Abstract

International audienceWe report the results of tests of 12880 Very Front End (VFE) readout cards for the barrel of the CMS electromagnetic calorimeter. A thorough test sequence was applied to each card including power-on test, burn-in and final calibration. Cards failing the tests were at the few per mille level. The results prove the very high quality of the VFE cards
