    Abstract: Ein Multireflexions-Flugzeitmassenspektrometer umfasst einen Massenanalysator mit einander gegenüberliegenden Spiegelelektroden und einer Fokalebenenkorrekturelektrode. Jede Spiegelelektrode ist im Allgemeinen entlang einer Driftrichtung verlängert. Die Fokalebenenkorrekturelektrode erstreckt sich entlang mindestens eines Abschnitts der Driftrichtung in dem oder angrenzend an den Raum zwischen den Spiegelelektroden. Ionen werden in die Spiegelelektroden injiziert und ein an der Spiegelelektroden bereitgestelltes elektrisches Potenzial reflektiert die Ionen im so entstehenden Ionenstrahl und bewirkt, dass die Ionen einem Zickzackweg folgen, während sie an den Spiegelelektroden entlang driften. An der Fokalebenenkorrekturelektrode wird ein elektrisches Potenzial bereitgestellt, um die Fokalebenenposition des Ionenstrahls so einzustellen, dass sie mit einer Detektoroberfläche eines am Ende des Ionenwegs platzierten Ionendetektors übereinstimmt.

    Abstract: A thermally conductive lamp reflector is provided that dissipates heat from a light source within the reflector. The reflector assembly includes a shell having a metallized layer on its surface. The shell is made from a composition including about 30% to about 80% by volume of a base polymer matrix and about 20% to about 70% by volume of a thermally conductive filler material. The reflector has a thermal conductivity of greater than 3 W/m° K and preferably greater than 22 W/m° K. The reflectors can be used in automotive headlamps, flashlights, and other lighting fixtures. A method of forming the lamp reflector is also provided.

    Abstract: 1534888 Discharge tubes INST VYSOKIKH TEMPERATUR AKAD NAUK SSR 21 Sept 1976 39048/76 Heading H1D A high energy charged particle beam-as described, an electron beam-is decelerated and collected by an arrangement of at least three electrodes of which the first encountered by the beam has a potential applied thereto substantially corresponding to the energy of the particle flow, the second is held at substantially zero potential and comprises a plurality of sharp members arranged to point towards the flow, and the third, upon which the particles may be collected, having a potential of the same sign as, but small compared with, that of the first electrode, whereby current flows of the order of 1000 amps. can be decelerated with very small accompanying secondary particle flows. The second electrode 11, Fig. 5, may be in the form of an array of needles 17 projecting from the body of the electrode through a corresponding array of apertures 18 in the third electrode 12. Alternatively, the second electrode may be provided with a parallel array (Figs. 6 and 7, not shown), or a crossed grid (Fig. 8, not shown), of knife edges projecting through corresponding arrays of slots in the electrode 12. In a modified, arrangement, Fig. 9, the electrode 12 1 is additionally provided with apertures 20 disposed between the projecting members 13, and giving access to collecting chambers 22. The array of sharp members, and subsequent electrode, may be arranged on concave spherical surfaces (Fig. 13, not shown). If the beam is magnetically focused, the deceleration is preferably provided with a magnetic field directed along the particle trajectories, as shown in Fig. 14, which includes an electromagnet 28, 30, 27, 29, the collecting chambers 22, Fig. 15, having needles of ferromagnetic material projecting thereinto to concentrate the magnetic field 32. A further embodiment (Fig. 16, not shown) generally similar to that of Fig. 9 includes an additional electrode (34), similar to and spaced downstream from electrode 12 1 , to improve focusing of the beam into the collector chambers, and to act as a suppressor electrode.
