N2 - The design of the large-aperture variable-period undulator developed for the Novosibirsk free electron laser (FEL) is described. This undulator has a remarkably large (1.4) ratio of the aperture (inner diameter) to the minimum period. High amplitude of on-axis field is achieved due to the arc shape of the magnet blocks and poles of the undulator. Such large-aperture undulators can be used not only for long-wavelength FELs, but also as short-period undulators of modern storage-ring-based high-brightness X-ray sources and X-ray FELs. Results of computer modelling and calculated basic characteristics of the undulator are presented.
