碩士 === 國立交通大學 === 應用化學系碩博士班 === 104 === In order to use two light source with different wavelength and energy range: soft X-ray from synchrotron light source and vacuum ultraviolet laser. We designed the tunable voltage divider and movable detector to fit two light source in different wavelength and energy range. First, we modified the structure of the Jet Dump system. With this changes, we can enhance the performance of vacuum system. In addition, we make a discussion with the data acquisition system. We can overcome the dead time problem of detection with Hex-DLD. And we also change the signal logic unit to match the trigger timing both of the laser system and synchrotron radiation which is running under the multi-bunch mode. Then build the relationship between laser, electron and ion in time domain.
