The present invention relates to a method of mass spectrometry, an apparatus adapted to perform the method and a mass spectrometer. More particularly, but not exclusively, the present invention relates to a method of mass spectrometry comprising the step of associating parent and fragmentation ions from a sample by measuring the parent and fragmentation ions from two or more different areas of the sample and identifying changes in the number of parent ions between the areas in the sample, and corresponding changes in the number of fragmentation ions between the two areas.

A high-energy ion implantation system has an ion source and mass analyzer to form and analyze an ion beam along a beam path. A first RF LINAC accelerates the ion beam to a first accelerator exit, and a second RF LINAC accelerates the ion beam to a second accelerator exit along the beam path. A first magnet between the first and second RF LINACs alters the beam path along a first plane. A third RF LINAC accelerates the ion beam, and a second magnet between the second and third RF LINACs alters the beam path along a second plane. A beam shaping apparatus defines a shape of the ion beam, and a third magnet between the third RF LINAC beam shaping apparatus alters the beam path along a third plane, where the first, second, and third planes are not coplanar.

A system for performing surface analysis on a material, includes a pulsed electron source that forms a monochromatic beam of incident electrons; means for conveying the incident electrons to the surface of a sample of material, so as to form backscattered electrons, and the backscattered electrons to detecting means, the conveying means comprising at least one electron optical system; means for detecting the backscattered electrons; the pulsed electron source comprising: a source of atoms; a continuous-wave laser beam configured to form a laser excitation zone able to excite the atoms to Rydberg states; a pulsed electric field on either side of the laser excitation zone, the pulsed electric field being configured to ionize at least the excited atoms and to form a monochromatic beam of electrons.

According to an embodiment, a plasma processing system is proposed. The plasma processing system includes a processing chamber for plasma; a two-chambered pumping block linked to the chamber through an orifice that creates a particle beam via a pressure difference, with the upper pressure regulated by a connected vacuum pump; a detector stage attached to the pumping block through another orifice and connectable to a vacuum pump to guide the beam through a third orifice; a mass spectrometer connected to the detector stage via the third orifice, featuring an ionizer that ionizes the beam's species by cycling through energy levels in multiple steps; and a shutter installed in the pumping block's path of the particle beam, designed to operate at each energy level step.
