Figure 4
Experimental photoelectron spectra (black circles) for various storage time windows starting from 0.1 to 3 s. The green dotted lines are the fitted photodetachment electron spectrum model distributions. The solutions of the Master equation (Eq. 3) are shown by the red solid lines. The shaded vertical rectangles indicate the initial location of the peak for the first time window (upper left panel). Due to the beam lifetime the number of ions left in the trap is decreased, therefore resulting in a lower signal to noise, as reflected in the later trapping time windows.
