Computer simulation of the optical system with cylindrical lenses for modified ignition coordinate gauge
The paper introduces optical system for modified ignition coordinates of two-dimensional gauge. The analysis of the optical system was carried out by computer simulation.
Detection time of the explosion initial stage by the electro-optical system with cylindrical lenses
The arcticle is devoted to the experimental investigations of the electro-optical system (EOS) with cylindrical lenses. It was proved the efficiency of the system and defines the detection time of the explosion initial stage.
Influence of electric fields on friction electrification between metals and borosilicate glass
Abstract In a cylindrical geometry, electric fields were applied through the entire contact area between the sliding metal and the glass surface. The maximum electric charges developed on the metal were measured and plotted against the applied voltage producing the field. The metals were high-purity nickel and gold. The borosilicate glass was Pyrex, brand 7740. The experiments with nickel, which has a work function greater than that of the glass, were performed in 10 −7 mm Hg vacuum. The experiments with gold, with a work function smaller than that of glass, were carried out in air at atmospheric pressure. The results show that: 1. 1) There is both asymmetry and a reversed slope portion in the charge vs. voltage plot. 2. 2) For a certain range of reversing fields, the electric charge developed on the nickel is always negative and the charge on gold is always positive.
