The beamline’s 120x120 nm focus size, 3.1x3.1 mrad beam divergence, and 9·10¹¹ ph/s flux at 22-67 keV energy, allows experiments with better temporal and spatial resolution than lower energy and lower stability light sources. To further utilize its potential, a new Micro CT station is under development to perform experiments with 0.5-55 um resolution, and up to 4 Hz sample rotation. To achieve this, a model of the disturbances affecting the station was developed, which comprised: i) the characterization and simulation of disturbances, such as rotation forces; and ii) the modeling of the dynamics of the Micro-station. The dynamic model was built with the in-house developed Dynamic Error Budgeting Tool, which uses dynamic substructuring to model 6 degrees of freedom rigid body systems. This work discusses the tradeoffs between rotation-related parameters affecting the sample to optics stability and the experiment resolution in the frequency domain integrated up to 2kHz.
