    摘要: An ion source (10) for use in ion assisted deposition of films, has an ionisation region (13), a gas supply (22), supplying ionisable gas to the ionisation region, a gas excitation system (11, 12) causing ionisation of the gas, ion influencing means forming the ions into a current directed at a target, and an ion source controller controlling the ion source so as to intermittently produce the current.

    摘要: An ion gun (42) for producing a pulsed microfocused beam of ions comprises an ion source (1) arranged to produce a continuous ion beam along a z-axis toward a collector (13) having an aperture (14) on the axis. A deflector (7) is arranged to maintain the beam substantially stationary and incident on the aperture for a pulse time, to deflect the beam away from the aperture to the collector and subsequently to return the beam to be incident at the aperture. A focussing lens (15) focusses the beam from the deflection point (at 7) to a final image point, and a condensing lens (2) focusses the beam at the deflection point. A mass filter (6) selects a single ion species, and a second deflector (10) deflects the beam orthogonally to the deflector (7) so that the returning path of the beam on the collector (13) does not cross the aperture (14). A stigmator (60,61) and a beam scanner (19) are also provided.

    摘要: L'invention concerne une source d'ions.
    Cette source comprend une chambre d'ionisation (1) à gaz, une source d'électrons (SE,), des moyens pour faire osciller les électrons dans la chambre de manière à créer une zone d'ionisation (Z) du gaz. Elle est caractérisée en ce que les moyens pour faire osciller les électrons comprennent deux lentilles électroniques (L 1 , L 2 ) identiques dont les axes coïncident avec la direction d'oscillation, deux miroirs sphériques (M 1 , M 2 ) concaves tournés l'un vers l'autre et situés respectivement de part et d'autre des deux lentilles (L 1 , L 2 ) et dont leurs centres coïncident respectivement avec les foyers (F 1 , F 2 ) des lentilles, la source (SE 1 ) d'électrons étant située au foyer (F,) de l'une des deux lentilles (L 1 , L 2 ).
    Application à l'analyse des gaz par spectrométrie de masse.

    摘要: An ion source is disclosed wherein a sample is introduced into the sample chamber (1) of the ion source in the gas phase via a sample introduction capillary tube (2). The sample is directed onto a heated surface (6) coated with an oxidising reagent such as copper oxide. Carbon in the sample is oxidised to form carbon dioxide. The resulting carbon dioxide molecules are then ionised by electron impact ionisation with an electron beam (3) and the resulting ions are passed to a mass analyser for mass analysis.
