This paper describes electrothermal microactuators that generate rectilinear displacements and forces by leveraging deformations caused by localized thermal stresses. In one manifestation, an electric current is passed through a V-shaped beam anchored at both ends, and thermal expansion caused by joule heating pushes the apex outward. Analytical and finite element models of device performance a...

To fulfil the requirement on beam luminosity the ion source has to deliver a cold and intense proton beam with a generalized perveance of K = 3.1·10. Therefore, it was decided to use a hot filament driven gas discharge ion source providing very small beam emittances due to the very low plasma temperature. Furthermore, this source type is able to produce high beam intensities. Preliminary experi...

In an electron beam sustained discharge Xenon laser the discharge energy deposition has been varied in order to investigate the saturation effect on the Xenon laser. The current density of the electron beam is varied separately in the range of 0.1-2.7 A/cmz to obtain optimized discharge excitation conditions as a function of electron beam current density and gas pressure. An optimal fractional ...

Due to their sensitivity to impact-induced delamination, woven fabric reinforced polymer composites have limited practical applications. Hybridization of polymer composites has been proposed as a solution to this problem. In this study, the effects of fiber reinforcement type, hybridization method, plies stacking sequence and loading rate on mode I delamination behavior of pure basalt, pure nyl...
