Description
M.Marafini The MONDO project (MOnitor for Neutron Dose in hadrOntherapy)
Particle therapy is a novel technique that uses charged particles for cancer treatment. Penetrating neutrons produce secondary particles higher in number with respect to photons and charged particles, allowing for a backtracking of the emission point not affected by multiple scattering. The technical challenges posed by a neutron detector aiming for high detection efficiency and good backtracking precision will be addressed within the MONDO project (MOnitor for Neutron Dose in hadrOntherapy) helping the improvement of Treatment Planning Systems software. The MONDO main goal is to develop a tracking detector capable of a full reconstruction and backtracking of secondary neutrons produced by the primary beam interaction with the patient body. The neutron tracker will measure the neutron production yields at different therapeutic beams at CNAO in Pavia.

The UTS project (Underwater Tracking System)
The aim of the UTS project (Underwater Tracking System) is to demonstrate the feasibility of an underwater tracking system, made of planes of solar cells, able to detect the light induced by ionizing particles in water. A charged particle traversing water leaves behind it a wake of excited molecule fragments (mainly H and/or OH) that will release a fraction of the primary energy loss as optical photons. Solar cells are widely available, cheap and are well suited to detect most of that electromagnetic radiation, with high internal quantum efficiency, in or near the visible range. The UTS objective is to verify that the claimed scintillation effect in water has the potential to be used and demonstrate that a device made of solar cells could efficiently measure this effect. If this feasibility study will produce positive results, it will be a step toward a Mton scale detector design.
