Abstract: The inventive mass spectrometer operates with an inhomogeneous oscillatory electric field and operates with the continuous injection of charged particles into the electric field. Particles of all species are acted upon by the field, and some of the species ultimately are detected to produce an output which is random with respect to the phase of the oscillatory field. Appropriate parameters of the electric field are varied so that ions of some species bunch up and produce output pulses which are above the random output caused by the detection of the other species which do not bunch. Detection of these pulses and their relationship to the phase of oscillation of the electric field uniquely identifies the bunched species in accordance with the mass-to-charge ratio. Different species can be identified by properly readjusting the electric field parameters to cause bunching of the different species.

Abstract: An ion source device that includes apparatus for pulse injecting ions into a field-free drift region where those ions separate according to their velocities or kinetic energies. A cyclically varying electric field is established at the end of the fieldfree drift region. Each charged particle enters the electric field at a time determined by its velocity and interacts with the field in a manner dependent upon the phase of the field upon receipt of that particle. The cyclically varying electric field decreases the velocity distribution for particles received during the first half of a cycle, and increases the distribution for particles received during the second half of a cycle. Mass analyzing apparatus is disposed to receive and measure the concentrations of species of charged particles expelled from the cyclically varying field. The output provided by the mass analyzing apparatus also facilitates variation of the cyclically varying electric field to provide a particular species with a desired velocity or kinetic energy distribution.

Abstract: A mass dependent ion microscope having an array of very small mass filters, interposed between the source of an ion image and an image transducer for transmitting on a point-for-point basis only ions of a predetermined mass-to-charge ratio, is described. The point-for-point transmission by the mass filter array preserves the image information of the original ion image and permits the filtered ion image to be visually observed on a phosphor screen or otherwise detected. The individual filter elements of the array may be either of the monopole or quadrupole structure fabricated from glass.
