Objectif The measurement of electron-positron pairs in heavy-ion collisions provides the unique opportunity to study the in-medium properties of vector mesons, which is a fundamental issue in modern nuclear, hadron and particle physics. The lepton pair is a "penetrating probe" because it delivers undistorted information on the conditions inside the dense fireball. The Compressed Baryonic Matter (CBM) experiment at the future accelerator facility in Darmstadt will be equipped with a Transition Radiation Tracking detector for electron identification and pion suppression. The challenges in this experiment are the reaction rates of up to 10 MHz and charged particle multiplicities of up to 1000. State-of-the-art X-ray detectors are too slow to be used in these measurements.The goal of this project is to develop the components of a Transition Radiation Tracking detector. The project includes the design and construction of the straw tubes for X-ray detection and the X-ray generating radiator material. The very fast detector response at extremely high reaction rates and particle multiplicities requires the development of fast low-noise readout electronics. Another important task should be the test of the detector prototype components with charged particle beams. The results of the simulations will be documented in a progress report end of 2004. The detector design and the test results will be presented in the technical proposal end of 2005.
