  • Method of trapping accelerating electrons in plasma
    Patent number: 7049736
    Abstract: Background plasma electrons in a laser wake field are trapped and accelerated using a sharp downward density transition. A short and intense laser pulse travels through low density plasma with a sharp downward density transition. The density transition scale length is much smaller than the wavelength of a laser wake wave. As the laser wake wave passes the density transition, its wavelength increases suddenly so that some background plasma electrons are self-injected into the acceleration phase of the wake field and trapped and accelerated by the strong laser wake field.
    Type: Grant
    Filed: February 12, 2003
    Date of Patent: May 23, 2006
    Assignee: Korea Electrotechnology Research Institute
    Inventors: Hy-yong Suk, Guang-Hoon Kim, Jong-Uk Kim, Chang-Bum Kim, Hae-June Lee
