ZEUS Luminosity Photon Calorimeter Linearity Measurement

Abstract

Report presents the test results of the linearity measurement of the Luminosity Photon Calorimeter readout electronics. Nonlinearity of the preamplifiers, amplifiers, 140 meters long analog signal transmission, integrators and FADC have been measured and analyzed. This allows making data correction and results in increased luminosity measurement precision for off-line processing.
