| 内容記述 | The binary filter system to change beam properties was installed on the C-8 beam line in the general purpose exposure room of the NIRS-Cyclotron facility in order to alter beam properties. The plates in the binary filter system are made of poly (methyl methacrylate) (PMMA), which acts as a water-equivalent material. To evaluate the water-equivalent thicknesses of the PMMA plates, Bragg curves of an 80 MeV proton beam in a water phantom were measured with each PMMA plate or without any plates. The water-equivalent thicknesses of the filters were derived as displacements of Bragg peak with an accuracy of 10 micrometer. The mean ratio between real and water-equivalent thicknesses of the plates was calculated to be about 1.16. | |||||
