| contents | As part of the second phase of Advanced Virgo upgrade program, instrumented baffles are being constructed to be installed around the end mirrors in the main arms, in continuation of what has been implemented for the input mode cleaner end mirror during phase I. These baffles will be equipped with photosensors, allowing for real-time monitoring of the stray light around the mirrors. In this paper, we present optical simulations of the light distribution in the detector main cavities to assess the ability of the sensors to effectively monitor misalignment and defects on the mirrors surface and to play a role in the pre-alignment of the interferometer. |
