Abstract
A velocity-map imaging system for time-resolved photoelectron spectroscopy is presented and discussed. Nanosecond gating of microchannel plates synchronized with the excitation laser in a velocity-map imaging spectrometer has been used to generate time-resolved images of electrons emitted from photoexcited xenon atoms and small carbon cluster anions. These images represent a time slice in the kinetic energy spectrum and reveal the differing time scales of competing electron emission processes.
