摘要: Abstract A radiochromic film, Gafchromic HD-V2, is applied to a possible method of measuring two-dimensional (2D) spatial profile MeV cluster ion beams. The coloration responses the HD-V2 film carbon and gold beams are experimentally investigated since some effect may appear. degree quantified as change in optical density (OD) by reading films with an image scanner for high-resolution measurement 2D beam profile. OD response characterized function atom fluence comparison. dependences on size, kinetic energy, species discussed. It found that sensitivity reduced when size large. delivered from tandem accelerator TIARA result using films. present results show use suitable detail ions, especially C 60 whose available intensity rather low comparison monatomic
