The energy of the laser pulse is measured using an integrating sphere and a (GeGaAs) photodiode, integrated by a boxcar. To ensure that mass spectra and laser energies are recorded in pairs, a home built amplitude to time converter is used to write the energy as a time delay at the end of each mass spectrum. [Pg.63]

All TOF spectra are recorded with a 500-MHz digital oscilloscope (LeCroy) and averaged over several thousand laser shots. Boxcar averagers (Stanford Research) are used to integrate the signal of individual ion mass or electron eneigy peaks in the pump-probe experiments. The data are later corrected for laser fluctuations that are monitored by a photodiode. [Pg.53]

The SER of a PMT can also be recorded by splitting the signal and triggering the oscilloscope externally via a CFD. It is then possible to use a sampling oscilloscope or a fast boxcar device to record the pulse shape. There is, however, no reason why a normal TCSPC user should take such effort to record an SER pulse shape. [Pg.235]
