18. A general explanation of time-correlated photon counting can be found in, for instance, the Stanford Research Systems instrument catalog (application notes). In our application of the technique we work in a photon counting regime (∼0.1 detected photons per laser shot) and proceed as follows: (i) a signal from the microchannel plate detector is sent to a constant fraction discriminator (CFD) (ORTEC model 934) and (ii) the signal from the CFD is sent to a time-to-amplitude converter (TAC) (ORTEC model 566). A (laser) photodiode signal triggers the TAC, which now waits for a signal from the CFD. When this signal is received (a photon is detected), the TAC outputs a voltage to indicate the time delay between the laser trigger and the detected photon. A personal computer reads the TAC voltage on every laser shot to determine if (and when) a photon was detected. As indicated in the text, frequency-doubled laser pulses (∼100 fs) were used to determine the time resolution of the apparatus; we also note that the same laser pulses determine time zero for the experiment.
19. We calculate that the spectral response of the detection apparatus varies by ∼15% between 55 and 120 eV. Three factors are included in the calculation. First, the wavelength-dependent reflectivity of gold (a collection optic and a gold-coated diffraction gratings) is calculated using a commercial software package (XCAL, Oxford Research Group). Second, the wavelength-dependent efficiency of a balzed diffraction grating is calculated [see, for instance, Anne P. Thorpe, Spectrosphysics (Chapman and Hall, London, 1988)]. Finally, the detection efficiency of the microchannel plate detector is taken from experimental data [O. H. W. Siegmund (unpublished)].
