In an email to its members, the Compressed Gas Association announced the formation of a new Process Safety Committee to address process safety concerns and gaps that affect the industrial gas industry.

Auguste Acquires Taylor-Wharton’s European Operations

Auguste Cryogenics SK s.r.o. has acquired Taylor-Wharton International’s European Operations, including a cryogenic pressure vessel manufacturing facility, Taylor-Wharton Slovakia s.r.o., and the related warehouse and office complex of Taylor-Wharton Germany GmbH. Auguste says all employees have been retained and that the facilities will continue to operate under the Taylor-Wharton brand...

XFEL Commissions New X-ray Laser

Engineers at European XFEL, a large international research facility with 11 European member countries, have begun commissioning a 3.4-km-long underground X-ray laser. When operational, the laser will generate extremely short and bright X-ray light flashes that will enable new views of the structure and fast processes of the nanocosmos. Applications...

2016 Nobel Prize in Physics Awarded

The Royal Swedish Academy of Sciences awarded the 2016 Nobel Prize in Physics to David J. Thouless, F. Duncan M. Haldane and J. Michael Kosterlitz, three laureates who have used advanced topological methods to study unusual phases of matter, such as superconductors, superfluids or thin magnetic films. Thanks to their...

Spallation Neutron Source Marks a Decade of Research

Oak Ridge National Laboratory (CSA CSM) celebrated a decade of research at its Spallation Neutron Source (SNS) with an event on September 22. The SNS features a linear accelerator and accumulator ring. It sent the first protons to its one-of-a-kind mercury target in April 2006 and over the last decade...

Helium II

Helium II (He II) refers to the second liquid phase of the most abundant helium isotope (4He). Helium II is also referred to as superfluid helium. Helium II occurs once the temperature of the liquid helium drops below 2.17K. The phase transition between the first liquid phase of Helium (referred...

Bose-Einstein Condensate

A Bose-Einstein condensate, first proposed in 1925 by Albert Einstein based on work done by Satyendra Nath Bose (the same Bose from whom the term boson is derived), is a super-cold state of matter in which almost all of the individual atoms have “condensed” down to the lowest possible quantum...

Cold Technology for Pest Control

While it does not reach temperatures cold enough to be called cryogenic, carbon dioxide snow is at the heart of a new way of dealing with unwanted pests. It utilizes a quick freezing process that takes advantage of the properties of carbon dioxide snow and has a number of benefits...

Cryogenic Finishing

The following 3 articles discuss the uses and procedures of various type of cryogenic finishing. 1) By Robin A. Rhodes, Cryogenic Institute of New England, Inc. rrhodes@nitrofreeze.com Cryogenic Deflashing is employed to remove undesired residual mold flash that remains on molded parts after they are removed or ejected from the...

Seeking recommendations for commercial sensors

I would like to measure vibrations in small LHe cryostats. Could anybody recommend commercial sensors which would be suitable for the purpose? I am interested in the frequency range between 1Hz and a couple of KHz, with particular attention to the low frequency side.

Estimating cost of carbon steel, pure helium storage tanks

In order to perform an indicative cost assessment of our helium cryogenic plant (still in the design phase), I need an estimation of the cost of carbon steel room temperature pure helium storage tanks. The storage pressure is 20 bar. Can anyone give me suggestions about how to estimate the...

Supplier of pressure sensor that works down to 4.2 K

In an actual experiment we would like to measure the static pressure in a cryostat in the range between one and four bar. Therefore we are looking for some (more or less) cheap pressure sensors that work in liquid helium in the pressure range up to five bar. Unfortunately all...

Looking for reference/textbook suggestions

Can you suggest some reference textbooks for practical thermodynamics applications in cryogenic fields? I need textbooks with cryogenics calculations and examples, dimensioning procedures, second principle applications in cryogenics, heat load calculations, cryogenic pump application, etc. Do such books exist? Does any similar source of information exist?
