ITER Passes 50 Percent Marker on Journey to First Plasma

The International Thermonuclear Experimental Reactor (ITER), a project to prove that fusion power is both sustainable and producible on a commercial scale, reached a major milestone at the end of 2017 when construction work towards “First Plasma” passed 50 percent.

MSU Establishes Cryogenic Initiative at FRIB

The Facility for Rare Isotope Beams (FRIB) should garner a lot of attention in 2022 when it first delivers the intense beams that scientists will use to study everything from nuclear astrophysics to fundamental interactions and applications for society including in medicine, homeland security and industry. But the facility is...

Argonne’s Advanced Photon Source Unravels Mummy, Leaves Linens Untouched

Northwestern University scientists and students are working to unravel the mysteries of a small female mummy, including how her body was prepared 1,900 years ago in Egypt, what items she may have been buried with, the quality of her bones and the composition of a foreign material present in her...

Niowave’s Electron Linacs Target New Projects

From the quaint neighborhood streets that run alongside its perimeter, Niowave, Inc. appears as unassuming as the converted local elementary school from which it operates. But inside, where water fountains and toilets still perch low to the ground and footsteps echo off hallway lockers, its employees have assumed the once...

Researchers Observe Four-dimensional Physics in Two Dimensions

Physicists from two research groups have announced techniques that allow materials in four-dimensional space to be studied in two-dimensional systems. Both experiments dealt with the quantum Hall effect, a phenomenon that has been at the root of three Nobel Prizes in physics.

Qatargas Begins Operations, Finalizing Integration of Qatar Petroleum and RasGas

Qatar Petroleum announced the official start of operations of Qatargas following the completion of its integration with RasGas, a process that began in December 2016. The announcement was made by Saad Sherida Al-Kaabi, president & CEO of Qatar Petroleum, during a press conference held at QP headquarters.

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...

The various gases have useful and sometimes fascinating applications in food industry. “The food industry is not a homogenous industry. The needs of customers processing hamburger vs. poultry vs. strawberries vs. seafood, for...

Primary Standards

Elie K. Track Hypres, Inc. elie@hypres.com http://www.hypres.com/ Primary standards involve the exact definition and realization of units of measurement for various quantities, time, length, mass, voltage, resistance, current, etc. International agreements based on the latest scientific knowledge define those units, and their realizations vary depending on the unit itself. For...

Shrink Fitting

Robin A. Rhodes Cryogenic Institute of New England, Inc. rrhodes@nitrofreeze.com Shrink fitting, (or “compression fitting” as it is sometimes called), is a method used to insert a pin or bushing into a housing or other assembly requiring an extremely tight tolerance fit. It can be used as an alternative to...

Telecommunications

From the Winter 2004 issue of Cold Facts magazine The recent M-Calc IV — 4th Industry Assessment workshop discussing military and commercial applications for low-cost cryocoolers, held in November in San Diego, highlighted progress being made in cryogenics as applied in telecommunications. The reliability and long lifetime of projects now...

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...
