Frascati Via Enrico Fermi, 45 - 00044 Frascati (Roma) Italy The area of harmonic selection in undulator magnets is an important area of free electron laser (FEL) research. Within the undulator section of an FEL system, a wiggling electron beam emits coherent radiation at multiple wavelengths (harmonics), but in some cases the output should only be in the desired region for application purposes. Dispersion sections and unique undulators can be tailored in order to select harmonics and control their power levels. GINGER and PERSEO code were used for simulations. This research will lead to a better understanding of the emission process as well as the interaction of beam density distribution, the frequency and phase relationship of emission, and the amplitude of the emission as a function of time. Furthermore, harmonic control has applications within oscillator or amplifier-based FEL systems.

A description of the system configuration, estimated build-up schedule, and first experiments will be described.
