Study Sheds Light on the Peculiar ‘Normal’ Phase of High Temperature Superconductors

In a paper published in Science this month, a research team from the Department of Energy’s SLAC National Accelerator Laboratory and Stanford University reported on an experiment that probed the normal state of superconductors more accurately than ever before, discovering an abrupt shift in the behavior of electrons in which...

First Magnet Installed for the ALPS II Experiment at DESY

The international Any Light Particle Search (ALPS) II collaboration installed the first of 24 superconducting magnets in mid-October, marking the start of the installation of a unique particle physics experiment to look for dark matter. Located at DESY, the German research center in Hamburg, it is set to start taking...

CERN Council Appoints Fabiola Gianotti to Second Term of Office as CERN Director General

At its 195th session, the CERN Council selected Fabiola Gianotti, the organization’s director-general, for her second term of office. The appointment will be formalized at the December session of the Council, and Gianotti’s new five-year term will begin on January 1, 2021. This is the first time in CERN’s history...

Cryomech Breaks Ground on New Manufacturing Facility

Cryomech, Inc. (CSA CSM) recently broke ground on their new 76,000-square foot manufacturing facility in DeWitt NY. The custom designed building will provide space for continued growth and innovation in the cryogenics industry. Cryomech also plans to grow staff in both manufacturing and administration. According to the current build schedule,...

Fermilab, International Partners Break Ground on New Beamline for the World’s Most Advanced Neutrino Experiment

On November 14, the US Department of Energy’s Fermi National Accelerator Laboratory (CSA CSM) joined with its international partners to break ground on a new beamline that will help scientists learn more about ghostly particles called neutrinos. The beamline is part of the Long-Baseline Neutrino Facility (LBNF), which will house...

Magnet Doubles Hydrogen Yield from Water Splitting

Using nothing more than a $10 magnet, José Ramón Galán-Mascarós and his researchers at the Institute of Chemical Research of Catalonia (ICIQ) in Spain have doubled the hydrogen output of a water-splitting electrolyzer. If the approach can be scaled up, it has the potential to slash the costs of producing...

Regenerators

Regenerators or regenerative heat exchangers are a key component of cryocoolers such as pulse tube cryocoolers (Cold Facts, August 2014). Regenerator performance greatly affects the coefficient of performance of cryocoolers. Improvements in regenerator design and, in particular, regenerator materials have been an important factor in the improvement of the performance...

Pulse Tube Cryocoolers

The development of pulse tube cryocoolers has been a significant topic of research and development over the past 20 or so years. Pulse tube cryocoolers have a number of advantages over other types of cryocoolers and are now available commercially. In order to understand pulse tube cryocoolers, it’s best to...

Thermal Expansion

Thermal expansion refers to the change in size (length or volume) that a material undergoes as its temperature changes. In cryogenic systems this effect can be quite large and must be allowed for in the design. In isotropic materials, which include most engineering materials, the thermal expansion is the same...

Cryogenics in Space

Peter Kittel University of California-Berkeley pkittel@cal.berkeley.edu Space Cryogenics is the application of cryogenics to space missions. These applications fall into two broad areas, supporting space science missions and supporting the space transportation infrastructure. Science applications: The atmosphere is opaque to much of the electro-magnetic spectrum. In space, the absence of...

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...

Separated layers of ice over a pipe

I want to know that why there are different layers of ice over a pipe carrying a cryogenic fluid, each layer separated with clear marks / lines? What do these layers signify?
