Typically tech-partner, microscope-, and control software-specific name of the specific operation mode how the ebeam_column and its components are controlled to achieve a specific illumination condition.
In most cases users do not know, have to care, or are able to disentangle the details of the spatiotemporal dynamics of the components of the microscope. Instead, they rely on the assumption that the microscope and control software work as expected. Selecting then a specific operation_mode assures some level of reproducibility in the illumination conditions.
FABRICATION: (optional) NXfabrication
CHAMBER: (optional) NXchamber
electron_source: (optional) NXsource
