Abstract: We propose performing an experiment to search for a new hidden sector vector boson coupled via baryonic current ($V_B$ or ``dark omega'') in the (140--650) MeV mass range. It will be produced on low-Z fixed targets using high energy intense electron beams. The multi-gamma decay of this particle will be detected by a high resolution and large acceptance crystal calorimeter providing a few MeV level resolutions in $M_{\gamma\gamma\gamma}$, critically important for the signal to background separation. The motivation, feasibility studies of the setup and estimation of the realistic parameter space of the proposed experiment is discussed.
