In radiocarbon applied research, both in Cultural Heritage and environmental contexts, minimising the invasiveness of the analysis is of fundamental importance. For this reason, at INFN-LABEC in Florence, the CHNet_Lilliput experiment aimed at reduci

The CERN PIXE-RFQ, a transportable proton accelerator for the machina project

Publikováno v: Nuclear Instruments and Methods in Physics Research Section B: Beam Interactions with Materials and Atoms. 459:153-157

CERN has been building a transportable RFQ for use in the examination of art masterpieces based mainly on the PIXE (Proton Induced X-ray Emission) technique with an extracted beam. This new PIXE-RFQ accelerator is very compact, only one meter in leng

Publikováno v: Nuclear Instruments and Methods in Physics Research Section A: Accelerators, Spectrometers, Detectors and Associated Equipment. 936:75-77

Many versatile applications in the life/earth science are based on the measurement of the radiocarbon. These applications are often limited by the minimum amount of carbon that can be measured in the sample: minimum size radiocarbon samples can be af

Publikováno v: Atmospheric Environment. 108:1-12

In this paper, a new way to apportion the absorption coefficient (babs) of carbonaceous atmospheric aerosols starting from a multi-wavelength optical analysis is shown. This methodology can disentangle and quantify the contribution to total absorptio
