The heavy ion collision is an environment where gluon saturation can be achieved and probably forming a gluon dominated region "the Glasma''. The gluons forms a semi-classical background that can be approximated by a uniform field. Partons escaping the collision and moving across the high density gluon region is behaving in a way similar to synchrotron radiation. We present a geneneralisation of QED synchrotron radiation to the QCD case with a chromo-magnetic field using the Schwinger's source method. It is shown that the QED case can be obtained as a special limit.
