ALICE Run Control Center

The Experimental Physics (EP) Department carries out research in the field of experimental particle physics.
It aims to provide a stimulating scientific atmosphere and remains an important reference centre for the European physics community. It contributes to the education and training of young scientists.

EP is one of the largest departments at CERN, with about 500 staff members and over 300 other members of personnel: Fellows, Associates, Students and Apprentices. In addition it hosts the approximately 12,000 Users that visit CERN from their home institutes around the world to perform scientific research.
