Ionization Detector for Variable Pressure SEM
Černoch, David ; Špinka, Jiří (referee) ; Jirák, Josef (advisor)
This graduation theises deal with influence of an additional grating possitioned berween the sample and the ionisation detektor of the environmental scannin elektron microscope on signal detection. Signal level is measured for changing pressure, at different voltages on the aditional grating, at different sample - additional electrode distance and at different sample - detektor distance. Influence of the additional grating is simulated for real working conditions on PC.
