Description

Totem is exploring the forward region at pseudorapidity larger than 3.1; its main goal is the measurement of the total and elastic cross-section at 14 TeV and the study of diffractive physics in the forward region. The experiment is now built and almost completely commissioned; data taking started in December 2009. TOTEM aims at measuring the total cross section beyond 1 TeV/c with the unprecedented precision of 1 % by using the luminosity independent method, based on the simultaneous detection of elastic scattering at low momentum transfer and of the inelastic interactions. To achieve this, protons scattered at very small angles in elastic or quasi-elastic reactions will be measured in telescopes of silicon detectors enclosed in Roman Pots, placed on both sides of the intersection regions; inelastically produced secondaries will be measured by a forward inelastic detector covering the region 3 < eta <7 with full azimutal acceptance. The TOTEM physics program includes the measurement of forward charged multiplicity distributions at the TEV scale, important for the understanding of the cosmic ray events. TOTEM will take data under all LHC beam conditions including standard high luminosity runs to maximize its physics goals.
