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.
Keywords
