Scope of the Program

AMS-9 succeeds the tradition of the past AMS conferences that began from Rochester (1978)and continued through Argonne (1981), Zurich (1984), Niagara-on-the-Lake (1987), Paris(1990), Canberra and Sydney (1993), Tucson (1996), and most recently Vienna (1999). The
conference focuses on both technical and application advances in AMS that have occurred in thepast three years since the Vienna conference.
Two pre-conference workshops are planned. The first one focuses on physical and chemical
behavior of meteoric 10 Be in the environmental system. The second one is on applications ofcosmogenic nuclides to problems in geoarchaeology. Details are described later.
Themes of sessions are similar to previous conferences: new AMS facilities; status of current
AMS facilities; technical progresses (ion source, detection methods, sample preparation, dataacquisition and analysis, background reduction, etc.); AMS standards and reference materials;
international inter-comparison; radiocarbon calibration; general applic ations (oceanography,
ground water, atmosphere, sediments, ice, archaeology, cultural property science, biomedical
and biochemical sciences, nuclear safeguards, heavy nuclides, material science, forensic
problems, etc.); and future directions. Proposing a new theme is welcomed.
Poster presentation is as usual a very important way of showing new results and exchanging
ideas and opinions. Many poster contributions are welcomed and a competition for the bestposters is planned.
Conference Language
The official conference language is English.

Pre -Conference Workshops
Workshop-I:
Workshop on meteoric 10Be in environmental systems: applications and limitations tochronologic and rate studies
The University of Tokyo
Bunkyo, Tokyo, Japan
Friday, September 6, 200210

Be is a major nuclide in the field of AMS. There are many potential applications using
meteoric 10 Be, which is produced mainly in the upper atmosphere. Meteoric 10 Be delivered byrainfall occurs at much higher concentrations and undergoes transfer processes that are distinct
from in situ 10 Be.
Detailed examinations of physical and chemical behaviors of 10Be in various environmental
systems are needed for proper use of 10Be as a precise clock or a reliable tracer. There are manyquestions about transfer processes of 10 Be precipitated on land.
This workshop will focus on physical and chemical behaviors of 10 Be in surficial environments.
Topics include:- precipitation from the atmosphere and transfer back to the atmosphere,- mobility and mean residence time in soil,- interaction with ground waters,- chemical and mineralogical studies on the elemental Be,- availability and interpretation of 10 Be concentration data in specific site studies such as rainfall,soils, terrestrial (e.g., aeolian, fluvial, estuarine, lacustrine) and marine sediments, ice, etc.
Presentations on practical applications of 10 Be such as the chronology of surface and buriedsoils, tracing of eroded soil particles, and comparison of sediment yields from eroding basinsare encouraged.
Topics related to in-situ 10 Be are NOT intended to be included.
Persons who will contribute to this workshop will be requested an extended abstract inaddition to the short abstract that is required for the general paper submission for AMS-9.
Detailed information will be sent to those who apply papers for this workshop by the end ofJune, 2002.

Workshop-II:
Workshop on applications of cosmogenic nuclides to problems in geoarchae ology
National Museum of Japanese History
Sakura, Chiba prefecture, Japan
Saturday, September 7, 2002
We have organized a small workshop on some topical issues in geoarchaeology and also novel
uses of cosmogenic radionuclides for underground and underwater applications. This workshop
will precede the AMS-9 Conference to be held in Nagoya,
The workshop will have 3 themes:
1. Interpretation of multiple dates for archaeological sites and related issues
2. Application of cosmogenic nuclides other than radiocarbon to archaeological studies.
3. Application of cosmogenic nuclides underground and underwater
The first theme is related to the problems in interpreting series of 14 C dates, which sometimes isessential in reconstructing the archaeological facts. Examples with which we may be confronted
include ones such as how to interpret results that do not appear to be consistent with otherarchaeological observations and how to incorporate other dates by different methods such as
thermoluminescence (TL) and optically stimulated luminescence (OSL) and electron spinresonance (ESR) methods.
A second theme is the use of cosmogenic nuclides other than 14 C in the study of archaeologicalsamples. There have been a few studies that have attempted to apply in-situ-produced nuclides
to archaeological problems or the use 10Be to trace the provenance of pottery, for example.
The third theme is the use of in-situ cosmogenic nuclides underground and underwater forgeology and geoarchaeology. This includes the studies such as a land-bridge study withcosmogenic nuclides underwater and burial dating with in-situ cosmogenic nuclides.
Between the morning and afternoon sessions, the participants can view the museum exhibitions.

