Example of the power density implementation in OASYS: the looping mechanism is extended by a new looping point capable of sampling the energy spectrum calculated by XOPPY and sending the obtained energy intervals to the new undulator widget. The undulator widget generates rays based on the spatial and angular probability distribution of the radiation calculated by SRW. The rays are then used to compute the power density at several locations of the beamline by using the new plotting widgets: at the front-end mask (transmitted power), on the surface of the ellipsoid mirror (transmitted and absorbed power), and at the focus where a beam defining aperture (BDA) is located (incident power).
