One <strong>of</strong> the most important part <strong>of</strong> the ALICE installation is the T0 detector <strong>for</strong> the trigger and<br />
start system <strong>for</strong> time <strong>of</strong> flight.<br />
The short description and per<strong>for</strong>mance <strong>of</strong> this detector will be presented. High time resolution<br />
was obtained <strong>for</strong> <strong>for</strong> pp interactions about 40 ps and 20ps <strong>for</strong> heavy ions.<br />
The detector is used <strong>for</strong> online luminosity monitoring with fast feedback to accelerator team.<br />
T0 detector supplies five different trigger signals <strong>for</strong> background rejection and physics<br />
selections. The detector shows very good per<strong>for</strong>mance and stable work at high interaction<br />
rate up to 400 KHz.<br />
