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...
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....
This paper describes the fabrication and initial characterization of an ultra-thin silicon PIN detector using a new technique in nanotechnology. In collaboration with Nuclear Physics Division Lund Nano Lab at University, we have developed manufactured ultra thin Δ <i xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">E</i> -detectors for spectroscopic applications. The process has been carried out double-polished substrate n-type wafer locally thinning...
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...
This paper describes the fabrication of efficient ultra-thin silicon transmission detectors for use as pre-cell in single-ion experiments on living cells at Lund Ion Beam Analysis Facility. More than 40 different thicknesses down to 5 μm have been fabricated and packaged. The main design considerations were very low leakage current (below 9 nA) full depletion voltage biases less 0.5 V room temperature. In addition, we shown that cooling device can reduce 3 nA. experimental testing detection...
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...
The study aim determine the energy response of nuclear track detector cellulose nitrate CN-85 with thickness (100µm) for alpha particles emanated from Americium source 241Am (1µCi) at irradiation time (5 min). process irradiated detectors has been done by using etchant (NaOH) normality (5N) and etching temperature (50°C) different times(0.5-4.5hr). results led to spectrum which responded range (0.2-4.5 MeV). It also found that there was an increment in average radii tracks Etching all used...

In this work, a simple method for producing Perovskite solar cells [PSCs] by recycling automobile batteries is used. Trying to get rid of some structures or materials which are harm the environment (i.e. recycled car batteries) using lead [Pb] sheets from those battery. Also, reusing we will avoid disposal toxic battery elements and provide an alternative technique, readily-available Pb source fabricating PSCs. were prepared two-step spin coating solution grown on FTO glass substrate.
