چکیده

The Transition Radiation Detector (TRD) [1] is one of the main detector components of the ALICE experiment. It consists of 18 supermodules mounted cylindrical around the beam axis of the LHC. Every supermodule is assembled out of 30 Readout Chambers (ROC) of different types. These ROCs are equipped with front end electronics (FEE) and tested at the Institut für Kernphysik Frankfurt (IKF) [2]. In this report, we briefly describe this testing procedure.

Measurement of the gas amplification of ALICE-TRD chambers at the IKF

Before integration in the ALICE experiment, the readout chambers of the ALICE-Transition-RadiationDetector (TRD) [1] are tested at the Institut für Kernphysik Frankfurt (IKF), including measurements of their gas amplification factor. In this report, we describe the revisal of these test-procedures by introducing additional measurements to ensure a self-consistent determination of the absolute g...

Ongoing activities of mass test of the ALICE TRD front end electronics at IKF

Two types of tests are performed for every ROC. Tests via the control engine (CE-tests) are used to check the general functionality of the multi chip modules (MCM). These tests are described in [2]. The experience gained by testing the supermodules 2 to 5 in the year 2007 has been transferred to the tests developing experts and has been used to improve and upgrade single components of the CE-te...

Design and performance of the ALICE TRD front-end electronics

The Transition Radiation Detector (TRD) of the ALICE experiment at CERN incorporates 1.2 million channels which are individually read out and processed. The front-end electronics (FEE) utilizes two custom chips: an 18 channel analog preamplifier and shaper (PASA) and a mixed-signal chip, performing 10 bit analog-to-digital conversion, event buffering and local tracking (TRAP). Both chips togeth...

Beam tests with an ALICE TRD supermodule

The Transition Radiation Detector (TRD) of the ALICE experiment at LHC is designed to provide electron/pion identification and tracking of all charged particles [1]. The TRD will supplement the TPC electron/pion identification by a pion rejection factor of the order of 100 at momenta above 1 GeV/c, allowing precision measurements of quarkonia. Sophisticated on-detector electronics [2] is design...
