Abstract: | The in-air beamline at the microanalytical center of the Jo?ef Stefan Institute in Slovenia has recently been upgraded with a wire-mesh current-integration normalization device and a RBS detector in helium flush. For positioning of the targets, the laser-triangulation with 40 μm repeatability was realized using 100 μm wide laser beam and a static camera. Metal plated historical objects were investigated for their gilded and tinned surfaces. Artificial samples were produced by dip-tinning and compared with archaeological samples. A surface roughness was found to be an important parameter for fitting the spectra by the SIMNRA software. |
