Abstract

In future electron-positron collider detectors, special calorimeters are needed in the very forward region; one of them, the Beam Calorimeter (BeamCal) is designed as a GaAs-Tungsten sandwich calorimeter. Several GaAs sensor sectors were tested in the laboratory. The current as a function of the voltage was measured for each pad and found to be about 100nA at 60V. One sensor sector was assembled with fan-out electronics bonded on one side to a sensor pad and on the other side to an front-end (FE) ASIC. The fully assembled system was then investigated in an electron beam. Preliminary results of the test beam data analysis are reported. Charge collection efficiency (CCE) and signal to noise were calculated form test beam data.
