Title: | Differential algebraic method for arbitrary order curvilinear-axis combined geometric-chromatic aberration analysis | Authors: | Cheng, M. Tang, T. Lu, Y. Yao, Z. |
Issue Date: | 7-Apr-2003 | Citation: | Cheng, M., Tang, T., Lu, Y., Yao, Z. (2003-04-07). Differential algebraic method for arbitrary order curvilinear-axis combined geometric-chromatic aberration analysis. Journal of Physics D: Applied Physics 36 (7) : 924-928. ScholarBank@NUS Repository. https://doi.org/10.1088/0022-3727/36/7/323 | Abstract: | The principle of differential algebra is applied to analyse and calculate arbitrary order curvilinear-axis combined geometric-chromatic aberrations of electron optical systems. Expressions of differential algebraic form of high order combined aberrations are obtained and arbitrary order combined aberrations can be calculated numerically. As an example, a typical wide electron beam focusing system with curved optical axes named magnetic immersion lens has been studied. All the second-order and third-order combined geometric-chromatic aberrations of the lens have been calculated, and the patterns of the corresponding geometric aberrations and combined aberrations have been given as well. | Source Title: | Journal of Physics D: Applied Physics | URI: | http://scholarbank.nus.edu.sg/handle/10635/114635 | ISSN: | 00223727 | DOI: | 10.1088/0022-3727/36/7/323 |
