This paper presents new developments in Monte Carlo simulation for test beam measurements of a silicon transition radiation detector based on DEPFET—a silicon active pixel detector. The test of DEPFET with fiber radiator has been carried out at the DESY 5 GeV electron beam. Monte Carlo simulation of the test beam setup is based on Geant4. A compari...
Transition Radiation Detectors (TRD) have the attractive feature of being able to separate particles by their gamma factor. Replacing the xenon based gaseous detectors by modern silicon detectors is complicated by the large energy losses of charged particles in 300–700μm of silicon. A silicon active pixel detector—DEPFET—has features which allows a...
The DEPFET pixel detector offers first stage in-pixel amplification by incorporating a field effect transistor in the high resistivity silicon substrate. In this concept, a very small input capacitance can be realized thus allowing for low noise measurements. This makes DEPFET sensors a favorable technology for tracking in particle physics. Therefo...

... For multiple interfaces, interference effects may lead to an increase of the number of maxima and even to a change of the position of the most probable angle, and remove the strong dependence on the -factor. Previous attempts to measure the TR angular distribution were not fully successful because of the limited functionalities of the setups [6][7][8]. In this work, for the first time high precision simultaneous measurements of the TR photon energy and its production angle have been performed. ...

... The latter considerations and moreover the high costs of large detector areas, are two very important reasons, why by far most of today's TRDs are based on gaseous multi-wire proportional chambers (MWPC). But for example also straw tubes are sometimes used, and moreover completely new concepts such as for instance TRDs based on DEPFET sensors were proposed [37]. ...
... The backward compatibility of the DCDB-based DEPFET prototype system in terms of trigger processing and data preparation simplifies its integration into the DEPFET collaboration's existing data acquisition (DAQ) environment [67]. That is a Linux-based software system, implemented using a client/server architecture. ...
