2.3.3.3.124. NXevent_data_apm_set¶
Status:
base class, extends NXobject
Description:
Base class for a set of :ref:`NXevent_data_apm` instances. ...
Base class for a set of NXevent_data_apm instances.
Members of the set are instances of NXevent_data_apm. These have an associated time interval during which the conditions of the instrument were considered stable and fit enough for purpose.
Which temporal granularity is adequate depends on the situation and research question. Using a model which enables a collection of events offers the most flexible way to cater for both atom probe experiments or simulation.
To monitor the course of an ion extraction experiment (or simulation) it makes sense to track time explicitly via time stamps or implicitly via e.g. a clock inside the instrument, such as the clock of the pulser and respective pulsing event identifier.
As set and measured quantities typically change over time and we do not yet know during the measurement which of the events have associated (molecular) ions that will end up in the reconstructed volume, we must not document quantities as a function of the evaporated_identifier but as a function of the (pulsing) event_identifier.
