  We present the conceptual design for the miniBeBe detector proposed to be
installed as a level-0 trigger for the TOF of the NICA-MPD. We discuss the
design and the geometrical array of its sensitive parts, the read-out
electronics as well as the mechanical support that is envisioned. We also
present simulation results for p + p and Bi + Bi collisions to study its
capabilities as a function of multiplicity both as a level-0 trigger for the
TOF, as well as to serve as a beam-gas interaction veto and to locate the
beam-beam interaction vertex.
