Researchers Develop Cryogenic Coffee Grinding Technology

Skoltech Ph.D. Dima Smirnov and his colleagues from St. Petersburg, Alexander Saichenko, Vladimir Dvortsov, Mikhail Tkachenko and Maxim Kukolev developed a cryogenic cooling technology and combined it with a cryogenic grinding technique to produce, for the first time ever, retail cryoground coffee.

Honoring the Hugets

After 42 years of continued leadership and direction, Laurie and Werner Huget have retired from CSA. For decades, the Hugets have overseen CSA’s day-to-day operations, organized conferences and workshops attended by professionals from around the world and facilitated countless short courses for the cryogenics community. We invite you to continue...

JanisULT, Formerly Janis Research, Launches New Website

In August 2020, Janis Research Company, LLC (CSA CSM) announced a formal change in company name to JanisULT (a trading name of American ULT Cryogenics, LLC) following the successful sale of their laboratory cryogenics business to Lake Shore Cryotronics (CSA CSM). On March 12, the company announced their updated website,...

IceCube Detection of a High Energy Particle Proves 60-Year-Old Theory

On December 6, 2016, a high energy particle called an electron antineutrino hurtled to Earth from outer space at close to the speed of light carrying 6.3 petaelectronvolts of energy. Deep inside the ice sheet at the South Pole, it smashed into an electron and produced a particle that quickly...

From Second Sound to Music: A Special Composition Inspired by Advanced Physics

CSA Board Chairman, Dr. John Weisend II, and composer M.E. Edgerton present a unique representation of advanced physics with a one-of-a-kind musical arrangement based on data produced from advanced particle accelerators.

Improving Cryogenic Pipes to Reduce Wasted Energy, Money at BRUGG

BRUGG (CSA CSM), a leading cryogenic piping company based in Wunstorf, Germany, engineers pipe systems for various industrial applications while minimizing heat leak and saving resources—monetary and otherwise. Where BRUGG’s low temperature applications are only one part of a larger product portfolio, the vast temperature differences between cryogenic and ambient...

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...

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?
