    Abstract: A technique for providing a grid for a gate such as utilized in gating a stream of ions or other particles in a spectrometer instrument. The grid of wires may, for example, be a so-called Bradbury-Nielson Gate that consists of a set of two electrically isolated sets of equally spaced wires that lie substantially in the same plane and alternate in potential. The method utilized to provide is to first fabricate a frame of an insulating substrate having a hole and depositing metal film patterns such that conductive portions are formed on either side of the hole. Conductive portions on either side form a series of terminating pads on the portion of the substrate closest to the hole and a bus bar. Grid wires are then formed by stretching a section of wire with desired constant tension across the hole and bonding the ends of the wire to a respective one of the pads on one side and bus bar on the other side. The method provides a rapid, inexpensive way to fabricate such modulating devices.

    Abstract: There is disclosed a time-of-flight ion-scattering spectrometer which comprises an ultra-high vacuum chamber sized to accommodate a flight path of sufficient length to provide unit mass resolution at all detection positions and which has means for detecting both ions and neutral particles at both continuously variable forward scattering and backscattering angles. Spectra of both neutrals plus ions as well as neutrals only can be obtained in the same experiment. The polar incidence angle, surface azimuthal angle, and scattering (or recoil) angle can all be varied continuously and independently of one another. The associated method, Scattering and Recoiling for Electron Distributions and Structure (SREDS), allows one to determine atomic structure of substrate surfaces, the structure of adsorbate sites, and electron distributions above surfaces. Even light adsorbates such as hydrogen, carbon, and oxygen can be quantitated by this method.

    Abstract: An apparatus for separating charged particles according to their respective energies. The charged particles are decelerated and passed through a long cylindrical electrode having a focusing coil. Since the velocity of the particles differs according to their respective energies, the particles are separated in the electrode and exit the electrode at different times.
