	Funding: ISTC We calculate the spectral distribution of spontaneous emission and the gain of electrons moving in plane wiggler with inhomogeneous magnetic field. We show that electrons do complicated motion consisting of slow(strophotron) and fast(undulator) parts. We average the equations of motion over fast undulator part and obtain equations for connected motion. It is shown, that the account of inhomogenity of the magnetic field leads to appearence of additional peaks in the spectral distribution of spontaneous radiation and the gain.

	C.W. Ostenfeld, M. Pedersen Danfysik A/S, Taastrup, Denmark
	Danfysik has designed and built a 300 mm fixed-gap electromagnetic wiggler for the ELBE radiation source at Helmholz Zentrum Dresden Rossendorff. This wiggler will serve as a source of narrow-band THz radiation in the 100 μm to 10 mm range. Due to careful magnetic modelling, and an effective shimming process, we were able to deliver magnetic performance at a high level. We present the details of the modelling, as well as magnetic results.
