Y. Li et al., THE RELATIVISTIC 5TH-ORDER GEOMETRICAL ABERRATIONS OF A COMBINED FOCUSING DEFLECTION SYSTEM, Journal of physics. D, Applied physics, 26(4), 1993, pp. 522-538
The relativistic fifth-order geometrical aberrations of the combined f
ocusing-deflection system and their coefficients have been derived. Th
e variational functions and some of their gradients are given as are a
ll aberrations and the fundamental method of derivation with software
REDUCE.
