Cold Testing Underway on ITER’s Toroidal Field Coils

Engineers from SIMIC S.p.a., a contractor based in Italy, have wrapped up the first round of cold testing the toroidal field coils manufactured for ITER, a process that involved submitting the coil winding pack to a thermal cycle between room temperature and 80 K.

New Superconducting Cable Surfaces from Research Supporting US Navy

A research team from Florida State University’s Center for Advanced Power Systems and the Colorado-based Advanced Conductor Technologies LLC has demonstrated the first high-temperature superconducting direct current power transmission cable using ACT’s Conductor on Round Core (CORC) cable technology. The cables enable transmission of vast amounts of power at high...

Stirling Power Generator Recovers Both Cold Energy and Waste Heat

Plans for recovering LNG cold energy have become an important focus in the LNG industry and show great potential for increasing energy efficiency and reducing carbon emission.

Companies Adapt Cryocooler Technology for New Applications

Cryocoolers are making inroads into commercial applications and are getting closer to our everyday lives. It is well known in the cryogenics community that cryocoolers have been in increasing demand for wider applications.

Researchers Hunting Exoplanets with Superconducting Arrays

The key to revealing the exoplanets tucked away around the universe may just be locked up in the advancement of Microwave Kinetic Inductance Detectors (MKIDs), an array of superconducting detectors made from platinum sillicide and housed in a cryostat at 100 mK.

Cryocoolers, a Brief Overview

Cryocoolers are a type of refrigerator designed to reach cryogenic temperatures. Engineers use the term most often for smaller systems, typically no larger than table-top size, with input powers less than about 20 kW.

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...

Cryogenics in Space

Peter Kittel University of California-Berkeley pkittel@cal.berkeley.edu Space Cryogenics is the application of cryogenics to space missions. These applications fall into two broad areas, supporting space science missions and supporting the space transportation infrastructure. Science applications: The atmosphere is opaque to much of the electro-magnetic spectrum. In space, the absence of...

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?
