Mean value and standard deviation (FWHM) of the central wavelengths calculated for each FEL pulse number for 1000 consecutive pulse trains. (a) A linear slope with increasing setpoints has been applied to the RF amplitude; (b) constant setpoint for the RF amplitude; (c) a linear slope with decreasing setpoints has been applied to the RF amplitude. |
