Abstract

Theoretical and experimental studies of novel free-electron laser (FEL) schemes with 2-D Bragg resonators of planar and coaxial geometry are discussed. The highly selective properties of 2-D Bragg resonators are described including comparison with results of "cold" microwave measurements. First results of experimental studies of a planar W-band FEL based on the accelerator ELMI (INP RAS) are presented. Progress in a coaxial Ka-band FEL experiment under construction at the University of Strathclyde is described. A new project at the Budker Institute investigating a multibeam FEL where 2-D distributed feedback is used to synchronise several FEL units of planar geometry is also discussed.
