ACCELERATOR MASS SPECTROMETRY
The 4th East Asia AMS Symposium
16-18, December, 2011
Takeda Hall, The University of Tokyo

PREFACE

AMS (Accelerator Mass Spectrometry) is a powerful tool for investigation in various research fields including earth science, environmental science, archaeology, material science, life science and also nuclear safeguard. Data of rare isotopes precisely quantified by AMS often play a decisive role in these research fields and opening new frontier of the study. The number of AMS facilities as well as researchers concerning with AMS have been increasing recently, especially in the Asian region. Reflecting this situation, the East Asia AMS Symposium (EA-AMS) had started in 2006 at Tsukuba University, Japan. Following EA-AMS-2 (2007 in Korea), EA-AMS-3 (2009 in China), we here plan EA-AMS-4 at The University of Tokyo, Japan. We spare 3days for this symposium in December this year and prepare several specific sessions described below. Every researcher concerning AMS or being interested in AMS is expected to choose and contribute to any session(s). We hope this symposium will be the kick off of new expansion of your research. We are looking forward to seeing you in December!

SCHEDULE OUTLINE

SESSION TOPICS

1. New facilities and status reports

2. Technological innovation and improvement

3. General application

4. 14C application: Earth and environmental sciences

Convener:
Y. Yokoyama (The University of Tokyo)

The session welcomes contributions relating wide ranges of Earth and Environmental scientific topics using radiocarbon as a tracer or a chronological measure.

Confirmed speakers:
Prof. Timothy Jull (University of Arizona)
Prof. Min-Te Chen (National Taiwan Ocean University)
Prof. Liping Zhou (Peking University)
Dr. Naohiko Ohkouchi (JAMSTEC)

5. 14C application: Archaeology

Convener: M. Yoneda, The University of Tokyo

6. Long-term records of beryllium 10 and chlorine 36

Convener:
K. Horiuchi (Hirosaki University)

Long-term records of beryllium 10 and chlorine 36 contribute to the elucidation of the history of cosmic ray variations and climate-driven changes in the fallout/depositional systems in the atmosphere, land and ocean. They can be also utilized for radiometric and/or stratigraphic dating back to the past ten million years. This session aims to present the latest long-term records of beryllium 10 and chlorine 36 obtained from natural archives such as ice cores and sediments, and to discuss about their implications and future directions of the related studies. "Long-term" does not only mean "geological". The records in "historical" or "observational" era are also welcome.

7. 129I applications: Natural and Modern system

Convener:
H. Matsuzaki (The University of Tokyo)

Iodine-129/127 isotope system draws much interest for the several tenth Ma scale dating or potential proximity of carbon dynamics. It is also play an important role for the environmental assessment of humanfs nuclear activities and also for the evaluation of the effect of the nuclear accident like the Fukushima dai-ichi accident. This session aim at reviewing current research outcomes and anticipating future research area using Iodine isotopes.

Confirmed speaker:
Dr. Xiaolin Hou (Technical University of Denmark)
