Kivonat:
Lowering the ion energy in AMS systems allows a size reduction for these
systems. For radiocarbon a system that operates at an ion energy of 45
keV was built at ETH. This energy can be provided by the cesium
sputtering ion source and allows an instrument that doesn't need a
further acceleration stage in the spectrometer. The low energy lead to
challenges for the beam transport through the system which limits the
overall measurement efficiency. The performance of the prototype system
is shown and physical limitation of the system are explained. The
reduced effort for radiocarbon measurements provided by such an
instrument allow applications in new research fields. To support these
applications a new gas feeding system was developed that allows a high
sample throughput and also the measurement of very small samples.
