The TOTEM experiment

Risultati immagini per totem cernTOTEM’s physics program is dedicated to the precise measurement of the proton-proton interaction cross section, as well as to the in-depth study of the proton structure which is still poorly understood. The study of the physics processes in the region very close to the particles beam (forward region) is complementary to the programs of the LHC general-purpose experiments and requires appropriate detectors.

That’s why, the TOTEM collaboration had to invest heavily in the design of sophisticated detectors characterized by a high acceptance for particles produced in that very busy region. All the detectors of the experimental apparatus detect charged particles emitted by the proton-proton collisions in the IP5 interaction point and have trigger capabilities that allow an online selection of specific events.
