Abstract

A method for measuring the intensity of focused high-power laser pulses based on numerical simulation of high-harmonic generation in the laser peeler regime is proposed. The dependence of the efficiency of high-harmonic generation on the laser pulse intensity and the spatial parameters during interaction with solid targets is studied numerically. The simulation clearly shows that the amplitude of the generated harmonics depends on the laser pulse parameters. The proposed method is simpler than similar intensity measurement techniques and does not require complex preparation.

3. Assessment of the potential emergency hazard of the gas distribution system during operation

Author

O N Medvedeva and S D Perevalov

Abstract

The object of the study was the gas distribution networks of various pressure categories that supply gas to municipal and industrial consumers from gas supply points, for example, gas distribution stations (GDS), during operation process the gas networks are exposed to a large range of loads and impacts, which, in combination with a long period of operation, leads to a decrease in the level of reliability. Studies have shown that the reduction of the emergency hazard for the used pressure categories in the gas distribution network in comparison with the higher category is 1.2 – 2 times, while at the same time there is decrease in the reduced costs to 40 percent or more.
