Figure 4
Time dependence of transient spectral changes at 709 eV measured by three different detection modes, with exponential fit and residual. The spectra are stacked vertically for easier comparison. A constant pre-time-zero offset was subtracted and the transient change normalized to unity for easier comparison. All spectra were acquired in sequence and using the same laser power and fluence. Analysis shows that noise is reduced by a factor of up to four using PSB-KAC. |
