An infrared laser, made visible by vapour, is split by a birefringent crystal into one vertical and one horizontal beam, demonstrated with an ArTTA Atom Trap Trace Analysis system currently at the Kirchhoff-Institute for Physics in Heidelberg, Germany, December 7, 2018. Atom Trap Trace Analysis for 39Ar is an ultra-sensitive detection method based on principles of quantum mechanics and found its first application in dating ground water and ice samples.

Atom Trap Trace Analysis for 39Ar is an ultra-sensitive detection method based on principles of quantum mechanics. Scientists extract Argon, a Noble Gas, from the air bubbles trapped in the ice. After the extraction, scientists catch and count the rare Ar39 atoms to determine the age of the air and in result the age of the ice. REUTERS/Lisi Niesner SEARCH "AUSTRIA GLACIERS" FOR THIS STORY.
