We present the development of a novel detection system specifically engineered for the characterization and detection of diluted ion beams with fluxes below 10³ particles/s and down to the single charged particle. Furthermore, the device is designed to provide sub-micrometer spatial resolution while ensuring minimal disturbance to the ion beam, a feature crucial for applications requiring...
The CYGNO collaboration is developing a gaseous Time Projection Chamber (TPC) with optical readout, optimized for low-energy nuclear and electronic recoil detection. The detector concept exploits electroluminescence generated during charge multiplication in a triple-GEM stack, which is simultaneously imaged by Active Pixel Sensors based on scientific CMOS technology (≳4 Mpix) and recorded by...
Abstract Recent advancements in low-energy rare-event searches rely on cryogenic calorimeters, which provide a low-noise environment crucial for the direct detection of dark matter and neutrinos. A key challenge in these detectors is accurately characterizing their response within the region of interest (ROI), typically spanning from O(10 eV) to O(1 keV). Conventional radioactive sources used...
In particle therapy, interactions of primary particles with tissue produce secondary neutrons that contribute to the out-of-field dose and increase long-term cancer risks in the patient. In space radiation, galactic cosmic rays interacting with spacecraft walls also generate neutrons, which represent a significant fraction of astronaut exposure. In both scenarios, neutron spectra by...
Silicon microstrip (Si-µstrip) sensors are employed in most of current space detector tracking systems for charged cosmic-rays, such as the DAMPE satellite detector or the AMS-02 detector onboard the ISS. As they allow for large-area coverage with contained electronic channels and power consumptions, they are ideal sensors for high-energy physics applications in space-borne instrumentation,...
