Canadian Researchers Working on Novel MRI for ISS

The Canadian Space Agency has awarded a research team at the University of Saskatchewan a contract to design and engineer an ankle-sized MRI device for the International Space Station. The device, according to the team, will ultimately monitor the bone health of astronauts during prolonged space trips, where weightless conditions...

Jlab Research Shows Protons under More Pressure Than Neutron Stars

Scientists at the Thomas Jefferson National Accelerator Facility (CSA CSM) recorded the first measurement of pressure distribution inside a proton and reported in journal Nature that inside every proton in every atom in the universe is a pressure cooker environment that surpasses the atom-crushing heart of a neutron star.

Brooks Expands Freezer Line to Support Cryobags

Brooks Life Sciences, a division of Brooks Automation (CSA CSM), announced the launch of its BioStore III Cryo automated freezer for 250ml cryobags at the International Society for Cellular Therapy Conference (ICCT 2018) in Montreal. The latest version of its freezer brings simple, automated management for 250mL cryobags to the...

UK Researchers Form First National Biobank

The UK’s National History Museum announced a new initiative to collect and preserve the DNA of thousands of animals at a biobank called CryoArks. The collection of zoological tissue will provide a central hub for researchers across the UK, according to the museum, providing access to cells and DNA from...

NOAA Reports Cooling Failure aboard GOES-17

The National Oceanic and Atmospheric Administration has reported a performance issue with the cooling system aboard GOES-17, a multibillion-dollar weather satellite launched in March. NOAA engineers encountered the issue during commissioning of the satellite’s Advanced Baseline Imager instrument.

DOE Funds International Cryogenic Dark Matter Experiment, Construction Underway at Canada’s SNOLAB

The US Department of Energy Office of Science and the National Science Foundation have approved funding and the start of construction for the SuperCDMS SNOLAB experiment, that will begin in the early 2020s to hunt for light dark matter particles. DOE’s Fermi National Accelerator Laboratory (CSA CSM) will play a...

Stability

Stability refers to the ability of a device employing superconductors to remain in its superconducting state after part of the superconductor transitions back to its normal conducting state due to a disturbance. While the concept can apply to many superconducting devices—transmission lines, generators, motors, etc.—it is most commonly considered in...

Cable-in-Conduit Conductors

Cable-in-Conduit Conductors (CICC) are a common form of superconducting cable used in large-scale applications. There are several varieties of CICCs, but they all consist of many small, stabilized superconducting wires contained within a conduit through which a coolant (typically supercritical He II) flows. Figure 1 shows the cross section of...

Bayonet Coupling

A bayonet coupling is a demountable joint that allows for quick and easy connection and disconnection of cryogenic components, including transfer lines, cryostats, liquefiers and refrigerators. Bayonets provide a number of advantages, chief among them the ability to connect and disconnect the bayonets while components they connect are still at...

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...

Presence of alloying elements in tool steels

I want to expand my knowledge of cryogenics in general and tool steels in particular. Specifically, I am keenly interested in learning about the presence of alloying elements in tool steels and how their presence in various combinations affects the performance of tool steels after cryogenic treatment.

Pros and cons of barcoding samples

I was wondering if I could ask for input on pros and cons of barcoding. We are in the process of trying to decide if we should start barcoding our samples and I’m just not sure if this is feasible for our organization. We have numerous sites all over the...

Purity level of helium gas stream in cryo plant purification system

I would like to know what the principal methods and the relative instrumentation to check the purity level of helium gas stream in the purification system of a common helium cryogenic plant are. What principles are these instruments based on? And what are their principal characteristics?

LN2 for cryopreservation through controlled rate freezing of samples

I am the cryogenic specialist for a stem cell bank in Greece. I am trying to find the minimum requirements (purity, humidity, etc.) of liquid nitrogen for cryopreservation through controlled rate freezing of biological samples.
