Description

Progresses on the design of an inner mini Beam-Beam (MBB) monitoring de- tector to help triggering the TOF is described. This consists of a cylinder 60 cm in length and 52 cm in diameter with strips located on the surface of the cylinder along its axis consisting in arrays of 2cm x 2cm x 0.3 cm${}^3$ scintillating plastics separated by 1cm. This detector is proposed to be part of MPD and is being developed by the MexNICA group. We also show the first mechanical and structural design for mBB together with the corresponding strength and mechanical simulation results using the CAD software. Also, using MC simulations, we show the performance of the scin- tillating plastic squares coupled each to four SensL Silicon Photomultipliers (SiPM) sensors. These studies show the importance of sensor location on the plastic sensitive area. Finally, we describe the advances in the front-end design based on fast signals from the used SiPMs. Triggering instrumentation design for Time of Flight (TOF) detector awake is also presented along with TRB3 interfacing for fast signal processing, independent from trigger circuitry.
