Figure 17
Periods of the undulator recovered by analysing the reference and measured magnetic fields of the simulation presented in Fig. 15. The measured magnetic field has been artificially shifted down by 20 µm for a better visualization of the component of the component F(p) of the systematic error. The refill of the helium during the measurement generates a systematic error starting from the 15th peak analysed. The corrected data are also plot. These curves are obtained considering dHP,err = 0 µm. |
