The correct quantification of the dose released in charged particle therapy treatments requires the knowledge of the double differential fragmentation cross section of particles composing both beam and target. The FOOT experiment aims at measuring these cross sections for ions of interest for charged particle therapy applications. The paper describes the performance of the TOF-Wall detector of the experiment. The detector is composed of two layers of 44 cm x 2 cm x 3 mm plastic scintillator bars (20 for each layer), arranged orthogonally and read out by silicon photomultipliers.

In march 2019, the European Parliament has voted for a ban of single-use plastics to come into force by 2021 in all EU member states. Europe is setting new and ambitious standards, paving the way for the rest of the world. Dentistry aims to diminish its environmental footprint by adopting the 4R’s concept (reduce, reuse, recycle, rethink) and through the switch to eco-friendly home oral hygiene products.

An innovative approach, based on HyperSpectral Imaging (HSI), was developed in order to set up an efficient method to analyze marine microplastic litter. HSI was applied to samples collected by surface-trawling plankton nets from several parts of the world (i.e. Arctic, Mediterranean, South Atlantic and North Pacific). Reliable information on abundance, size, shape and polymer type for the whole ensemble of plastic particles in each sample was retrieved from single hyperspectral images.
