Phys. Rev. Lett. 88, 135004 (2002) [4 pages]X-Ray Emission from Betatron Motion in a Plasma WigglerReceived 8 October 2001; published 19 March 2002 The successful utilization of an ion channel in a plasma to wiggle a 28.5-GeV electron beam to obtain broadband x-ray radiation is reported. The ion channel is induced by the electron bunch as it propagates through an underdense 1.4-meter-long lithium plasma. The quadratic density dependence of the spontaneously emitted betatron x-ray radiation and the divergence angle of ∼(1–3)×10-4 radian of the forward-emitted x-rays as a consequence of betatron motion in the ion channel are in good agreement with theory. The absolute photon yield and the peak spectral brightness at 14.2-keV photon energy are estimated. © 2002 The American Physical Society URL:
