The Provence Adaptive optics Pyramid Run System (PAPYRUS) is a pyramid-basedAdaptive Optics (AO) system that will be installed at the Coude focus of the1.52m telescope (T152) at the Observatoire de Haute Provence (OHP). The projectis being developed by PhD students and Postdocs across France with support fromstaff members consolidating the existing expertise and hardware into an R&Dtestbed. This testbed allows us to run various pyramid wavefront sensing (WFS)control algorithms on-sky and experiment on new concepts for wavefront controlwith additional benefit from the high number of available nights at thistelescope. It will also function as a teaching tool for students during theplanned AO summer school at OHP. To our knowledge, this is one of the firstpedagogic pyramid-based AO systems on-sky. The key components of PAPYRUS are a17x17 actuators Alpao deformable mirror with a Alpao RTC, a very low noisecamera OCAM2k, and a 4-faces glass pyramid. PAPYRUS is designed in order to bea simple and modular system to explore wavefront control with a pyramid WFS onsky. We present an overview of PAPYRUS, a description of the opto-mechanicaldesign and the current status of the project.
