Abstract

The Large Hadron Collider forward (LHCf) experiment was motivated to understand the hadronic interaction relevant to the cosmic-ray air shower development. LHCf has installed compact calorimeters at the LHC and observed neutral particles emitted around zero degree during 0.9, 2.76 and 7 TeV pp collisions and 5 TeV pPb collisions. Since the next operation in 2015 is expected under much higher radiation dose, we have upgraded the detectors, especially their scintillators, to be radiation harder. In this paper, we report the performance of the new imaging sensor, GSO-bar hodoscope tested by heavy-ion beam and 50-250 GeV electron beams. As the result, shower-peak position resolution of 123 μm for 100 GeV electron induced showers was achieved that is satisfactory for our physics goal.
