We use the Lie series averaging method to obtain a complete second order solution for motion of a charged particle in a spatially periodic magnetic field. A comparison is made with the first order solution obtained previously by Coffey.

Distribution of the roots of dispersion equation of the parametric Cherenkov radiation (PCR) excited by uniformly moving charged particle in an ideally conducting metal waveguide filled with a spatially periodic layered dielectric is studied. The study both in long wavelengths range and in the range of wavelengths comparable and smaller than the period of non-uniformity is presented. It is shown that in the case of long wavelengths the dependence of the frequency of the excited PCR on the particle velocity is monotonic. For the case of wavelengths comparable and shorter than the non-uniformity period the spectrum of PCR is more complicated. Its characteristic features are determined.

The Smith-Purcell radiation of a charged particle moving in a periodic structure is analysed theoretically. The considered structure consists of two planar diffraction gratings with different periods which are formed by parallel conducting wires. The analytical expression for the spectral-angular distribution of radiation is obtained. It is shown that the angular distribution of radiation can be made narrower by using two gratings instead of one, and radiation intensity can be manipulated by parallel relative shift of gratings. The obtained results are of great importance for the research and development of high power radiation sources based on volume free-electron lasers.

ABSTRACTDescribed are results showing that an oscillating flow-field can induce spatially periodic composition variations in electrodeposited NiFe films. Flow-induced NiFe composition modulated alloys (CMA's) were deposited on the disk of a rotating disk electrode by oscillating the disk rotation rate during galvanostatic plating. Deposit composition and structure were investigated using potentiostatic stripping voltammetry and scanning probe microscopy. Results illustrate a linear relationship between the composition modulation wavelength and the flow oscillation period. CMA's with wavelengths less than 10 nm can be fabricated when plating with a disk rotation rate oscillation period less than 3 seconds.
