Abstract
A comparison between three possible cavity configurations, the confoca l cavity, the ring cavity and the Bragg cavity is presented for a mill imeter FEL set within the high voltage head of an electrostatic accele rator. A simple mechnical design to make the Bragg cavity tunable is p roposed. The usual theory of the sinusoidal Bragg corrugation, in cyli ndrical geometry, is extended to the rectangular corrugation and, furt her, the theory of the Bragg mirror is extended to rectangular geometr y. The features of a Bragg mirror in cylindrical and rectangular geome try are compared.
