    A new accelerator experiment to study very forward particle emission in the LHC collider, LHCf, is presented. Because a collision of 7 TeV protons corresponds to 1017 eV in the laboratory system, our experiment can give a firm base for simulating air showers generated from ultra high energy cosmic rays. This is indispensable information for the ongoing large experiments like TA, Auger and EUSO for the near future. The LHCf detector is composed of three tower electromagnetic calorimeters and scintillating fibers (SciFi) to measure core position of the shower. To avoid multi particle hits, each tower has a small cross section (2cm ×2cm, 3cm×3cm and 4cm×4cm). We have confirmed that we can measure shower energy with <5% resolution even using such small calorimeters. A project overview and the results of a beam test carried out in August 2004 at CERN SPS are presented.
