Title: Current two beams piecewise undulator

Abstract: A new undulator structure for free electron lasers was presented. Current PIECEWISE devices produce magnetic fields which are spatially periodic. The current has alternating directions in wires stacks. The Biot - Savart law was analytically evaluated. The structure versatility cover longitudinal undulator or wiggler design for one or two beams devices with transverse momenta.

Key words: Free electron laser, Electromagnetic undulator
