Notes:
A high-collection-efficiency fast-ion-beam photoelectron spectrometer is described. In a straight time-of-flight mode, the spectrometer collects ∼1% of the photoelectrons and achieves an energy resolution of ΔE/E of ∼5%. For coincidence experiments requiring greater collection efficiency, a paraboloidal electrostatic mirror is used. The mirror collects ∼40% of the photoelectrons while maintaining ΔE/E≤35%. In both modes of operation, a time- and position-sensitive electron detector allows conversion of the photoelectron laboratory energy to center-of-mass energy. The fast-ion-beam photoelectron spectrometer is used to prepare mass- and energy-selected neutral molecules which are used in molecular dissociation studies. © 1995 American Institute of Physics.
