Mattia Checchin earns first prize at SRF 2015 for poster on accelerator cavity work

Mattia Checchin, a PhD student at the Illinois Institute of Technology conducting his thesis research at Fermilab, won first prize for his poster on superconducting radio frequency (SRF) accelerator cavity performance at the recent 17th International Conference on Radio Frequency Superconductivity (SRF 2015) in Whistler, Canada.

New multi-SQUID device cuts costs, improves sensitivity

Physicists in the United Kingdom have built a multi-SQUID device that can operate at 77K, the boiling point of liquid nitrogen. According to research published in Applied Physics Letters, the new device outperforms the industry standard niobium/aluminium trilayer single-SQUIDS maintained at 4.2K. "Since our SQUID arrays operate at 77K using...

Is magnetic cooling the future of cool?

Ames Laboratory scientists almost 20 years ago announced groundbreaking progress in magnetic refrigeration and yet there are still no known commercially available products that use a magnetic cooling system. Magnetic cooling exploits the magnetocaloric effect, a temperature change of a material caused by exposing it to a changing magnetic field,...

Master Bond announces new one component epoxy

Master Bond on October 13 unveiled a new single part adhesive sealant for use in a variety of applications in aerospace, electronic, optical, specialty OEM and related industries. The Master Bond Supreme 10HTF-1 offers cryogenic serviceability from 4K to +400°F and resists an array of chemicals such as water, fuels,...

New atomic absorption spectrometer helps redefine the kelvin

A team of Australian scientists has developed an atomic absorption spectrometer that provides a new way to determine Boltzmann’s constant, a number that relates the motion of an individual atom to its temperature. The research, published in Nature Communication contributes to a worldwide scientific effort to redefine the kelvin, the...

DOE announces new accelerator stewardship funding opportunities

The US Department of Energy made available an estimated $4 million in grants on October 13 with a Funding Opportunity Announcement (FOA) for research opportunities associated with its Accelerator R&D Stewardship Program. Research funded under this FOA could lead to advances is High Energy Physics (HEP), but the grants are...

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...

TS diagram for helium

Where can I obtain a really big, nice TS diagram for helium ?

Reliability and mounting of electronic substrates at low temperatures

I am currently working on the design of a focal plane assembly to be implemented on a small satellite (4 EMCCD detectors) to be operated at -80°C (which is not really cryogenic and likely still considered boiling hot for most of you :-). As it is passively cooled, the assembly...

Are 3D drawings included in the sale of a cryogenic plant?

I have a question concerning the 3D drawings of a cryogenic plant. The integration of the 3D drawings of a plant with the 3D main model of a new laboratory or a new facility can be a complex work that takes a lot of time. I would like to know...

Looking for a source of LOX impact testing to ASTM D2512

I have been looking for a source of LOX impact testing to ASTM D2512. I am aware of NASA and White Sands, but am looking for a commercial entity doing the work. No luck so far, even calling a lot of the folks on the CSA website. Any referrals will...
