LABORATORI NAZIONALI DEL SUD
The Committee V of INFN recently funded the three-year project NEPTUNE (Nuclear process-driven Enhancement of Proton Therapy UNraVeled).
The project will start in 2019 with the main aim to study and understand the recently observed increase of protontherapy effectiveness for irradiations occurring in the presence of 11B atoms. A role in this effect should be played by the high-LET alpha particles mainly generated by the p(11B,alpha)2alpha channel, which has a cross section of the order of 1 barn at low energy. However, analytical calculations indicate that the number of alphas produced is too low to yield the observed biological effects.