Other Travel Information
JR pass
Japanese railway (JR) system is a convenient way to travel in Japan but it is expensive.
Participants who attended the pre-conference workshops or who arrived in Japan through the
Narita International Airport are strongly recommended to use the JR train (“Shinkansen” –bullet train) from Tokyo to Nagoya. It takes less than 2 hours from Tokyo station to Nagoya
station (10,580 Yen one way). If you would like to use a train service in Japan, you may want toconsider purchasing a JR pass (Japan Rail Pass), available for 7, 14, 21 days, depending on yourschedule to stay in Japan. The prices are 28,300 Yen (7 days), 45,100 Yen (14 days) or 57,700
Yen (21 days). You can use all JR system including express trains and “Shinkansen” withreserved seat with JR pass. A JR pass has to be purchased outside Japan by non-Japanese
residents. See detail http://www.jreast.co.jp/jrp.
Rental Car
Traveling around by car is very expensive in Japan. We have good motor way services in Japan.
However, you are normally charged when you use motorways. It is not recommended forparticipants from abroad to use a rental car in Japan, unless you know the traffic system in Japanvery well.
Accommodations, Social Activities, Post Conference Tours
For easy of payment, the registration, accommodation, conference tour, accompanying persons’programs, farewell party and post-conference tours are being handled by the Japan Travel
Bureau (JTB) Event & Convention Service (JECS). JECS will have representatives present
throughout the conference at the conference desk at Nagoya University. Further informationfrom JECS is given in another documents. For conference registration, hotel reservation andarrangements for other activities, please fill out the separate application forms: “Registration”
and “Accommodation and Other Activities” and send the forms directly to JECS. Do not send
these forms to the AMS-9 conference address. Only paper submission forms and abstracts
should be sent to the AMS-9 conference address.

Some of the sessions or topics have been proposed personally or by groups:
AMS standards and reference materials (Session topics No.4) by Drs. Kunihiko Nishiizumi
and Marian Scott. E-mail: kuni@ssl.berkeley.ac.jp, marian@stats.gla.ac.uk
Isotopic primary and secondary standards and reference materials are vital for the provision ofhigh quality measurements and for quality assurance in the natural sciences. We invite
submission of oral presentations and posters on the subject of AMS standards and referencematerials. Topics might include amongst others: new standards, the comparison and calibrationof standards, laboratory inter-comparison, problems with existing standards and the needs for
new materials.
Nuclear safeguards (Session topics No. 6-10) by Drs. Claudio Tuniz, Masanobu Nakamura andYasuo Nagashima. E-mail: claudio.tuniz@dfat.gov.au, nakamura@ne.scphys.kyoto-u.ac.jp,
nagashima@tac.tsukuba.ac.jp
This topic includes the use of AMS in nuclear non-proliferation applications, particula rly those
based on the use of AMS for detecting 236 U and other actinides in the environment.
Forensic problems (session topics No. 6-13) by Dr. Ugo Zoppi. E-mail: ugo@ansto.gov.au
This topic deals with the 14 C bomb pulse to estimate carbon sources and/or production year offood, medicine, harmful drugs, etc., for forensic applications.
We also have a few proposals to support sessions. Any proposals and suggestions to scientificprogram of AMS-9 will be welcomed.

We have measured 14 C ages of more than 8,000 samples from such various research
fields as archaeology, anthropology, geology, geography, hydrology, oceanography, etc., for the
past 16 years with a GIC Tandetron AMS system, at the Dating and Materials Research Center,
Nagoya University. In 1996, we have introduced another Tandetron AMS system which was thethird AMS machine built by High Voltage Engineering Europe (HVEE), B.V., the Netherlands.
During the installation of the machine, we have experienced some troubles. A serious one wasthat the accelerated positive beam was emitted so much downward that the equipped verticalstirrers could not control the beam correctly. After such troubles had been overcome, we
conducted successfully the performance tests of the spectrometer in January, 1999. The
14
C/13C/12 C ratios were measured for six graphite targets, in ten minutes each, and for six cycles
repeatedly. The targets were prepared from the HOx-II oxalic acid standard by the Univ. of
Christian -Albrechts, Germany, and provided to the HVEE for the performance tests at Nagoya.
The 14 C count rate was typically 80 cps and the 12 C3+ and 13 C3+ currents were 280 nA and 290
nA, respectively, at the terminal voltage of 2.5 MV. The reproducibilities of 14 C/12 C and 13 C/12 C
ratio measurements for the six targets were very good, resulting in the figures in relative (one)standard deviation of 0.17% and 0.03%, respectively [1].
We have started reliability tests on 14 C measurements with our HVEE tandetron for
IAEA standards and some other samples with known age. Our initial application programs of
the high-performance AMS system would be;(1) annual ring samples of trees related with volcanic eruptions are to be dated precisely. The
14
C ages will be used for an accurate age determination of those volcanic events by the wiggle
matching method.
