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