| Outline of Final Research Achievements |
In order to develop an on-chip dielectric accelerator and utilize it for the radiobiology research as well as the radiochemistry, we performed the theoretical study to determine the optimum configuration of the dielectric accelerator based on the binary-blazed dielectric grating (BBDG) theory. Besides the simple BBDG configuration, an optical micro resonator (OMR) and the waveguide (WG) type structure were studied for improving the energy conversion efficiency from the light to the electrons. The simulation showed that the OMR structure enable to reduce the required laser energy to 0.76% of the BBDG configuration. The energy conversion efficiency of the WG configuration is improved to 10%.
