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...

Dewar

A dewar is a type of cryostat named after Sir James Dewar, the researcher who first developed the concept of a vacuum insulated container with silvered walls to reflect thermal radiation. Dewar was the first to liquefy hydrogen, and he created the device to store his discovery. The thermos bottle...

Stirling and Gifford-McMahon Cryocoolers

Stirling and Gifford-McMahon (GM) cryocoolers are two of the most commonly used cryocoolers in cryogenics. Both devices have a significant industrial base and operate at a wide range of temperatures and capacities. The thermodynamic cycles for both of these cryocoolers are quite similar. The Stirling cycle consists of a compressor,...

Liquefied Natural Gas (LNG)

A significant commercial application of cryogenics is the liquefaction, transport and storage of natural gas. Liquefied Natural Gas (LNG) is generally 95 percent methane with a few percent ethane and much lower concentrations of propane and butane. LNG liquefies at 111.6 K. Unlike many applications of cryogenics, the motivation for...

You are encouraged to read Cryo Central’s History...

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...

I was looking for suppliers of regenerator materials. Can you please provide a list of vendors for: • Lead spheres • Bronze screen discs • Rare earth materials and spheres Thank you in advance for any help you can provide.

Containing ice accumulation while recovering helium

We are implementing a system to recover helium from our Janis ST-500 continuous flow LHe cryostat. The recovery system uses standard 1/4″ plastic tubing, which we connect directly to the cryostat’s exhaust port. The problem with this setup is that the gas is still quite cold as it leaves the...

Looking for some advice regarding cryogenic modeling in ANSYS FEA software

I am looking for some advice regarding cryogenic modeling in ANSYS FEA software. I have been trying to use the Transient Thermal module, in workbench 14.5, to model the cooling of a device in a dilution fridge. I have approximate values for the cooling power of each plate in the...
