Abstract

727,683. Discharge apparatus. BENDIX AVIATION CORPORATION. Aug. 12, 1952 [Oct. 2, 1951], No. 20291/52. Class 39 (1). A time-of-flight mass spectrometer having an ion-originating zone and an ion collector with means for indicating the relative times at which ions of different mass reach the latter, comprises means for creating between the zone and the collector successive regions, in a first one of which the ions are subjected to a first accelerating force, and in a second one of which the ions are subjected to a second and greater accelerating force, the relative extents of the regions and the position of the collector beyond the second region being so predetermined with respect to one another and to the values of the forces as to minimize the error resulting from statistical uncertainty on the initial conditions at the ionoriginating zone. As shown in the Figure, gas from a source 40 may be introduced into the space between a backing-plate 26 and a control grid 28 and there ionized by a beam of electrons emanating from a cathode 10. The ions are accelerated by applying pulses of, for example, 200 volts to plate 26 and 150 volts to grid 28, so that there are two acceleration zones, one between plate 36 and grid 28 and the other between grid 28 and grid 42; these zones are preferably of equal length. A collector plate 46 is arranged some distance away and is connected to a time indicator such as an oscilloscope. Specification 713,993 is referred to.
