At the University of Liverpool we are developing free electron masers <100kV as a power source for industrial microwave applications. we required an undulator magnet design which was considerably less expensive than the designs normally used on optical wavelength free electron lasers. This paper describes techniques used to successfully construct low cost undulator magnets.
