implantation of electrons in the glass

The objective of our work is to study the behavior of the glass subject to electronic bombing.In the context of this work we first studied theoretically the establishment of electrons in a material in this case the glass. This last which has become a powerful technique to synthesize nanoparticles buried in a material,We postpone the penetration of the electrons according to their acceleration and the density of the material, then we establish the electric field within the material according to the fluence, we thus refer the conditions of destruction of the materialWe highlight that glass can reach a certain load allowing it to destroy it. The value of the disruptive field is between [0.5 to 1.5 mv cm-1]In a second step we are interested in the realization of an electron cannon in order to provide a bundle of focused and energy electrons, more precisely we discuss on this basis the practical design of the latter made up of three important elements a filament of Tungsten, Wehnelt cylinder and anode.In this instrument the electrons are accelerated under high tension a few thousand volts up to 1 MEV. We postpone in this work the thermogal current as a function of the tension, and we discuss the assembly chosen.
