Some aspects of creation of the magnetically focused streak tube, including results of computer designing of its electron-optical system are calculated. The designing was carried out with use of a package of the programs ELIM-E. As a result of the work it was possible to show an opportunity of creation of streak tube with magnetically focused, in which the magnetic lens with the armored permanent magnet is used, and also to confirm efficiency of algorithms used in a package of the programs ELIM-E.
