The Fast Interaction Trigger detector is a trigger detector that informs which events are recorded by A Large Ion collider Experiment at the Large Hadron Collider. In the present study, we evaluate the geometric trigger efficiency of FIT. We do so via simulations of collision events, using PYTHIA 8.2 along with a filtering algorithm, which determines which products of collisions are within the regions covered by FIT. We control different acceptance conditions and calculate the efficiency accordingly. We find that the efficiency decreases at low multiplicity, high particle threshold, and conditions where both sides of FIT are hit by particles.
