Popis:	A rigorous analytical calculation of the time-aberration coefficient (TAC) is obtained for combined lenses whose accelerating electrode is in the vicinity of a cathode. The results thus obtained are verified by comparison with a least-squares method TAC calculation which requires no less than 10 electron trajectories in conjunction with the time-of-flight. By contrast, the present algorithm requires only two trajectories in the paraxial approximation and obviates the time-of-flight. The calculation neglects the magnetic field of the cathode-accelerating electrode region.
