ABSTRACT
The effect of the surface roughness on a moving electron bunch is considered by resorting to a model of a metallic structure with random perturbations on its surface. Based upon this model, analytic expressions have been derived for the average energy emitted per groove (EPG) and for its standard deviation. For a relativistic bunch, both quantities are shown to be virtually independent of the momentum. Moreover, it has been found that the standard deviation of the EPG is proportional to that of the roughness parameter to the power of 1/4. © 2004 American Institute of Physics.

    Properties of femtosecond laser-induced ripples on patterned metal surfaces are investigated through using a crossed two-step line-scribing method. It is found that the ripple periodicity tends to decrease with larger surface roughness but increase with higher laser fluence. For the increased...

    The water dimer interaction energy and its convergence to the basis set limit was investigated, with electron correlation effects treated at the level of second order Møller-Plesset perturbation theory (MP2). ANO-type and large uncontracted basis sets were used, spreading over a wide range in...

    The semiclassical perturbation theory formalism of Hubbard and Miller [J. Chem. Phys. 78, 1801 (1983)] for atom surface scattering is used to explore the possibility of observation of heavy atom diffractive scattering. In the limit of vanishing h the semiclassical theory is shown to reduce to...

    Describing and modelling a machined surface require the selection of relevant roughness parameters. However, this selection is difficult since a machined surface morphology can be described by a large number of roughness parameters. This investigation focuses on the roughness of metallic...

    The measurement of minute changes in local gloss has not been presented in international standards due to a lack of suitable glossmeters. The development of a diffractive-element-based glossmeter (DOG) made it possible to detect local variation of gloss from planar and complex-shaped surfaces....
