Abstract
We describe the design of the analog portion of an electronics system to process signals from the photomultiplier tubes of the ATLAS Tile Calorimeter. The system has a 16-bit dynamic range and is capable of measuring energy depositions in a single calorimeter cell from â¼20MeV to â¼1.3TeV. In order to maintain the calorimeter calibration at the 1% level the system includes a charge injection circuit and a current integrator for use with a cesium source system and with the time-averaged currents produced by the LHC. The system also provides a signal for an analog adder which produces an energy sum for each calorimeter tower. Over 10,000 channels of this system have been constructed and delivered for use.
