(a) 0 V retardation. Electron TOF spectrum after Ne 1s ionization at 914 eV. TOF is 36.25 ns which corresponds to a kinetic energy of 44.2 eV according to equation (1) (red curve). (b) −480 V retardation. Electron TOF spectrum after N2 1s ionization at different photon energies. Peak center (black dots) fitted to equation (2) (red curve). Spectra are averaged over 100 pulses for higher statistics. |
