In this paper we study the spectral brightness of the radiation emitte
d by electrons moving in longitudinal wiggler and solenoidal magnetic
field. The analysis is based on the evaluation of the Lienard-Wiechert
potential retaining the condition of far-field limit. Some features o
f a longitudinal niggler are presented and compared with the results r
elevant to the brightness of the helical wiggler and the solenoidal ma
gnetic field employed in gyrotron-type devices.
