• A fast electronic system of the T0 start trigger detector for the ALICE experiment has been developed, assembled, and adjusted using a pulsed laser. The system is composed of 24 independent detection channels for secondary particles (this number corresponds to the number of individual Cherenkov counters in the detector); common modules, which generate the signal of the event detection time with an error of <50 ps, the trigger of the interaction vertex position with an error of ∼2 cm, and triggers of two independent levels of the event multiplicity in the range of 1–150 minimum ionizing particles (MIP); and several auxiliary modules. A total of 109 channels are used in the time-to-digital converters to record time, amplitude, and auxiliary data. The time resolution of the detector for single MIP is 38 ps.
