Abstract:
Two calorimeters are foreseen in the very forward region of the ILC and CLIC detectors: The Luminosity Calorimeter (LumiCal) for the precise measurement of the luminosity and the Beam Calorimeter (BeamCal) for the fast estimate of the luminosity and tagging of high energy electrons.
A fully assembled sensor planes of the LumiCal calorimeter has been operated in mixed particle beam (electrons, muons and pions) at the CERN PS facilities with 5 GeV beam momentum. The experiment was performed to test the feasibility and performance of the various technologies. The results demonstrate very good performance of the response of full readout chain to beam particles for silicon sensors. In addition, studies of the shower development using tungsten absorber planes were done.
