Description

A large lead-liquid scintillator electromagnetic calorimeter has been built for a 'direct photon' experiment at CERN. Gain equalisation and monitoring of the calorimeter were achieved by two complementary computer-controlled calibration systems, a laser system connected by optical fibres and a system of moveable radioactive sources. Final corrections to the equalisation were made using the physics data recorded during the experiment. (orig.)
