ABSTRACT:
An ion mirror for a time-of-flight mass spectrometer comprises a monopole electrode structure which operates at d.c. voltage. This electrode structure defines a field region in which an incident ion experiences an electrostatic reflecting force having a magnitude proportional to the separation of the ion from where it entered the field region or from where the ion exits the field region, if the latter separation is smaller. The ion occupies the field region for a time interval related to its mass but not its energy.
