Surface material dependence of beam-tilted-foil orientation and alignment

Orientation of hydrogen 2p after tilted-foil excitation.

Observation of beam-induced changes in the polarization of Balmer- alpha radiation emitted following beam-tilted-foil transmission.

Measurements of the circular polarization of Balmer-u radiation emitted by excited hydrogen atoms, following the transmission of (20—50)-keV protons through thin, tilted amorphous carbon foils, exhibit markedly unexpected behavior as a function of exposure of the foil to the proton beam. Specifically, the circular polarization changes from an initially well understood tilt-angle dependence to a...

Beam – Tilted Correlations

A model is described and evaluated that calculates beam irradiance from tilted solar radiance. This model will then be used to estimate the performance of a photovoltaic system using only tilted data values and compared to results using measured direct normal beam values. The results and advantages of this model will then be discussed along with the limitations of this model.

Orientation of 1s electrons using tilted foils

The prospects for producing orientation of the 1s level in highly charged ions using tilted foils is discussed. We analyse the transfer of orientation from the initial orbital angular momentum of an ion emerging from a foil to the ground-state spin via a combination of the spin–orbit interaction and cascade decays. An enhancement of the orientation can be obtained using a multi-tilted-foil tech...
