(i) Spectral intensity of the (a) spectrometer (with turn 2 × 100) and (b) bolometer, calculated for EL = 0.4 mJ and gap = 17 mm. (ii) Spectrometer and (iii) bolometer maximum intensity and frequency of maximum intensity versus wiggler gap calculated for EL = 0.4 mJ and versus EL for gap = 17 mm. In all plots, red lines or dots represent the first, blue the second and green for the third turn. In (ii-a) and (ii-b), second-turn intensity × 100. In (iii-a) and (iii-b), black triangles represent the ratio first over second-turn form factor maximum intensities. ZR = 0.35 m and = 35 fs FWHM. |
