Introduction,and where the energy distribution, and frequently also the angular distribution, of the scattered electrons is measured. The generally used acronyms for the technique are HREELS (.igh .esolution .lectron Energy Loss Spectroscopy) or EELS.

The Computational Procedures,tions readily available, analytical calculations, in particular the use of cumbersome perturbation theories, are being increasingly replaced by numerical studies. This chapter outlines the basic concepts and numerical methods employed in this volume.

The Electron Optics of the Cylindrical Deflector,ors terminated by equipotential plates have no disadvantages compared to an ideal field termination when the deflection angle is properly adjusted. Cylindrical deflectors can also be used as retarding devices, which allows a stepwise monochromati-sation of a beam, without intermediate lenses for ret

Comparison of Experiment and Simulation,ion and acceptance angles at the target are compared to results from numerical simulations, and nearly perfect agreement is found. The performance of the spectrometer is demonstrated with the vibration spectrum of a monolayer of CO featuring a resolution of better than 1 meV.

There are several pioneers who made monumental contributions to the development of this access to deep-seated cranial-base lesions.

More recent investigators have reported improved, unchanged, and impaired hemodynamic function with HFV under a variety of experimental conditions (Table 1).
