Abstract
Bi-harmonic undulators are designed and field integrals are measured in a pulsed wire bench. An analytical formula is given for the shim counting and positioning along the length of the undulator. It is observed that the wire rigidity and stiffness of the thick wire do not affect the bi-harmonic undulator field measurement and gives comparable results with hall probe data.
