“Orange” You Excited for SLAC’s New X-Ray Laser?

See upgrades to SLAC National Accelerator Laboratory’s X-ray laser, including some of the 37 cryomodules to be completed, in a collection of photos showcasing its trademark orange styling, and learn more about the experiments it will enable.

SOFIA Soars to Observe the Universe

SOFIA, the Stratospheric Observatory for Infrared Astronomy, is a unique plane-based observatory housed inside a 747 aircraft. A joint project between NASA, Universities Space Research Association, and the German Aerospace Center-DLR since 1997, it takes advantage of the stratosphere to eliminate the absorbing effect atmospheric water has on infrared observations....

Cryogenics Takes Center Stage for PIP-II at Fermi National Accelerator Laboratory

Construction of the Proton Improvement Plan II (PIP-II) is underway at Fermi National Laboratory (CSA CSM) in Batavia IL. Since the groundbreaking ceremony on March 15, the laboratory team has been preparing for the beam that will contribute to international high energy physics research experiments. The superconducting radio-frequency (SRF)-powered linear...

Cryoablation of Breast Cancer Cells Offers Non-Invasive Option

Breast cancer patients at Cedars-Sinai hospital in Los Angeles have a promising cryogenic option to significant intrusive surgeries thanks to cryoablation. Dr. Peter Julien, chief of thoracic imaging and tumor ablation at the S. Mark Taper Foundation Imaging Center at Cedars-Sinai, has been conducting a study using cryoablation to treat...

Fermilab Achieves World-Record Field Strength for Accelerator Magnet

Scientists at the Department of Energy’s Fermilab (CSA CSM) have achieved the highest magnetic field strength ever recorded for an accelerator steering magnet, setting a world record of 14.1 teslas, with the magnet cooled to 4.5 kelvin or minus 450 degrees Fahrenheit. Lawrence Berkeley National Laboratory held the previous record...

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...

Magnetic Levitation

From http://www.superconductors.org. Magnetic-levitation is an application where superconductors perform extremely well. Transport vehicles such as trains can be made to “float” on strong superconducting magnets, virtually eliminating friction between the train and its tracks. Not only would conventional electromagnets waste much of the electrical energy as heat, they would have...

Superconductivity

From Superpower website. History of Superconductivity Superconductivity was discovered in 1911 by the Dutch physicist, Heike Kammerlingh Onnes when he was able to liquefy helium by cooling it to 4 Kelvin, or -452°F. This enabled him to cool other materials close to absolute zero and investigate their electrical properties. He...

Medical Applications of Cryogenics

Neutron Therapy Cryogenics is at the heart of nuclear accelerators. Accelerators such as Fermilab’s Tevatron make neutron therapy for cancer possible. From Fermilab Today 4/20/09: Fermilab currently offers neutron therapy. But staff at Fermilab designed and built the proton accelerator used by the nation’s first hospital-based treatment center to use...

Nuclear Physics

Al Zeller National Superconducting Cyclotron Lab (NSCL) at Michigan State University zeller@nscl.msu.edu Cryogenics has a long history in nuclear physics. The technology has its origins in the use of cold traps for maintaining a vacuum, which is required to prevent beam loss and for generating high voltages used in acceleration....

Cryogenic thermophysical property data

I am in search of information regarding cryogenic thermophysical property data, specifically, Thermal Conductivity, Thermal Expansion, Stiffness and Modulus, in the 20K range. My list of materials include: Ti-6AL-4V (ELI), Al 6061-T651, and Invar (36%, plus any other composition which might have data available). Other materials which would be helpful...
