Scintillation Detector of Secondary Electrons for ESEM
Čudek, Pavel ; Špinka, Jiří (referee) ; Jirák, Josef (advisor)
The thesis deals with modifying and biulding of scintilation detector of secondary electrons for environmental scanning electron microscopy. It describes dilemma of environmental scanning electron microscopy, types of detectors and secondary electrons detection. The experimental part of this thesis focuses on the design and construction of new scintillation detector on the basis of simulations secondary electrons trajectories. Identifying the parameters, pressure dependencies and optimizations of electrode system of the detector realized.

Scintillation SE detector for VP SEM
Račanský, David ; Čudek, Pavel (referee) ; Jirák, Josef (advisor)
First part of this thesis is a theoretical essay which deals with the basics of the variable pressure scanning electron microscope, includes detection of secondary electrons with a view to a scintillation detector. The first applied part of the thesis is focused on prediction, measuring and setting-up optional working parley in vacuum electrodes scintillation detector system, with a stress small diameter hole in screenings C1 and C2. Second applied part was verify a change of working distance between sample and detector in consequence to optional solution for another work.
