A new concept for experiment program planning for the fusion experiment Wendelstein 7-X

The control and data acquisition system (codac system) for the fusion experiment Wendelstein 7-X is designed for miscellaneous operational scenarios: short pulses with arbitrary intervals, steady-state long pulse operation and arbitrary sequences of short phases with different characteristics in one discharge. Due to the multitude and diversity of the necessary settings of an experiment program special attention must be paid to experiment planning. The reduction of the editable parameters depending dedicated to the particular experiment task is an important requirement. Furthermore experiment planners prefer a more abstract and physics-oriented description. This contribution introduces a concept for experiment planning based on so called segment program boxes (SegProgBox). The planned work flow of experiment program creation will be discussed after an introduction of the SegProgBox design.
