Sample
Samples must be conductive. Insulators are hardly imaged due to charging
Sample maximum dimension is 10x10x10 mm to fit sample Holder dimension
Sample Holder scheme (pdf) |
Samples can be heated up during measurements to 1100 K by e-beam bombardment, filaments, Al2O3, BN heaters | |
Samples can be cooled down to 150 K using liquid nitrogen | |
Voltage and Current can be applied to the sample through electrical contacts (3 electrical contacts + 2 Termocouple contacts + GRD) |
|
The maximum pressure allowed during microscopy experiments is 1·10-6 mbar. |
