A new Testing Scheme for DCS- and Readout-Electronics of the ALICE Transition Radiation Detector — •Philipp Lüttig — Institut für Kernphysik Frankfurt

With the start of the LHC at CERN, one of the four main experiments, ALICE, starts its operation. ALICE is built for exploring the properties of hot and dense matter formed in heavy-ion-collisions, and especially for studying a possible transition to the quark-gluon-plasma (QGP). The ALICE Transition Radiation Detector (TRD) can separate electrons and pions with high precision, and can track the emitted particles after a collision. The TRD consists of 18 supermodules with 30 read-out chambers in each supermodule. The supermodules are arranged radially around the beam axis. At the Institut für Kernphysik Frankfurt the read-out chambers are equipped with Front-end electronics and cooling units, followed by a detailed testing procedure.
In this talk we discuss the test infrastructure and the different hardware and software components implemented in the testing process. Based on a modified data format, optimized for the testing, the noise characteristics in different test configurations are reviewed. New Graphical User Interfaces customized for process visualization and the analysis of test data will be presented.
