This paper reports the performance characteristics of a-Si detectors with Ir-192 gamma source. Imaging performance of the detector system is evaluated using contrast sensitivity over a range of material thickness of steel, signal to noise ratio, dynamic range and linearity. The radiographic sensitivity was observed over a range of thickness of steel using standard image quality indicators. Quan...

This Note describes calculations of the shielding necessary to reduce the dose rate to less than 0.05 mrem/h when synchrotron radiations emitted by the LCLS electrons beam hit a worst type scattering target located in the hard X-ray line. The calculations were performed using the FLUKA Monte-Carlo code and as well as the STAC8 analytical code. The photon spectrum used as a source term correspon...

The influence of magnesium anode dissolution in pipe filled with potable water on the steel corrosion rate was investigated. Steel measured using weight loss technique, and linear polarization resistance measurements were used to estimate formation kinetics protective abilities phase layer metal surface. cathodic current distribution along a microammeter compared computer model. results clearly...

Biofilm formed on carbon steel by various species of bacterial cells causes serious problems such as corrosion of steel, choking of flow in the pipe, deterioration of the heat-transfer efficiency, and so on. Cathodic protection is known to be a reliable method for protecting carbon steel from corrosion. However, the initial attachment of bacteria to the surface and the effects of cathodic prote...

Optical microscopy, total oxygen measurements and slime tests have been conducted to quantify the size distribution and amount of inclusions at various processing steps during basic oxygen furnace (BOF) based steel production at Baosteel. The effects on steel cleanliness of specific operational improvements during steel refining and continuous casting have been investigated. Such improvements t...
