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.

Liquid Hydrogen

Hydrogen becomes a liquid at 20K and 1 bar. Liquid hydrogen (LH2) is an important substance in industry, transportation and research. Industrial uses of hydrogen include applications in the electronics, glass, chemical and metal processing fields. In these applications, the hydrogen is generally used as a room temperature gas but...

Superconducting Radiofrequency Cavities

Superconducting radio frequency (SRF) cavities represent an important application of cryogenics and superconductivity. SRF cavities are a technology for accelerating charged particle beams via the transfer of radiofrequency (RF) energy to the beams via resonant structures. As such, they are frequently found in large particle accelerators used for scientific research....

Thermal Radiation Shields

Actively cooled thermal radiation shields are a common feature of cryostats whose lowest temperature is less than 77K. These shields, which typically operate at temperatures between that of LN2 and 40K, block thermal radiation from higher temperatures from reaching lower temperature cryogenic components or fluids. Since the heat radiated from...

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...

An Issue of Pressure and Flow Rate in a Supply Tank

Please help solve this problem: A supply tank requires a vaporizer to generate sufficient pressure to pump stored fluid up into a vehicle or tank. The available head is limited as the tank level falls and it is important to minimize the system pressure drop to maintain the desired flow...

Using MLI on VJ Line Joints or Cryo Storage Tanks

When installing Multi Layer Insulation (MLI) blankets on VJ line joints or cryo storage tanks should they be wrapped and tied down tight or loose? These are usually pre-cut to size. Also should they have an access hole at the point of where the molecular sieve is installed to help...
