The direct observation of high-energy cosmic rays, up to the PeV region, will depend on highly performing calorimeters, and the physics performance will be primarily determined by their geometrical acceptance and energy resolution.Thus, it is fundamental to optimize their geometrical design, granularity, and absorption depth,with respect to the total mass of the apparatus, probably the most...

Thick-GEMs (THGEMs) are robust gaseous multipliers, derived from the GEM design and introduced in the early 2000s. They are proposed for large-scale applications in several fields. THGEMs consist of Printed Circuit Boards (PCBs) with a regular pattern of holes obtained by drilling; they are manufactured in large series and large size. Mass production of THGEMs has already started in...

Directional DM search experiments face different challenges especially for the reconstruction of the recoil track and the detector scalability to very large masses while keeping the zero background level. The so-called neutrino floor, where the directionality becomes essential, requires at least a ton-scale detector. These masses are achievable by solid- or liquid-state detectors, but the...

Il progetto COSINUS (Cryogenic Observatory for SIgnatures seen in Next-generation Underground Searches) si propone di sviluppare calorimetri criogenici scintillanti per la ricerca di materia oscura, utilizzando ioduro di sodio (NaI) come assorbitore. Questo tipo di rivelatori permette di misurare simultaneamente la luce di scintillazione ed il segnale di calore indotti dall'interazione delle...

We present two techniques related to the production of rare isotopes and their consequent application fields. The first is related to the Darkside Experiment that makes use of liquid argon as sensible target for dark matter detection. In order to get an ultrapure and low radioactivity target, the argon will be purified in a 350 m tall distillation column placed in the Seruci mine in Sardinia...
