The Open House will feature interactive demonstrations, exhibits and tours of world-class, cutting-edge research facilities. This is a great opportunity...

Maglab Researchers Demonstrate Method to Reduce Quantum Bit Decoherence

An interdisciplinary collaboration of physicists and chemists from the National High Magnetic Field Laboratory (MagLab) (CSA CSM) has demonstrated a way to improve the performance of the powerful but persnickety building blocks of quantum computers (called quantum bits or qubits) by reducing interference from the environment. The research, which may...

UPS Adds Cryogenic Shipping to Its Temperature-Sensitive Portfolio In Europe

UPS has launched its Temperature True® Cryo system in Europe, providing healthcare customers there access to end-to-end product protection and the capability to ship parcels in a cryogenic environment. The system uses cryogenic containers from Cryoport, a manufacturer of custom built liquid nitrogen dry vapor shippers, to keep products frozen...

Major Breakthrough in MRI Scan Technology for Lung Disease

Scientists at the University of Nottingham have taken a major step towards providing a much clearer picture of lung disease thanks to new scanning technology developed at its Sir Peter Mansfield Imaging Center. The new process makes the spaces inside lungs show up on a magnetic resonance imaging (MRI) scan...

Particle Physics Groups Again Signal Support for ILC

The Asia-Pacific High Energy Physics Panel (AsiaHEP) and the Asian Committee for Future Accelerators (ACFA) have issued a joint statement urging a redoubled international effort to realize the International Linear Collider (ILC) at KEK, Japan's High Energy Accelerator Research Organization. The joint announcement follows a similar one made by the...

Cryogenics Goes Radioactive in Search for Big Bang Neutrinos

Princeton University's Plasma Physics Laboratory (PPPL) is readying a facility to detect Big Bang neutrinos by capturing them in tritium, a radioactive isotope of hydrogen. The state-of-the-art project is named PTOLEMY, both as an homage to the second century Greek astronomer and as an acronym for Princeton Tritium Observatory for...

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...

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...

Liquefied Natural Gas

Liquefied Natural Gas as it relates to the Field of Cryogenics John W. Bonn VJ Systems, LLC johnbonn@vjsystems-lic.com Today the world is looking for a cleaner fuel and Liquefied Natural Gas (LNG) plays a large part in achieving this goal. LNG in a liquid form is at -162°C (-259°F) and...

Food Processing

Cryogenics and Food The industrial gas industry provides a host of products and services related to food. The various gases have useful and sometimes fascinating applications in food industry. “The food industry is not a homogenous industry. The needs of customers processing hamburger vs. poultry vs. strawberries vs. seafood, for...

Seeking recommendations for commercial sensors

I would like to measure vibrations in small LHe cryostats. Could anybody recommend commercial sensors which would be suitable for the purpose? I am interested in the frequency range between 1Hz and a couple of KHz, with particular attention to the low frequency side.

Estimating cost of carbon steel, pure helium storage tanks

In order to perform an indicative cost assessment of our helium cryogenic plant (still in the design phase), I need an estimation of the cost of carbon steel room temperature pure helium storage tanks. The storage pressure is 20 bar. Can anyone give me suggestions about how to estimate the...

Supplier of pressure sensor that works down to 4.2 K

In an actual experiment we would like to measure the static pressure in a cryostat in the range between one and four bar. Therefore we are looking for some (more or less) cheap pressure sensors that work in liquid helium in the pressure range up to five bar. Unfortunately all...

Looking for reference/textbook suggestions

Can you suggest some reference textbooks for practical thermodynamics applications in cryogenic fields? I need textbooks with cryogenics calculations and examples, dimensioning procedures, second principle applications in cryogenics, heat load calculations, cryogenic pump application, etc. Do such books exist? Does any similar source of information exist?
