The successful utilization of an ion channel in a plasma to wiggle a 28.5 GeV electron beam to obtain broad band X-ray radiation is reported. The ion channel is induced by the electron bunch as it propagates through an under-dense 1.4 meter long lithium plasma. The quadratic density dependence of the spontaneously emitted betatron X-ray radiation and the divergence angle of (1 {approx} 3) x 10{sup -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 1.42 KeV photon energy are estimated.
