Figure 1
Plot of the relationship between the deflection parameter, K, and the undulator period, λ_u. The three negative sloped curves indicate combinations that result in undulator harmonics at 12.4 keV. The fifth harmonic at 12.4 keV was used to determine the choice of period. The four positive sloped curves represent the different technologies assuming a 6 mm magnet gap (CPMU and room-temperature IVU) and a corresponding 8 mm magnet gap for SCUs where a beam chamber is required. The two curves for the SCU represent the estimated fields for vertical and horizontal racetrack (VR/HR) configurations. The data point for the 15.6 mm period was from Bragin et al. (2018
