Secondary-electron yields and their dependence on the angle of incidence on stainless-steel surfaces for three energetic ion beams
Secondary-electron yields were investigated for 28-MeV protons, 126-MeV oxygen-ions, and 182-MeV gold ions incident on 304 stainless-steel surfaces. The dependence on the incidence angle was studied in detail, and a system was developed which allows accurate measurements to be performed over a wide angular range extending to nearly grazing collisions. Electron yield estimates of interest for fu...
متن کاملEffect of Solar Angles on Incident Energy of the Flat Collectors
In this paper the daily, monthly, seasonally, and yearly optimum slope angles of solar collectors are determined for areas in Iran and new models are developed to calculate the monthly, seasonally, and yearly optimum slope angles for latitudes of to north. To achieve this purpose, the slope and surface azimuth angles of solar collectors for receiving maximum solar radiation were determined ...
متن کاملExperimental Studies on Grooved Surfaces to Suppress Secondary Electron Emission
Grooved surfaces are effective to suppress the secondary electron emission, and can be a promising technique to mitigate the electron cloud effect in positron/proton storage rings. Aiming for the application in a dipole-type magnetic field, various shapes of triangular grooved surfaces have been studied at KEK. The grooves tested here have vertex angles of 20−30°, depths of 2.5−5.0 mm, and vert...
متن کاملA simple route to carbon micro- and nanorod hybrid structures by physical vapour deposition
Tilted well-aligned carbon microand nano-hybrid rods were synthesized on Si at different substrate temperatures and incident angles of carbon source beam using the hot filament physical vapour deposition technique. The morphologic surfaces, chemical compositions and bond structures of the oblique carbon rodlike structures were investigated by scanning electron microscopy, field emission scannin...
متن کاملبهینهسازی پاسخ دزیمتری نوترون در بازه انرژی حرارتی و سریع برای آشکارساز دیودی
During the last few years, real time gamma and neutron dosimeters have been developed and semiconductor diodes are frequently used in these dosimeters. Semiconductor diodes are used to charged particle detection. For sensitizing the detector to neutrons, a converter layer is contacted on the front surfaces of them. Incident neutrons interact with the converter and produce charged particles that...
