Willy Wölfli (1930–2014)
Looking back on Willy Wlfli's scientific achievements is not an easy task. However, to fully understand his remarkable contributions to AMS, one has to begin with a look at his professional career. Influenced by the worldwide crises of the 1930s and 1940s, which also left their mark on Switzerland, Willy Wlfli
A Simple Way to Upgrade a Compact Radiocarbon AMS Facility for 10 Be
A simple way to upgrade the Peking University 500kV NEC radiocarbon facility (CAMS) for 10 Be measurements is presented. In a first phase, a silicon nitride foil as passive boron degrader was mounted in front of the electrostatic deflector near the focal plane of 10 Be. The Si detector at the end of the beam line was replaced with a high-resolution ΔE-E res gas ionization chamber. In addition, a Faraday cup for the measurement of 9 Be 1+ was inst…

Ams 14 C Age Determinations of Tissue, Bone and Grass Samples from the Ötztal Ice Man
14 C ages of samples from the Ötztal Ice Man, found on the Hauslabjoch in the Tyrolean Alps in September 1991, were determined using accelerator mass spectrometry (AMS). Uncalibrated 14 C ages of 4555 ± 34 bp, 4560 ± 65 bp and 4535 ± 60 bp were measured on tissue (mean of four samples), bone and grass, respectively, from the Ice Man. The mean of all of our measurements is 4550 ± 27 bp
CalibETH
A computer program for convenient calibration of radiocarbon dates has been developed. The program has a simple user interface, which includes pull-down menus, windows and mouse support. All important information, such as calibration curves, probability density function and results, in text form, are displayed on the screen and easily can be rearranged by the user. Two versions of CalibETH, one for an IBM-PC and one for the Macintosh, are availab…
Measurement of Small Volume Oceanic 14 C Samples by Accelerator Mass Spectrometry
A technique for 14 C measurement of small volume (0.5L) oceanic water samples by Accelerator Mass Spectrometry (AMS) is described. Samples were taken from a CTD/rosette system used for standard hydrographic work. After CO 2 extraction and target preparation, the samples were measured at the Zürich tandem accelerator facility. On the basis of 14 C data from samples collected on a station in the northern Weddell Sea, the precision of the measuremen…
AMS Radiocarbon Dates on Foraminifera from Deep Sea Sediments
14 C ages were determined on samples of foraminifera separated from cores from three areas of the tropical Pacific (East Pacific Rise, Oontong Java Plateau, and South China Sea). Analyses were made on four planktonic species and on mixed benthics. The purpose of the multiple analysis on planktonic species is to assess the importance of artifacts resulting from the bioturbation-abundance change couple, from the bioturbation-partial dissolution cou…
Archaeologic Sherd Dating
Sherds can be dated by four independent methods: 14 C beta counting on associated material, accelerator mass spectrometry on carbon traces on and within the sherd, thermoluminescence studies on minerals within the sherd, and stylistic form. Age analyses of materials and sherds from several sites are shown in this work. Each technique has its own frequently encountered non-laboratory sources of error. A combination of at least two independent tech…
The ETH/SIN Dating Facility
The ETH/SIN AMS dating facility is routinely used for 10 Be, 14 C, 26 Al, and 36 Cl measurements. The present status and performance of this facility are reviewed and some of its major applications summarized
Dating Polar Ice by 14 C Accelerator Mass Spectrometry
Results of 14 C/ 12 C ratio measurements on CO 2 extracted from air bubbles in polar ice are presented. The samples investigated originate from the Dye 3, South Greenland, deep ice core and span approximately the last 10,000 years. The results are calibrated with tree-ring records. The 14 C ages are compared with information obtained from seasonal variations of ice-core parameters and rheologic model calculation
Radioisotope Dating with the ETHZ-EN-Tandem Accelerator
During the last three years the ETH-EN-tandem accelerator facility has been adapted for the quantitative determination of the rare isotopes 14 C and 10 Be in mg samples. The goal of this project is to routinely achieve a 1% accuracy when measuring 14 C/ 12 C ratios with a minimum expenditure of human resources and beam time. The concept is similar to that proposed by Purser and Henley (1978). The early evolution of this dating facility was descri…
Temporal 10 Be Variations in Ice
10 Be (T 1/2 = 1.5·10 6 y) is mainly produced in the atmosphere by cosmic ray spallation reactions on nitrogen and oxygen. About 70 % of the production takes place in the stratosphere. 10 Be becomes attached to aerosols within a very short time. If 10 Be is produced in the stratosphere some latitudinal mixing occurs. Most of the 10 Be is transferred to the troposphere during spring and early summer when, mainly at median latitudes, large stratosp…
