Phys. Rev. E 75, 057401 (2007) [4 pages]Radiation emission by extreme relativistic electrons and pair production by hard photons in a strong plasma wakefieldReceived 3 November 2006; published 14 May 2007 The radiation spectrum of extreme relativistic electrons and the probability of electron-positron pair production by energetic photons in a strong plasma wakefield are derived in the framework of a semiclassical approach. It is shown that the radiation losses of a relativistic electron in the plasma wakefield scale proportionally to ε2∕3 in the quantum limit when the energy of the radiated photon becomes close to the electron energy ε. The quantum effects will play a key role in future plasma-based accelerators operating at ultrahigh electron energy. © 2007 The American Physical Society URL:
