Energy and profile of the proton beam of the IBA Cyclone 18/9

Abstract

The characteristics of the proton beam produced by the IBA Cyclone 18/9 medical cyclotron were investigated, focusing on its energy and profile. The proton beam energy was measured as 18.25±0.25 MeV using activation foil detectors. The beam profile was characterized using the Timepix3 based detector, revealing a Gaussian distribution with consistent widths and slight asymmetry in the horizontal plane. This study presents a straightforward methodology for evaluating cyclotron beam parameters using activation foils and pixel detectors, providing a tool for optimizing target design and expanding the applications of medical cyclotrons beyond radiopharmaceutical production.
