A Review of Cryogenic Sensors for Emerging Applications

For cryogenic applications, the most common types of temperature sensors are resistors, diodes and thermocouples. Choosing a sensor depends on application, response time and response range, sensitivity, stability, ease of use, packaging and optimum cost.

A Progressive Building Block Testing Approach to Validate Designs for Cryogenic Structures

CTD's support of the James Webb Space Telescope program involved a progressive building block approach, starting with simple materials and bonded joint tests, and followed by testing of sub-assemblies, prototypes and proof testing of flight hardware.

CSA Participates in ‘Science Works’ Outreach Event

On October 4 and 5, 2013, CSA participated in “Science Works: Cool Jobs, Hot Careers” at the Museum of Science and Industry in Chicago. The aim of the event was to provide opportunities for youth to engage with STEM professionals as a way to spark interest in STEM-related career paths.

Researchers achieve breakthrough in superconducting cable technology for future Navy ship applications

Researchers at Florida State University’s Center for Advanced Power Systems (CAPS) achieved a major breakthrough in their ongoing high temperature superconducting cable project that will lead to increased power generation and reduced weight for future naval vessels and aircraft.

A superconductor-surrogate earns its stripes

Understanding superconductivity, whereby certain materials can conduct electricity without any loss of energy, has proved to be one of the most persistent problems in modern physics.

Metamaterials may offer route to room-temperature superconductivity

A new way of making high-temperature superconductors that is based on metamaterials has been proposed by physicists at the University of Maryland.

Dewar

A dewar is a type of cryostat named after Sir James Dewar, the researcher who first developed the concept of a vacuum insulated container with silvered walls to reflect thermal radiation. Dewar was the first to liquefy hydrogen, and he created the device to store his discovery. The thermos bottle...

Stirling and Gifford-McMahon Cryocoolers

Stirling and Gifford-McMahon (GM) cryocoolers are two of the most commonly used cryocoolers in cryogenics. Both devices have a significant industrial base and operate at a wide range of temperatures and capacities. The thermodynamic cycles for both of these cryocoolers are quite similar. The Stirling cycle consists of a compressor,...

Liquefied Natural Gas (LNG)

A significant commercial application of cryogenics is the liquefaction, transport and storage of natural gas. Liquefied Natural Gas (LNG) is generally 95 percent methane with a few percent ethane and much lower concentrations of propane and butane. LNG liquefies at 111.6 K. Unlike many applications of cryogenics, the motivation for...

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...
