| 内容記述 | Although light emission from an acrylic block during irradiations of carbon-ions lower energy than the Cerenkov-light threshold was found recently, the origins and fractions of the light in the images were not yet obvious. Since light spectra may provide information to estimate the origins and fractions of the light emission, we conducted the optical imaging of acrylic block during irradiations of carbon-ions using charge coupled device (CCD) camera with optical filters. We measured the light images of acrylic block with optical filters of different wavelengths using an ultraviolet (UV) sensitive CCD camera during carbon-ion irradiations with the energy slightly higher energy to produce secondary electrons to emit Cerenkov-light (241-MeV/u). From the images, we derived the depth profiles with different wavelengths and calculated the spectra of the emitted light from acrylic block. The depth profiles showed higher intensity due to Cerenkov-light at the shallow area distributed in the images of longer wavelengths. By the calculations between depth profiles of different wavelengths, we could derive the depth profiles for possible origins of the produced light: luminescence, Cerenkov light and scintillation of acrylic block. Using the derived fractions of these components, we could estimate the depth profiles of these three components with different wavelengths. | |||||
