| Outline of Final Research Achievements |
We designed and developed a high spatially resolved imaging spectroscopy system combining a microscope and an imaging spectrometer in order to observe the propagation of intense laser pulses and electron injection(wave breaking). We constructed this system and performed sensitivity calibration of spectrometer, but we could not reach imaging spectroscopy of self emission and scattered light from laser plasma, so we will set it as future task. On the other hand, we improved the energy measuring instrument of electrons necessary for investigating the correlation between the position of electron injection point and electron energy, and established a method that can measure energy accurately for pointing unstable electron beams. We successfully observed the 0.6 GeV monoenergetic electron beam using this measurement method.
