ID (Undulator and Wiggler) Radiation Power Calculator
Power density calculations are performed for an undulator or wiggler using equations presented by Kim (
K. J. Kim, "Angular Distribution of Undulator Power for an Arbitrary Deflection Parameter K,"
Nuc. Instr. and Meth. A246, pp. 67-70 (1986)). The equations can also be found in this
Relevant functions are obtained by numerical (Simpson) integration. Power densities are also calculated
at selected points (nodes in the Finite Element Analysis terminology). Coordinates for the points can
be entered manually,or pasted in the left textarea below.
For highly precise and complex power calculations, specialized codes (see for instance, XOP) are recommended.
