Argon Trap Trace Analysis

• Age dating of environmental systems via ³⁹Ar
• Applied Quantum Technology
• Ultrasensitive detection method using quantum optics

The goal of Argon Trap Trace Analysis, ArTTA, is to measure the ³⁹Ar concentration of ice and water samples to gain information about the dynamics of environmental systems. Due to ³⁹Ar having an extremly low abundance, an ulta-high selectivity is required which is achieved by counting single atoms in a magneto-optical trap. Using these quantum optical methods for environmental research is a unique example of applied quantum technology. In the next years the understanding of the generation of metastable atoms and further improvements of the laser cooling efficiency will be part of our research as well as expanding our capabilities to the radiokrypton isotope ⁸⁵Kr.

The ArTTA project at the Heidelberg University is a cooperation of the group of Markus Oberthaler from the Kirchhoff Institute for Physics and Werner Aeschbach from the Institute for Environmental Physics.
