Synchrotron radiation from a curved plasma channel laser wakefield accelerator (1611.00560v1)
Published 2 Nov 2016 in physics.acc-ph and physics.plasm-ph
Abstract: A laser pulse guided in a curved plasma channel can excite wakefields that steer electrons along an arched trajectory. As the electrons are accelerated along the curved channel, they emit synchrotron radiation. We present simple analytical models and simulations examining laser pulse guiding, wakefield generation, electron steering, and synchrotron emission in curved plasma channels. For experimentally realizable parameters, a ~2 GeV electron emits 0.1 photons per cm with an average photon energy of multiple keV.
