Our scientific and service activities are performed on our three main accelerator facilities.
The TANDEM facility is based on a 6 MV HVEC EN-Tandem accelerator, which was installed at ETH Zurich in the early 1960s for nuclear physics experiments. Over the past decades, the focus of the activities has moved to applied physics, mainly accelerator mass spectrometry (AMS) and material sciences. Today, the TANDEM is used for AMS measurements of nuclides with isobaric interference (e.g. 36Cl). In addition the TANDEM offers ion beams of nearly all elements over a wide range of energies used for materials analysis (RBS, ERDA, NRA, PIXE, STIM, Channeling, MeV-SIMS) and for ion implantations.
The 500 kV TANDY facility was built at LIP in collaboration with National Electrostatics Corporation (NEC; Middelton, Wisconsin USA) in 1997 to demonstrate the feasibility of 14C analysis at a dedicated compact (4.5 x 6.0 m) system at energies below 1 MeV. In the last few years the facility was converted more and more to a multi-isotope system. Most isotopes now routinely measured at the TANDY (10Be, 26Al, biomedical 41Ca, 129I and actinides, e.g. 236U, Pu) benefit from the higher yield and better stability compared to larger facilities.
The Mini radioCarbon Dating System (MICADAS) was entirely designed and built at LIP in 2004 as a dedicated and optimized AMS system for radiocarbon measurements operating at 200 kV terminal voltage and with a footprint of only 2.3 x 3 m2. With the high yield and superior stability highest precision 14C measurements are possible. The ion source developed at LIP allows for measurement of solid (graphite) and gaseous (CO2) samples with various interfaces (e.g. elemental analyzer, HPLC, carbonate gas handling sources, laser ablation) providing the sample material.
