Coaching station for FIT on-call shifters

Abstract: We present an efficient and cost-effective way to train operators of complex systems with limited accessibility, such as sub-detectors of big experiments at the CERN Large Hadron Collider (LHC). Our coaching station was developed to train on-call shifters for the ALICE Fast Interaction Trigger (FIT). This coaching station significantly reduces the training period and enhances the trainee's confidence in their actions. We hope this work will inspire the construction of comparable training systems for other sub-detectors.
