The quality assurance of particle therapy treatment is a fundamental issue that can be addressed by developing reliable monitoring techniques and indicators the plan correctness. Among available imaging techniques, positron emission tomography (PET) has long been investigated then clinically applied to proton carbon beams. In 2013, Innovative Solutions for Dosimetry in Hadrontherapy (INSIDE) collaboration proposed an innovative bimodal concept combines in-beam PET scanner with tracking...
Abstract High-energy, long gamma-ray bursts (GRBs) can be generated by the core collapse of massive stars at end their lives. When they happen in close-by universe exceptionally bright, as seen from Earth case recent, giant, long-lasting GRB221009A. GRB221009A was produced a collapsing star with redshift 0.152: this event observed many space experiments, which also detected an extraordinary afterglow. The large fluence prompt emission about 0.013 erg cm −2 illuminated geographical region...
Simultaneous PET/MR/EEG (Positron Emission Tomography - Magnetic Resonance Electroencephalography), a new tool for the investigation of neuronal networks in human brain, is presented here within framework European Union Project TRIMAGE. The trimodal, cost-effective imaging makes use cutting edge technology both PET and MR fields. A novel type magnet (1.5T, non-cryogenic) has been built together with scanner that most advanced photodetectors (i.e., SiPM matrices), scintillators matrices...
Abstract Time-dependent energy spectra of galactic cosmic rays (GCRs) carry crucial information regarding their origin and propagation throughout the interstellar environment. When observed at Earth, after traversing interplanetary medium, such are heavily affected by solar wind embedded magnetic field permeating inner sectors heliosphere. The activity Sun changes significantly over an 11 yr cycle—and so does effect on particles; this translates into a phenomenon called modulation. Moreover,...
The INSIDE project addresses the online dose monitoring in particle therapy issue.The proposed detectors exploit secondary neutral and charged particles emitted during treatment by irradiated volumes.The new detection techniques allow to return a measurement of released Bragg peak position.
Quality assessment of particle therapy treatments by means PET systems has been carried out since late `90 and it is one the most promising in-vivo non invasive monitoring techniques employed clinically. It can be performed with a diagnostic scanners installed outside treatment room (off-line monitoring) or inside (in-room monitoring). However efficient way integrating scanner delivery system (on-line so that biological wash patient repositioning errors are minimized. In this work we present...

Earth's atmosphere, whose ionization stability plays a fundamental role for the evolution and endurance of life, is exposed to effect cosmic explosions producing high energy Gamma-ray-bursts. Being able abruptly increase atmospheric ionization, they might deplete stratospheric ozone on global scale. During last decades, an average more than one Gamma-ray-burst per day were recorded. Nevertheless, measurable effects ionosphere rarely observed, in any case its bottom-side (from about 60 km up...
