| Research Abstract |
A pulseradiolysis experiment was done with 28L and 18L mode. In order to compress an electron pulse with twin mode, we adjust a length of a wave guide of 28L.We then compressed the electron pulse to 2 ps. While we got the Cherenkov light as long as we could. Insufficient electron charges for the pulseradiolysis experiment was generated, however.
An x-ray diffraction experiment using picosecond x-ray pulses was done with 28L mode by irradiating picoseconds electron pulses to Cu target. We then got diffraction images of NaCl crystal. This experiment was performed for a new femtosecond time-resolved dynamic microspectroscopy which was named by us as "the pulse-snapshot method". Next we constructed the synchronization system of subpicosecond electron pulses with femtosecond laser pulses which is indispensable to the new method, and then the timing-jitter of the system was 3.7 ps at the standard deviation.
Furthermore we constructed the Michelson interferometer for femtosecond electron pulses and tried to estimate the possibility of the interferometer which will be used for next bunch compression system. And then The possibility could be estimated quantitatively.
