Outline of Final Research Achievements |
In this study, two electron beams with energy of 32 MeV, which are called as “double-decker electron beams”, were generated. Pulse radiolysis using terahertz (THz) probe pulses was developed based on the electron beams used as irradiation and probe sources. Transient decrease in transmittance of semiconductor (high-resistivity silicon) was observed in THz range when the electron beam induced quasi-free electrons in the semiconductor. Techniques of advanced spectroscopy for THz probe pulses emitted from electron beams were developed using a large-apertured photoconductive antenna with microstructured electrodes. Feasibilities of time-domain measurement of coherent transition radiation, which is emitted from a femtosecond electron beam, were indicated.
