    "abstract": "It is shown in an electron-beam-plasma system that phase-space holes evolve\ndynamically in electron time scales from appearance to collapse. The holes are\nsynchronized with a wave packet dominated by a beam mode, and their velocity\nradii depend on the packet crest amplitudes. This suggests that the holes are\ninduced by a self-trapping phenomenon. It seems from the observed images that\nthe trapped-beam is hard to be detrapped while the packet grows linearly, but\neasy to be done after that.",
