Electric charge tubes _for especially F recording tube

The innovation relates to an electrical discharge tube with at least one completely or partially insulating surface on which relatively slow electrodes collide and one of these electrons on the outer surface of the oven is hardened. This applies in particular to image display tubes working with low electron sclxwiDtdigiceiten "like κ · Β" in the image orthicon and in the vidicon.

In the case of such holes, voltage images are generated on insulating surfaces or semiconductors in accordance with the subject area, which is projected onto an area opposite these surfaces. These tension images * which cause the tone of the τοη aen biotoelectrons · * result from secondary emission or, in the case of "idikos", are created by the EhotiOleituBg of a semiconductor. ? scanned by one half of slow electrons, with so many electrons hitting the positive points that they are discharged * under slow electrons are electrons of so low energy with parts that the secondary emission coefficient of the 3? r surface

If the plate 5 is scanned by the electron beam 9, the return will return and the beam will be modulated, so that when the potential Mldes on the plate 5 is scanned, fluctuating quantities of electrons are taken from the various charged points on the surface of the plate 5 from the beam current It is therefore important here that sleictrons, even as most of them have hit the surface of the plate 5, which do not again allow flexion, it is evident that the separate conductive particles of layer 7 according to the flow have approximately the same low flexion coefficient for such electrons like a cohesive layer of material j. But they do not need a permissible increase in conductivity so that the surface of the leaf 3 remains sufficiently insulating.
