| Sumario: | The calibration pulser in the ATLAS Forward Calorimeter electronics is used to 1) directly calibrate the warm, active electronics and 2) diagnose the cold, passive electronics chain all the way to the liquid argon electrodes. The study presented here shows that reflections of the calibration pulse coming from discontinuities located at or between the warm preamplifier and the electrode can differentiate and identify all known defects so far observed in this chain. |
