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%.

Academic Significance and Societal Importance of the Research Achievements

レーザーを使った誘電体加速器は、加速勾配が従来の高周波加速器の10倍の大きさであり、加速器を1/10の大きさにできるだけでなく、誘電体の微細構造からなる加速管の大きさは1/2ミクロン以下でありマイクロビーム発生が可能である。このような加速器は、1MeVの低エネルギーでは放射線生物学研究や放射線化学研究への応用が考えられ、高効率化・高繰り返し化を図る事によって素粒子物理への応用も可能になる。バイナリー回折格子の性質を利用して、本研究で得た微小光学共振器及び導波路型加速構造に関する成果は、小型の市販品レーザーでの電子加速に道を拓くものである。
