Abstract
The Transition Radiation Tracker, made of 370000 cylindrical straws, is a combined tracking and electron identification detector, which is part of the ATLAS Inner Detector at the CERN LHC. The TRT on-detector electronics is made of 2 types of custom asics, handling the analogue signals from the straws, providing a ternary encoded output (ASDBLR), binning the incoming tracking discriminator signal into 3.25ns bins and storing up to 6 microseconds of level 1 storage (DTMROC). This on-detector electronics is joined to the off-detector electronics via patch-panels in charge of data distribution. The off-detector is comprised of three types of modules: the Timing, Trigger and Control (TTC) module, the ReadOut Driver (ROD) and the ReadOut Buffer (ROB). TRT readout system was already described [1],[2],[3]. The status of the final system for ATLAS application will be given. I. ATLAS/TRT READOUT
