Transformative ‘Green’ Accelerator Achieves World’s First 8-pass Full Energy Recovery

Scientists from Cornell University and the US Department of Energy’s (DOE) Brookhaven National Laboratory (BNL) have successfully demonstrated the world’s first capture and reuse of energy in a multi turn particle accelerator, where electrons are accelerated and decelerated in multiple stages and transported at different energies through a single beamline....

The Future of Particle Accelerators May Be Autonomous

Operators at the Linac Coherent Light Source (LCLS) particle accelerator, part of SLAC National Laboratory at Stanford University in California, looked into how they were spending their time managing the machine. They tracked the hours they spent on tasks like investigating problems and orchestrating new configurations of the particle beam...

60 Years of DESY: From Hamburg Particle Accelerator to Global Research Center

For the past 60 years, fundamental research has been carried out at the Deutsches Elektronen-Synchrotron (DESY) in Hamburg-Bahrenfeld. In those 60 years, DESY has become a world leader in accelerator technology, structure research, particle physics and astroparticle physics. DESY has developed pioneering technologies, which have been used by scientists from...

Jefferson Lab to be Major Partner in Brookhaven Electron Ion Collider Project

The Department of Energy (DOE) announced that it has taken the next step toward the construction of an Electron Ion Collider (EIC) in the United States. DOE announced that the collider will be sited at DOE’s Brookhaven National Laboratory in Upton NY. In addition, DOE’s Thomas Jefferson National Accelerator Facility...

The Pocket-Sized Particle Accelerator

The accelerator-on-a-chip is just a prototype, but its design and fabrication techniques can be scaled up to deliver particle beams accelerated enough to perform cutting-edge experiments that don’t require the power of a massive accelerator. By placing these chips in a series, researchers from SLAC National Laboratory and Stanford University...

Helium II

Helium II (He II) refers to the second liquid phase of the most abundant helium isotope (4He). Helium II is also referred to as superfluid helium. Helium II occurs once the temperature of the liquid helium drops below 2.17K. The phase transition between the first liquid phase of Helium (referred...

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...

Seeking alloy that keeps elastic property down to 10K

I am looking for a metal (alloy) that supports high temperatures (at least 1600K) and keeps its elastic property at low temperatures down to 10K. Rhenium is a good one because it does not become brittle. But it is quite expensive. Pure tungsten and molybdenum enter in the brittle regime...

Searching for a freezer that does not need electricity

I’m student of University of Barcelona. We do technical cryogenic research and we are searching for a cryogenic portable freezer that does not need electricity. We can’t find any company that offers something like this. The product we are looking for is the typical portable freezer for food or drinks...
