Phys. Rev. Lett. 61, 1713–1715 (1988)Synchrotron-Radiation Limit on the Focusing of Electron BeamsReceived 14 June 1988; published in the issue dated 10 October 1988 It is shown that there is an essential limit on the focusing of electron beams due to synchrotron radiation in the final focusing lens of a linear collider. The minimum possible beam size is determined almost only by an invariant emittance of a beam which is given at the entrance of a linear accelerator. © 1988 The American Physical Society URL:
