	Diagnostics and Optimization of a Wien Filter for Mass Separation of Ions Joch, Vítězslav ; Bábor, Petr (referee) ; Voborný, Stanislav (advisor) This bachelor thesis deals with measurement of the basic parameters of Wien filter for mass separation of ion focused beam. One part of the thesis is finding the right operational parameters of the ion gun for deposition of ultra-thin films with redesigned Wien filter. The next part of the thesis deals with a design and realization of a Faraday cup for measurement of the current density profiles of the focused ion beam. Detailed record

	Programy pro elektronově optický návrh Lencová, Bohumila ; Oral, Martin The paper gives a brief overview of computational method used in the Institute of Scientific Instruments of AS CR for the design of electron optical devices. New possibilities of the software are then illustrated on the computations of spot profile in a scanning electron microscope with low energy and Wien filter. Detailed record
	Design of low energy SEM Vlček, Ivan Paper briefly describes main features of proposed low-energy electron scanning microscope. Detailed record
	Theoretical and experimental study of a Wien filter properties for using at the very-low-energy scanning electron microscope Vlček, Ivan Results of Wien filter study are employed for design of a very low-energy scanning microscope. A Wien filter serves as a separator of primary and signal electrons in this arrangement. The paper describes design of other optical parts of the microscope: objective lens, deflection system and CCD detector optics. Detailed record
	Theoretical and experimental study of the Wien filter properties for the application in a scanning microscope with very low energy Vlček, Ivan The work aims to verify experimentally the Wien filter properties and the validity and exactness of numerical calculations of electric and magnetic fields and electron optical properties for this rotationally non-symmetrical energy-dispersion element. Detailed record
	Theoretical and Experimental Study of Wien Filter Properties for Use in the Scanning Very Low Energy Electron Microscope Vlček, Ivan Detailed record
	Návrh nízkoenergiového REM Vlček, Ivan ; Lencová, Bohumila ; Horáček, Miroslav Our aim is to redesign the low-energy SEM (a scanning LEEM) in an UHV apparatus designed in our institute to allow the detection of the angular distribution of signal electrons. For this purpose we have to separate the signal electrons from the primary beam with a Wien filter and project the image of the back-focal plane of the objective lens on an area-sensitive detector (a back-illuminated CCD). Therefore we have to design a new electrostatic optics working in UHV Detailed record
