##### Beam
|
||||
- **Aperture** probe forming aperture gives probe semi-angle (α)
|
||||
- **Energy** energy of primary electron beam in keV ... gives final pixel size
|
||||
- **Energy** energy of primary electron beam in keV
|
||||
- **Probe** probe setting together with chosen probe forming aperture give probe current
|
||||
- **Defocus** moves focus out of the sample plane - enlarges beam diameter
|
||||
##### Scanning
|
||||
- **Magnification** controls image field of view
|
||||
- **Matrix** gives beam position to position distance + beam defocus = beam overlap
|
||||
##### Camera length
|
||||
- **Nominal CL** sample to detector distance gives maximal detected angle as well as angular sampling
|
||||
- **Nominal CL** sample to detector distance (usually ADF) gives maximal detected angle as well as angular sampling
|
||||
- **Use PAAR** Pumping Aperture Anglar Restriction, build-in aperture may limit maximal scattering angles for shortest camera lengths
|
||||
##### Detection
|
||||
- **Detector** detector used for data collection
|
||||
- **Binning** reduction in pixel array size usually increas maximum frame rate
|
||||
- **Dwell time** single position beam time ... check your detector characteristics
|
||||
- **Binning** reduction in pixel array size usually increases maximum frame rate
|
||||
- **Dwell time** single position beam time
|
||||
|
||||
Always carefully check maximal detector frame rate, needed binning and set dwell time!!
