    Abstract

    The LHC forward (LHCf) experiment is an experiment to measure the neutral particles emitted in the very forward region of the collision point of LHC. Its goal is to provide data to discriminate the various hadronic interaction models used in cosmic-ray physics. The first phase of the experiment has been achieved on July 2010 with center-of-mass energy vs =7 TeV, and the first result has been submitted. The data analysis of data is still ongoing. The next phase is planned on 2014 at vs = 14 TeV. An upgrade of the detector is necessary to cope with the radiaiton damage of our plastic scintillator and the position sensitive scintillating fiber (SciFi) due to the higher beam intensity with the higher energy than the 7 TeV case. For this purpose, GSO scintillator, which has a high radiation resistivity, has been chosen. Small scaled GSO scintillators (GSO bars) have been manufactured to construct a position sensitive detector. The detector, GSO bundle, consists of GSO bars in a single hodoscope plane. In this paper, we describe the expected performance of a GSO bar system in order to replace SciFi. For this purpose, we made a single layer hodoscope consisting of several GSO bars and performed tests using low-energy heavy ion (Carbon) beam as well as cosmic ray muons. We discuss mainly the position resolution and the simulated performance when the system is applied to cascade showers.
