Abstract
The LHCf detectors are installed in the slot of the TANs (target neutral absorbers) located ±140 m away from the ATLAS interaction point (IP1) and measure secondary neutral particles arriving from the IP1. Inside the TAN, the beam vacuum chamber makes a Y shaped transition from the single copper beam-pipe facing the IP1 to the two separate beam pipes joining to the arcs of LHC. Charged particles from the IP1 are swept aside by the D1 dipole magnet before reaching the TAN. At this unique location the pseudo-rapidity ranges from 8.4 to infinity (zero degrees).
