The scan box or scan controller is a component that is used to deflect a beam of charged particles in a controlled manner.
The scan box is instructed by (an) instance(s) of NXprogram, some control software, which is not necessarily the same program as the one controlling other parts of the instrument.
The scan box directs the probe of charged particles (electrons, ions) to controlled locations according to a scan scheme and plan.

Name of the typically tech-partner-specific term that specifies an automated protocol which details how the components of the scan_box and the instrument work together to achieve a controlled scanning of the beam (over the sample surface).
Oftentimes users do not need to or are not able to disentangle the intricate details of the spatiotemporal dynamics of their instrument. Instead, often they rely on the assumption that the instrument and its controlling programs work as expected. The field scan_schema can be used to add some constraints on how the beam was scanned over the surface.

Time period during which the beam remains at one position.
This concept is related to term Dwell Time of the EMglossary standard.

Time period during which the beam moves from the final position of one scan line to the starting position of the subsequent scan line.
This concept is related to term Flyback Time of the EMglossary standard.

Details about components which realize the deflection technically.
This concept should be used for all those components that implement the scanning of the beam, while components like beam blankers etc. should use rather the NXdeflector concept of the NXebeam_column base class.
CIRCUIT: (optional) NXcircuit
