With the objective of carrying out an Inverse Free Electron Laser (IFE
L) electron accelerator experiment, an iron dominated (Vanadium Perman
dur) fast excitation, laminated (variable period length) planar wiggle
r, making use of copper field reflectors, has been constructed and has
been measured in several period length tapering configurations. This
report presents an analysis and experimental results of this wiggler,
typically of which the parameters are lambda(w) = 3.7 cm, B(max) = 1.8
