摘要：

A hybrid (superconducting + soft iron poles and yoke) short model of a helical undulator was designed, built and successfully tested. The parameters of the model were chosen close to the requirements for free electron laser undulators: 10 mm diameter clear bore, 28 mm period, 0.95 T design field. The number of full periods is 6. A NbTi composite multifilamentary strip was used in the winding. During the tests the central magnetic field reached 1.065 T at 1215 A operating current. As far as we are aware, the combination obtained of bore-to-period ratio and magnetic field strength can be considered one of the best achieved practically for helical undulators.
