MAD is intended to be a Multi-Conjugate Adaptive Optics prototype to be tested at VLT Visitor Focus (UT3). It is conceived as a fast-track project by re-using as much as possible key components developed in the scope of existing VLT AO systems. The scope of this document is to present the test relative to the preliminary acceptance test of the LOWFS in INAF - Arcetri. INAF Arcetri team performed the acceptance tests and include the results in this document.ELETTRONICOenResearch reportFIS/05 - ASTRONOMIA E ASTROFISICAERC sectors::Physical Sciences and Engineering
