We study the use of a traveling wave waveguide as an undulator for short wavelength free-electron lasers (FELs) and synchrotron radiation sources. This type of undulator -which we will call TWU- can be useful when a short electron oscillation period and a large aperture for the propagation of the beam are needed. The availability
of high power X-band microwave sources, developed for the electron-positron linear collider, make it possible today to build TWUs of practical interest to produce short wavelength radiation from a beam of reduced energy respect to the case of more
conventional undulators. In this paper we will discuss the characteristic of the TWU, the systems that can be used to control the effect of RF power losses in the waveguide walls, and how to optimize a TWU and the associated electron transport system for use in a synchrotron radiation source or FEL.
