Phys. Rev. Lett. 64, 1231–1234 (1990)Plasma-based adiabatic focuserReceived 30 October 1989; published in the issue dated 12 March 1990 Theoretical analysis is made of an intense relativistic electron beam moving through a plasma of increasing density, but density always less than that of the beam (underdense). Analysis is made of the beam radiation energy loss and it is noted that the focuser is insensitive to the beam energy spread due to radiation loss. Furthermore, because of the scaling behavior in the nonclassical regimes, the radiation limit on lenses (the Oide limit) can be exceeded. © 1990 The American Physical Society URL:
