    Abstract: A multiple charged-particle detector system includes a plurality of charged-particle detector assemblies (10-12) which are each made up of a first arm (19-22) and a second arm (24-27) extending at an angle to each other. Charged particles (4-7) enter an aperture (14-18) at the entrance of the first arm (19-22) of each detector assembly (10-12) and strike a dynode (30-33) positioned at the intersection of the two arms causing electrons to be emitted by the dynode (30-33). Some of the electrons pass into the second arms (24-27) of the detector assemblies (10-12) and are detected by a continuous-dynode electron multiplier (35-38). The first arms (19-22) are narrower than the detectors (35-38), and the detector assemblies (10-12) are arranged in such a way that the minimum separation at which charged-particle beams (4-7) can be detected is determined by the widths of the said first arms (19-22) of the detector assemblies (10-12), and not by the widths of the detectors (35-38) themselves.

    Abstract: The disclosure relates to a system for implanting ions into a target element including a source arrangement (230) for producing an ion beam; a beam analyzing arrangent for receiving the ion beam and selectively separating various ion species in the beam on the basis of mass to produce an analyzed beam; and a beam resolving arrangent disposed in the path of the analyzed beam for permitting a preselected ion species to pass to the target element. The ion source arrangement (230) comprises an arc chamber (230C) having an elongate exit aperture (232), and an elongate filament-cathode (230D). Bias and operating potentials are provided for the source arrangement and gaseous material to be ionized is supplied to the chamber. The ion source (230) utilises an electromagnet arrangement (280) having poles (281) aligned with the source filament (230D) for causing the electrons emitted by the filament to spiral around and create ions of the gaseous material supplied to the chamber (230C) and to compensate for non-uniformity in the ion beam emitted along the chamber, current to the field coils of the magnet for each pole is controlled independently.

    Abstract: There is disclosed a high speed pulse train generator for generating a train of pulses having arbitrarily close spacing. The apparatus in one form consists of a generator loop (82), comprising a fiber optic waveguide looped through a directional coupler (86), with the output fiber (76) serving as the input fiber for a similarly structured multiplexer loop (84). The lengths of the two loops (82, 84) are adjusted such that the time difference (τ) in the propagation times of light around the respective loops (82, 84) is small compared to the time of propagation around either loop (T, T- T ). The times are adjusted to obtain any arbitrary spacing of the pulses in the output pulse train (A. B. C, D, E) which comprises interleaved pulse trains resulting from each pulse input (92, 100) to the multiplexer loop (84).
    Also disclosed is a single loop embodiment for bidirectional data rate transformation and methods of using all the embodiments.
