New undulator for the first stage of Novosibirsk free electron laser (FEL) was developed. Installation of the new undulator will significantly increase radiation tuning range of the first stage FEL due to its features, among them are possibility to vary period of the undulator continuously, possibility to change number of periods and small period to aperture ratio. Mechanical construction is described and some magnetic field simulation results are presented in the article.
