A very forward calorimeter for the LHC: Experimental results.

Abstract We report on measurements performed on a liquid scintillator calorimeter prototype designed for the very forward region in an experiment at the LHC. The liquid scintillator technique has the well known advantages of high speed, low noise and radiation hardness. The proposed solution is a SPACAL-like calorimeter with liquid scintillator circulating in quartz tubes positioned in a lead matrix. The beam tests were performed at the CERN SPS with electrons and pions in the range 20–120 GeV. Results on the energy response and resolution are presented.
