As they appear to be very promising, here we summarize the main reasons and goal of such a LGS-dedicated WFS and present the concept behind the code developed to produce numerical simulations, exploring the space of parameters. We report different approaches for the approximation of the extended source and the model adopted for the ingot prism simulation.ELETTRONICOenConference paper10.1117/12.23132192-s2.0-85053539951000452819300028https://www.spiedigitallibrary.org/conference-proceedings-of-spie/10703/2313219/Dealing-with-the-cigar--preliminary-performance-estimation-of-an/10.1117/12.2313219.full2018SPIE10703E..0VVFIS/05 - ASTRONOMIA E ASTROFISICA
