers are advancing applications such as 3-D cryoprinting. The technology is poised to develop into an important step in tissue engineering as it can produce biological tissues...

NASA Awards Funding to Support Professional Development Programs for STEM Educators

NASA’s Glenn Research Center in Cleveland has awarded approximately $125,000 to schools and organizations to launch professional development programs for science, technology, engineering and math (STEM) educators. The award is intended to strengthen STEM programs for K-12 teachers across Ohio through the use of NASA content. The grant also includes...

Quantum Data Takes a Ride on Sound Waves

Yale scientists have created a device that uses sound waves to store quantum information and convert it from one form to another, all inside a single integrated chip. The device allows a superconducting artificial atom, or qubit, to exchange energy and quantum information with a high-frequency bulk acoustic wave resonator....

FCC and the Superconducting Magnets of the Future

Physicists at CERN are counting on new magnets, ones capable of generating fields of 16 Tesla or more, to increase the energy of its future circular colliders. To achieve these levels, researchers working on CERN's Future Circular Collider (FCC) study have developed a test station known as FRESCA2, a dipole...

Injecting New Life into the LHC

CERN launched the LHC Injectors Upgrade (LIU) project in 2010 to prepare its accelerator complex for the immense challenges of the HL-LHC. Now, in a report appearing in CERN Courier, engineers from the project have provided a status update. In addition to enabling the necessary proton and ion injector chains...

Helium II

Helium II (He II) refers to the second liquid phase of the most abundant helium isotope (4He). Helium II is also referred to as superfluid helium. Helium II occurs once the temperature of the liquid helium drops below 2.17K. The phase transition between the first liquid phase of Helium (referred...

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?
