Report on Compact Linear Collider
An interview with Dr. Philippe Lebrun, former head of the Accelerator Technology Department for the Large Hadron Collider (LHC), where he discusses plans for the Compact Linear Collider (CLIC). CLIC is in the conceptual design phase, not yet approved. Although aiming at the same goal for physics, i.e. colliding electrons...
Fermilab participates in USA Science & Engineering Festival
From Fermilab Today, November 15: A group of preteen girls entered the Fermilab exhibit tent on the Washington, D.C. Mall and pushed forward to stare at the numbers whizzing by on an electronic counter. 6,000. 6,015. Their foreheads crinkled.

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...
