Hot Qubits Made in Sydney Break One of the Biggest Constraints to Practical Quantum Computers

A group of researchers led by Professor Andrew Dzurak at the University of New South Wales, Sydney, has developed a proof-of-concept quantum processor unit cell on a silicon chip that works at 1.5 Kelvin—15 times warmer than the main competing chip-based technology using superconducting qubits being developed by Google, IBM...

Tempshield Publishes “How to Care for Cryogenic Gloves and PPE in Age of Infection”

Whether mitigating the risk of COVID-19, Norovirus or the common flu, it’s vital that researchers and other front-line workers can avoid infection while doing their jobs. As such, proper care and cleaning of cryogenic gloves, cryogenic protection, face shields and other personal protective equipment (PPE) cannot be overlooked. Tempshield (CSA...

FDA Clears ‘World’s First’ Portable, Low Cost MRI following Positive Clinical Research

The US Food and Drug Administration has provided clearance to the “world’s first” bedside MRI system. Connecticut-based Hyperfine said it will begin shipping its portable, low field modalities this summer. The machine’s 510(k) FDA clearance was granted as Yale researchers reported accurate and safe results from tests involving brain readings...

Linde Cryogenics Supplies First of Kind Helium Recovery System to Sumitomo Cryogenics

In late March, Linde Cryogenics (CSA CSM) delivered a modular helium recovery system to Sumitomo Cryogenics of America, Inc's (CSA CSM) Allentown PA production facility. By capturing and recycling helium from production operations, the system is expected to reduce consumption of purchased helium at the facility by 70%. The system...

SLAC Researchers Use Cryo-EM to Discover Giant Cavity in Key Tuberculosis Molecule

Researchers from the Department of Energy’s SLAC National Accelerator Laboratory using Cryo-EM technology have discovered a strange new feature of a protein that’s thought to be important in the treatment of tuberculosis. The protein contains a highly unusual “huge” interior pocket that appears capable of passing a wide range of...

Champaign-Urbana MTD Purchases Two Hydrogen Buses

The Champaign-Urbana Illinois Mass Transit District (MTD), has ordered two hydrogen fuel cell buses from New Flyer of America. The contract calls for New Flyer to supply two hydrogen fuel cell electric sixty-foot Xcelsior CHARGE H2™ heavy duty transit buses in the Champaign, Urbana and Savoy regions of the state....

Transfer Lines

Transfer lines may in some real sense be thought of as the cryogenic fluid analogy of current leads. While current leads carry electrical power to where it’s required in a cryogenic system, transfer lines do the same with cryogenic fluids. Transfer lines range in complexity from very simple U-tubes containing...

Zero Boiloff

Zero Boil Off cryostats are those that contain liquid cryogens but are designed to eliminate or vastly reduce the boil off of the liquid. These cryostats combine some of the advantages of Cryogen-Free systems (e.g. ease of use and long operational lifetime) with the advantages associated with a reservoir of liquid...

Cryomodule

Cryomodule is a term that is most commonly used to refer to cryostats that contain superconducting radio frequency (SRF) cavities. Such cavities are used to accelerate charged particle beams and are a major component of modern particle accelerators. Using the term cryomodule to refer to cryostats containing SRF cavities appears...

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...

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...
