We present the studies carried out at the cyclotron facility at Thailand Institute of Nuclear Technology (TINT, Nakhon Nayok, Thailand). The cyclotron accelerates up to 30 MeV proton with a maximum beam current of 200 µA. Proton beam is transported to three target halls, including the R&D vault. Particularly, the R&D beamline consists of a five-port switching magnet allowing further extension for multidisciplinary research and experiments. The first station of the research vault is dedicated to non-destructive and multi-elemental analysis using proton-induced x-ray (PIXE) and proton-induced gamma (PIGE) techniques. For this purpose, the beam is extracted through an exit foil to the air. The beam size is then shaped by a set of collimators before reaching a sample. However, the range of the protons in air and the attenuation of x-rays may deteriorate. Therefore, the external irradiation system, including exit foil, collimator and detector arrangement, is evaluated in Geant4 to optimise the proton beam quality and improve detection efficiency. A detailed description of the simulation and results are discussed in this work.
