Dark Energy Survey Publicly Releases Data Trove

Scientists on the Dark Energy Survey publicly released data from the project's first three years during a special session held at the American Astronomical Society meeting in Washington DC. The release includes information on about 400 million astronomical objects, from distant galaxies billions of light-years away to stars in our...

Separate Research Teams Advance Quantum Simulators

Researchers at the Harvard-MIT Center for Ultracold Atoms and at the Joint Quantum Institute at the University of Maryland have announced complementary advances in quantum studies that constitute a major step towards the realization of large-scale quantum machines.

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...

Space Cryogenics

Space cryogenics is, somewhat obviously, the application of cryogenics to space exploration and science. The use of cryogenics in space optimizes the launching of vehicles, provides power and life support to spacecraft and is critical for many scientific observations.Space cryogenics has a number of challenges and has driven both pure...

Exergy

The science of thermodynamics plays a major role in cryogenics. It underlies the various refrigeration cycles, from Carnot to Brayton (Cold Facts Vol. 32 No. 2) and Joule-Thomson, is a fundamental part of the definition of terms such as coefficient of performance (Cold Facts Vol. 31 No. 1) and even...

Cryogenic Treatment

Cryogenic treatment is the process of cooling materials to cryogenic temperatures temporarily to improve their material properties at room temperature. This is distinct from cooling materials down to cryogenic temperatures to take advantage of phenomena such as superconductivity that only occur at cryogenic temperatures. Cryogenic treatment, sometimes also referred to...

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?
