Abstract: A new design of a detector plane of submillimetrethickness for an electromagnetic samplingcalorimeter is presented. It is intended to be used in the luminometersLumiCal and BeamCal in future linear e+e− colliderexperiments. The detector planes were produced utilisingnovel connectivity scheme technologies. They wereinstalled in a compact prototype of the calorimeter and testedat DESY with an electron beam of energy 1–5 GeV. Theperformance of a prototype of a compact LumiCal comprisingeight detector planes was studied. The effective Molièreradius at 5 GeV was determined to be (8.1 ± 0.1 (stat) ±0.3 (syst)) mm, a value well reproduced by the Monte Carlo(MC) simulation (8.4 ± 0.1) mm. The dependence of theeffective Molière radius on the electron energy in the range1–5 GeV was also studied. Good agreement was obtainedbetween data and MC simulation.
