Maglab Scientists Use NMR in Battle Against Influenza

Scientists at the National High Magnetic Field Laboratory (Maglab) (CSA CSM) have detailed the mechanism that activates influenza and permits it to reproduce in human cells. The research, published in Structure, shows for the first time how protons move through the virus’s M2 proton channel and portends the development of...

LHC ends 2015 with a cliffhanger

The final Large Hadron Collider results of the year are in. Particles circulated in the LHC at CERN on December 13 for the last time in 2015, and, two days later, the two large general-purpose experiments, ATLAS and CMS, presented their results from LHC Run 2. Both experiments saw an...

QuAIL project announces advances in quantum tunneling achieved on D-Wave 2X

NASA welcomed members of the news media on December 8 to tour its Quantum Artificial Intelligence Laboratory (QuAIL) at Ames Research Center, providing attendees a rare glimpse inside the facility that houses the 1,097-qubit D-Wave 2X quantum computer. Researchers on NASA’s QuAIL team are using the system to investigate areas...

Improved LUX sensitivity helps redefine dark matter search parameters

Scientists working on the Large Underground Xenon (LUX) dark matter experiment are closer to ruling out the possibility of dark matter detections at low-mass ranges. The new findings come after researchers enhanced LUX's ability to look for WIMPS, or weakly interacting massive particles, and thereafter reexamined data collected during LUX's...

TRIUMF and KEK strengthen partnership to advance physics research

At a signing ceremony hosted on December 4 at the Canadian Embassy in Japan, the heads of Canada’s TRIUMF and Japan’s KEK signed a new partnership agreement to enhance research collaborations between the two centers and promote joint projects in the areas of subatomic physics, accelerator science and materials science.

Researchers developing shoebox-sized particle accelerator

The Gordon and Betty Moore Foundation in November awarded $13.5 million to Stanford University for an international effort, including key contributions from the Department of Energy’s SLAC National Accelerator Laboratory, to build a working particle accelerator the size of a shoebox. The technique, based on a technology known as “accelerator...

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...

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...

An Issue of Pressure and Flow Rate in a Supply Tank

Please help solve this problem: A supply tank requires a vaporizer to generate sufficient pressure to pump stored fluid up into a vehicle or tank. The available head is limited as the tank level falls and it is important to minimize the system pressure drop to maintain the desired flow...

Using MLI on VJ Line Joints or Cryo Storage Tanks

When installing Multi Layer Insulation (MLI) blankets on VJ line joints or cryo storage tanks should they be wrapped and tied down tight or loose? These are usually pre-cut to size. Also should they have an access hole at the point of where the molecular sieve is installed to help...

Separated layers of ice over a pipe

I want to know that why there are different layers of ice over a pipe carrying a cryogenic fluid, each layer separated with clear marks / lines? What do these layers signify?
