The polarisation of synchrotron radiation is sensitive to the motion of the electrons within the electron beam source. This motior has been incorporated into a complete description of the beam polarisation, based on evaluation of the polarisation density matrix. Calculation of the degrees of linear and circular polarisation shows the importance of taking account of the electron beam characteristics. A solution for the degree of linear polarisation on the electron beam orbit using a series expansion is presented and is shown to agree with the same parameter calculated numerically.
