FDA accepts BioCision’s ThawSTAR master file

The US Food and Drug Administration (FDA) this month accepted the Device Master File (MAF) submission for BioCision's ThawSTAR automated cell thawing system. The ThawSTAR MAF encompasses information pertaining to the specifications, materials and quality and manufacturing processes used in producing the ThawSTAR system.

Study shows economics impact of cryogenics in UK

A study by Warwick Economics & Development (WECD) that was commissioned by the Science & Technology Facilities Council shows that the UK's strong cryogenics community delivers substantial economic impact to the country's economy. Based on supply chain analysis, WECD estimates that sectors broadly associated with cryogenics represent 17 percent of...

Researchers create first superconducting graphene

Physicists at the University of British Columbia have created the first-ever superconducting graphene sample by coating it with lithium atoms. Although superconductivity has already been observed in intercalated bulk graphite—3-D crystals layered with alkali metal atoms, based on the graphite used in pencils—inducing superconductivity in single-layer graphene has until now...

ATLAS and CMS experiments shed light on Higgs properties

Three years after the announcement of the discovery of a new particle, the so-called Higgs boson, the ATLAS and CMS collaborations at CERN have combined their analyses of the data collected in 2011 and 2012 to draw the sharpest picture yet of this novel boson. ATLAS and CMS presented their...

Hybrid DC circuit breaker solution based on cryogenic technique

A hybrid DC circuit breaker comprised of a cryogenic contactor in series with a superconductor has recently been developed at NASA Glenn Research Center. This circuit breaker combines mechanical and solid-state technology to meet the needs of certain DC power system applications.

Issue No. 33 of Superconductivity News Forum is online

The quarterly Issue No. 33 of the Superconductivity News Forum (SNF) dated July 2015 is now available online at the IEEE Council on Superconductivity's website. The publication of the present issue was delayed to accommodate selected presentations and preprints from the recent CEC/ICMC 2015 and ISEC 2015.

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....

Suppliers of regenerator materials

I was looking for suppliers of regenerator materials. Can you please provide a list of vendors for: • Lead spheres • Bronze screen discs • Rare earth materials and spheres Thank you in advance for any help you can provide.

Containing ice accumulation while recovering helium

We are implementing a system to recover helium from our Janis ST-500 continuous flow LHe cryostat. The recovery system uses standard 1/4″ plastic tubing, which we connect directly to the cryostat’s exhaust port. The problem with this setup is that the gas is still quite cold as it leaves the...
