The 6300FS machine was installed at UCSB in May 2007.
This system uses the vector scan approach for electron beam deflection within a field, step and repeat for stage movement between fields, the combination of which allows the entire area of the sample to be exposed to the electron beam.
The machine can be run at 25, 50 and 100 kV. Note however that only the 100kV mode is used at UCSB.
