Researchers Develop Circuit Refrigerator for Quantum Computers

Cooling has proven to be a major concern for engineers developing quantum computers, but now a research team at Finland's Aalto University says it has invented a quantum circuit refrigerator that could reduce errors in quantum computing. Quantum computers differ from the computers that we use in that, instead of...

Ball Aerospace Developing Cryostat for GUSTO

NASA has chosen Ball Aerospace to design and build a cryostat for its Galactic/Extragalactic Ultralong Duration Balloon (ULDB) Spectroscopic Terahertz Observatory mission, or GUSTO. The mission, led by the University of Arizona, will measure emissions from the interstellar medium, helping scientists to determine the life cycle of interstellar gas in...

Nikkiso Acquires Cryogenic Industries

Nikkiso Co., Ltd. has announced its acquisition of Cryogenic Industries (CSA CSM), a group of product and service companies supporting both liquefaction and separation plants for air gases and small-scale plants for LNG liquefaction. The deal is worth an estimated $440 million and is expected to close in August.

CERN Celebrates Linac 4 Completion

The European Organization for Nuclear Research (CERN) celebrated the completion of its Linac 4 during a ceremony on May 9. The new accelerator is expected to allow the Large Hadron Collider (LHC) to reach higher luminosity by 2021. The machine is almost 90 meters long, sits 12 meters below the...

Pulsating Heat Pipes Hold Promise for Future Space Flight

As space flight missions move away from tanks filled with cryogenic liquids towards cryocoolers to provide cooling for cryogenic payloads, new heat transport technologies are needed to cool distributed systems. Researchers have recently investigated pulsating (or oscillating) heat pipes (PHPs) at laboratories and universities in several countries. Possible applications for...

Advancing Cryogenic Temperature Instrumentation

Ryan Oliver explores the evolution of the techniques used to measure and control temperature since this time, with a focus on cryogenic temperatures as a tool, rather than techniques used by those working on defining temperature scales.

Joule-Thomson Effect

The Joule-Thomson (JT) effect is a thermodynamic process that occurs when a fluid expands from high pressure to low pressure at constant enthalpy (an isenthalpic process). Such a process can be approximated in the real world by expanding a fluid from high pressure to low pressure across a valve. Under...

Current Leads

One of the challenges of using superconducting magnets is the connection of the magnet to a room temperature power supply. This is accomplished via current leads. The trick is that current leads should ideally have a low heat leak, since they connect room temperature to cryogenic temperature, while at the...

Multilayer Insulation

Multilayer insulation (also referred to as superinsulation) is a key component in the reduction of heat leak to cryogenic systems due to thermal radiation. MLI consists of a series of uncooled reflective surfaces placed in the vacuum space between two surfaces, one warmer than the other. Generally speaking, for ideal...

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...

Definition or max temp which defines “cryogenic”?

Please help me with a definition: I am calculating material and fabrication costs for a quote for a hydrocarbon meter station.

Thermal shock on steel cylinder when dropped into liquid nitrogen

We are a research team at the University of South Florida, studying the “thermal shock” on a steel cylinder when it is dropped into liquid nitrogen. We want to make sure that the thermocouple does not get influenced by the surrounding LN2. Any advice?

Getter materials to absorb out gassed materials?

Here’s one for the scientists: We would like to sell vacuum insulated pipe for high temperature fluid applications. Are there any good getter materials that we can place in the vacuum space of our VJP to absorb outgassed materials at elevated temperatures?

Data on Carbon Fibres Reinforced Plastic at temperatures between 4 and 300K.

I am looking for data on Carbon Fibres Reinforced Plastic at temperatures between 4 and 300K. I would appreciate it if someone could give me some hints on where to find it.
