Ten Ways Fermilab Advanced Science and Technology in 2020

More than 3,500 researchers from around the world collaborate with the US Department of Energy’s Fermi National Accelerator Laboratory (CSA CSM) to develop state-of-the-art technologies and solve the mysteries of matter, energy, space and time. Here is a look at 10 ways Fermilab advanced science and technology in 2020.

Simulating Subatomic Physics on a Quantum Computer

When two heavy ions collide inside a particle accelerator, they produce a near-perfect fluid through which an assortment of fundamental particles swim. For scientists to accurately simulate even a tiny drop of this hot and dense subatomic brew with a classical computer, it would take longer than the age of...

Manchester Group Discovers New Family of Quasiparticles in Graphene-Based Materials

A group of researchers led by Sir Andre Geim and Dr Alexey Berdyugin at the UK University of Manchester have discovered and characterized a new family of quasiparticles named "Brown-Zak fermions" in graphene-based superlattices. The study follows years of successive advances in graphene-boron nitride superlattices which allowed the observation of...

Preparatory ‘Pre-lab’ Proposed for ILC

On September 10, the International Committee for Future Accelerators announced the structure and members of a new organizational team to prepare a “pre-laboratory” for an International Linear Collider in Japan. The ILC International Development Team, which consists of an executive board and three working groups—governing the pre-lab setup, accelerator, physics...

REBCO HTS Wire Manufacturer SuperPower Relocates to New Facility

On August 24, SuperPower Inc. (CSA CSM), a wholly owned subsidiary of Japan’s Furukawa Electric Company, Ltd., announced that it has completed its move and is now operating from a new facility in Glenville NY. The company is a world leader for the development and manufacturing of REBCO-based second generation...

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...

Air Separation and Liquefaction

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...
