Design of focusing and deflection system of electron welder
Franc, Viktor ; Sháněl, Ondřej (referee) ; Zlámal, Jakub (advisor)
Main parts of the electron beam welder are the source of electrons, accelerator, magnetic lens with deflection coils and stigmator, welding chamber with manipulation stage for welding object and vacuum system. This master thesis starts the design of the electron beam welder prototype. More precisely it is aimed not only on electron optic design, but also on construction of magnetic lens, deflection coils, stigmator, welding chamber and vacuum system.

Stanovení herbicidů pomocí kapilární elektromigrační techniky
Janštová, Lenka
This thesis on the determination of herbicides by capillary electromigration techniques in the first part focuses on the description of electromigration methods, herbicides and possibilities of their determination using chemical analytical methods. The next section describes the Isotachophoretic analysis and electrolyte system used for the determination of glyphosate. Further described is the determination of glyphosate in effluent using accumulation at the asymmetric neutralization boundary purposefully created in capillary. The results, obtained from the real sample, are evaluateded and discused in the final part of thesis.
