LHC collides ions at new record energy

After the successful restart of the CERN Large Hadron Collider (LHC) and its first months of data taking with proton collisions at a new energy frontier, the LHC is moving to a new phase, with the first lead-ion collisions of Run 2 at an energy about twice as high as...

The Cryogenic Treatment Database, CSA's resource for research and information in the field of cryogenic treatment, has been updated. We encourage you to visit the database and share this information with researchers and others in the field.

Authorities call for regulation of cryotherapy

Investigation into the recent death of Chelsea Ake-Salvacion in a liquid nitrogen cryotherapy chamber at RejuvenIce in Henderson NV points to oxygen deprivation as the cause of death. In the wake of this tragic accident, authorities are calling for steps to regulate the use of cryotherapy, which has recently been...

LCLS researchers discover new dimension to high temperature superconductivity

A team led by scientists at the US Dept. of Energy (DOE)’s SLAC National Accelerator Laboratory observed a new type of "charge density wave" after combining powerful magnetic pulses with some of the brightest X-rays on the planet. The resulting 3-D effect appears closely linked to high temperature superconductivity, though...

Obituary: Former BCC Chairman Harry Jones

Professor Harry (Henry) Jones died on August 24, 2015, at 70 years of age. He was a professor of condensed matter physics at the Clarendon Laboratory, Oxford University, where he worked for 44 years until his retirement in 2012. Jones also led the High Magnetic Fields and Superconductivity Group, the...

Dimitri Delikaris named head of CERN Cryogenics Group

Dimitri Delikaris was appointed head of the CERN Cryogenics Group (CRG) on November 1, replacing Laurent Tavian. The CRG is responsible for the development, operation and maintenance of cryogenic systems used for the LHC collider, the fixed targets program and related cryogenic test facilities.

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...

Wind Tunnels

Dr. Robert Kilgore The development of the cryogenic wind tunnel is one of many significant breakthroughs in both cryogenics and wind-tunnel technology made during the past millennium. Interest in the development of high-speed commercial and military aircraft resulted in a review of problems of flow simulation in transonic wind tunnels...

History of Cryogenics

From the Fall 1999 issue of Cold Facts magazine Millennium Breakthroughs A variety of CSA members give different perspectives on the past millennium: What were the most significant breakthroughs in cryogenics during the past millennium? Prof. R.G. Scurlock, Kryos Technology, scurlock@soton.ac.uk (“Breakthrough” = way through obstacles — Oxford English Dictionary)...

Cryobiology

Andreas Sputtek Past President Society for Cryobiology sputtek@uke.uni-hamburg.de or http://www.sputtek.de/. The word cryobiology (from the Greek words “cryo” = cold, “bios” = life, and “logos” = science) literally signifies the science of life at low temperatures. In practice, this field comprises the study of any biological material or system (e.g.,...

Cryogenic Insulation

James E. Fesmire Cryogenics Test Laboratory NASA Kennedy Space Center james.e.fesmire@nasa.gov Introduction In today’s world, the use of cryogenics and low-temperature refrigeration is taking a more and more significant role. From the food industry, transportation, energy, and medical applications to the Space Shuttle, cryogenic liquids must be stored, handled, and...

Presence of alloying elements in tool steels

I want to expand my knowledge of cryogenics in general and tool steels in particular. Specifically, I am keenly interested in learning about the presence of alloying elements in tool steels and how their presence in various combinations affects the performance of tool steels after cryogenic treatment.

Pros and cons of barcoding samples

I was wondering if I could ask for input on pros and cons of barcoding. We are in the process of trying to decide if we should start barcoding our samples and I’m just not sure if this is feasible for our organization. We have numerous sites all over the...

Purity level of helium gas stream in cryo plant purification system

I would like to know what the principal methods and the relative instrumentation to check the purity level of helium gas stream in the purification system of a common helium cryogenic plant are. What principles are these instruments based on? And what are their principal characteristics?

LN2 for cryopreservation through controlled rate freezing of samples

I am the cryogenic specialist for a stem cell bank in Greece. I am trying to find the minimum requirements (purity, humidity, etc.) of liquid nitrogen for cryopreservation through controlled rate freezing of biological samples.
