text TANGR2015 Heidelberg Second international workshop on Tracer Applications of Noble Gas Radionuclides in the Geosciences Heidelberg University, March 26 - 29, 2015 Kirchhoff-Institute Institute for Physics of Environmental Physics 1 Preface TANGR2015 is a workshop on the progress in the technique and application of Atom Trap Trace Analyis (ATTA). It is a follow-up to the rst TANGR workshop, TANGR2012, which was held at the Argonne National Laboratory, Argonne, USA, in June 2012. It is organized in response to recent technical advances and new applications of Atom Trap Trace Analysis (ATTA), an analytical method for measuring the isotopes 81Kr, 85Kr, and 39Ar. The primary aim of the workshop is to discuss the technical progress of ATTA and thereby enable innovative and timely applications of the noble gas radionuclides to important scientic problems in earth and environmental sciences, e.g. in the elds of groundwater hydrology, glaciology, oceanography, and paleoclimatology.

Start: 10.45am at bus stop Marstallstrasse 6 4 Abstracts Next Generation Atom Trap Trace Analysis Apparatus at Argonne Peter Mueller Physics Division, Argonne National Laboratory, Argonne, IL 60517, USA The long-lived noble-gas isotope 81Kr is an ideal tracer for old water and ice samples in the age range of 105106 years, a range beyond the reach of 14C. Based on the development of Atom Trap Trace Analysis (ATTA), 81Kr-dating is now available to the earth science community at large. Since 2012, we have utilized our third generation ATTA instrument to participate in 17 international collaborative projects, and have analyzed more than 150 groundwater and ice samples that were extracted from all seven continents. At the same time, we have explored and implemented new techniques leading towards improvements on both sample size requirement and measurement precision. In particular, reduced sample sizes are anticipated to enable more extensive studies of ice samples where larger quantities are not easily accessible, such as those originating from ice cores. In this talk I will present our recent developments and future plans for the ATTA laboratory at Argonne.
