The double sided silicon strip detector (DSSSD) is a segmented commonly used in the fields of high energy physics and nuclear physics. This type for analysis reactions produced by charged particles. makes it well suited number analytical methods ion beam (IBA), such as Rutherford Backscattering (RBS) elastic recoil detection (ERDA). One was installed tested at Lund Ion Beam Analysis Facility (LIBAF) recently. modification to existing setup measure hydrogen concentrations depth profiles. When...
Particle Induced X‐ray Emission is a well‐established technique for quantitative elemental analysis down to trace levels. During microbeam analysis, where the beam collimated and focused into small spot, current reduces nA or less. The generation of characteristic X‐rays reduced in same proportion, leading long data‐acquisition times. This can partly be compensated by using detectors with large solid angle. In this work, performance an annular eight‐element silicon drift detector total angle...
Ion beam analysis has for decades been used as a tool geochemical of trace elements using both X-rays (particle induced X-ray emission) and nuclear reaction analysis. With the geoanalytical setup at Lund Beam Analysis Facility, boron content in geological samples with spatial resolution 1 µm is determined through In newly upgraded setup, single detector replaced by double sided silicon strip 2048 segments. After optimization, low µg g−1 can be measured.
A new setup for photon tagged nuclear reaction analysis pNRA is being developed at Lund's ion beam facility LIBAF. Particle induced gamma ray emission PIGE and NRA are two methods that have been extensively used light isotope measurement in IBA. There an abundance of reactions between elements MeV protons, deuterons alpha particles. This means principle all from lithium the way up to chlorine can be analyzed using those techniques. Detection limits improved some elements, if fused together...
Hydrogen normally occurs as hydroxyl ions related to defects at specific crystallographic sites in the structures, and is characterized by infrared spectroscopy (FTIR). For quantification purposes FTIR technique has proven be less precise since calibrations against independent methods are needed. analysis NMP can solve many of problems, due low detection limit, high lateral resolution, insignificant matrix effects possibility discriminate surface-adsorbed water. The been shown work both on...
Nominally Anhydrous Minerals (NAM) in the Earth's mantle contain trace amounts of hydrogen, as a result NAM's ability to incorporate hydroxyl ions. The isotopic composition these hydrogen reservoirs is for crust, well characterized. knowledge interior on other hand limited. It believed that isotopically heterogeneous and there may exist several characterized by different deuterium/hydrogen-ratios. Characterization can provide valuable information about mass transport during evolution planet....
Proton-induced reaction (p,α) is one type of nuclear analysis (NRA) suitable especially for light element quantification. In the case lithium quantification presented in this work, accelerated protons with an energy about 850 keV were used to induce 7Li(p,α)4He standard reference and geological samples such as tourmaline other Li-minerals. It shown that technique allowed measurement concentrations down below ppm. The possibility relate content boron a single was also demonstrated using...
Interest in high spatial resolution boron analyses from a geochemical perspective is related to the recognition of as an important tracer chemical recycling Earth, due solubility aqueous fluids and silicate melts. Although not nominal component common silicates they may still contain significant B-concentrations hence constitute reservoirs deeper parts Earth. Boron have been performed at Lund Ion Beam Analytical Facility for almost 20 years. For analysis nuclear reaction p+11B used with beam...

Over the past 10 years, several thousand otoliths have been analyzed with PIXE (using 2.55 MeV protons) at LIBAF (Lund Ionbeam Analysis Facility, formerly LNMP Lund Nuclear Micro Probe). 40 elements identified in otoliths, many levels suitable for analysis. Readily detectable starting Ca are: (the matrix), Ti, Cr, Mn, Fe, Co, Ni, Cu, Zn, As, Se, Br, Sr, Y, Zr, Mo, Cd, Sn (difficult), I, Ba (sometimes difficult), Pb (difficult). The detector system, used over this time period, is more...
