Status of the Front-End-Electronics for the CBM-TRD detector at FAIR — •Dennis Spicker for the CBM collaboration — Institut für Kernphysik, Max von Laue Straße 1, 60438 Frankfurt am Main

At the future Facility for Antiproton and Ion Research (FAIR) the Compressed Baryonic Matter experiment (CBM) is supposed to measure particles from heavy-ion collisions at very high interaction rates. For this purpose, the data acquisition will run in a free-streaming mode without a hierarchical trigger system.

For the Transition Radiation Detector (TRD) the readout system is based on the Self-triggered Pulse Amplification and Digitization ASIC (SPADIC). It features a charge-sensitive amplifier, a continuously sampling ADC, a programmable digital filter and a hit detection logic. The latest version introduces new switchable features such as a low-gain mode, an additional shaping order and digital baseline tracking.

This contribution presents the latest progress towards a final version of the SPADIC chip, as well as a slow-control software framework, including a GUI, that enables the operator to easily configure the SPADIC via the underlying communication protocol "IPbus". The software offers an automated testing routine that helps to assure the quality of the front-end-electronics before installing them on the detectors.
