The instrument, composed by different units, is sensitive in the range 1 keV - 20 MeV. The total isotropic detection area will be 3.0 m2 with a FOV of about 1.35 sr. The WFM will allow the detection and spectroscopic and polarimetric characterization of all classes of GRBs. Each module is a coded mask telescope that will allow the source localization within few arcmin up to 50-100 keV. The detector core is based on the coupling of low-noise, solid-state Silicon Drift Detectors (SDDs) with CsI(Tl) scintillator bars. Low-energy and highenergy photons are discriminated using the on-board electronics. The instrument design and preliminary experimental characterizations are reported and discussed.ELETTRONICOenConference paper10.1117/12.2314473000452819200145https://www.spiedigitallibrary.org/conference-proceedings-of-spie/10699/2314473/The-wide-field-monitor-and-spectrometer-instrument-on-board-the/10.1117/12.2314473.full?SSO=12018SPIE10699E..5ZFFIS/05 - ASTRONOMIA E ASTROFISICA
