Abstract
The LHCf is one of the LHC forward experiments and the aim is to measure energy and transverse momentum spectra of gamma-rays and neutral hadrons emitted in the very forward region of LHC. In 2009, LHC started the operation and LHCf has taken data at p s =900GeV. The measured spectra of gamma-ray like events and hadron like events are in good agreement with the Monte-Carlo simulation results generated by the QGSJET2 model within error. In 2010, LHC are delivering pp collisions at p s =7TeV and LHCf are taking data with very low beam-gas background level of less than 1%.
