Ariel Atom 4 - Driving Event

Realization of Cold-Electron Bolometers with Ultimate

A cloud of cold sodium atoms (bright spot at center) floats in a trap. atoms would be captured in a trap consisting of focused laser beams, with the atomic motion being damped until the temperature of the atoms reached the microkelvin range. That paper was my first introduction to laser cooling, although the idea of laser cooling (the reduction of random thermal velocities using radiative forces) had In laser cooling, the basic principle used to cool down atoms is to slow them down. We know, each atomic species has thermal energy associated with it. So, slowing down an atom would lower its kinetic energy and thermal energy, which will eventually lead to a decrease in its temperature, hence cooling it down.

The ALPHA collaboration at CERN has succeeded in cooling down antihydrogen atoms – the simplest form of atomic antimatter – using laser light. The technique, known as laser cooling, was first demonstrated 40 years ago on normal matter and is a mainstay of many research fields.
