| heal.abstract | For an ideal hemispherical deflector analyzer (HDA) utilizing a virtual entry aperture, whose size is controlled by an injection lens, the "slit" and angular contributions to the overall base resolution R-B are not independent, but constrained by the Helmholtz-Lagrange law. Thus, R-B becomes a function of the linear lens magnification \M-L\ and has a minimum, (R-Bo) over bar = R-B(\M-L\(o)), at the optimal magnification \M-L\ = \M-L\(o). (R-Bo) over bar and \M-L\(o) are shown to be analytic expressions of basic experimental parameters. (R-Bo) over bar is thus the ultimate resolution that can be attained in this case. The generality and simplicity of this result should be very helpful in the efficient design and performance evaluation of any modern HDA. (C) 2005 American Institute of Physics. | en |
