In Situ Observation of Proton-Induced DNA Fragmentation in the Bragg Peak: Evidence for a Protective Role of Water
R. Liénard, P. Barberet, K. Chatzipapas +5
We report in situ single-molecule measurements of proton-induced double-strand breaks (DSBs) in DNA immersed in water, using real-time fluorescence tracking along the entire proton…

Electric Fields in Liquid Water Irradiated with Protons at Ultrahigh Dose Rates
F. Gobet, P. Barberet, M. -H. Delville +8
We study the effects of irradiating water with 3 MeV protons at high doses by observing the motion of charged polystyrene beads outside the proton beam. By single-particle tracking…
