    Abstract

    An un­aver­aged 3D model of the FEL has been de­vel­oped which can model vari­ably po­larised un­du­la­tors. The ra­di­a­tion field po­lar­i­sa­tion is self-con­sis­tent­ly driv­en by the elec­tron dy­nam­ics and is com­plete­ly vari­able. This paper de­scribes both phys­i­cal model and com­pu­ta­tion­al code.
