A magnetic-bottle-type electron spectrometer is combined with a fs-laser system to perform time-resolved photoelectron spectroscopy of a liquid jet. The spectrometer is optimized for electrons with low kinetic energies. Currently, the collection efficiency is about 10%, the resolving power at 2 eV is about 15. The experimental technique is described in detail, and the results of first experiments with aqueous solutions of sodium iodide of different concentrations are discussed. This experimental approach opens up exciting new perspectives to study photochemical and photophysical reactions of biologically and chemically relevant substances in liquid environments.
