A luminosity detector for the PANDA experiment at FAIR
The PANDA experiment at FAIR (Darmstadt) is a fixed target experiment in a high energy storage ring. Antiprotons with a momentum of 1.5 GeV/c up to 15 GeV/c collide with an atomic beam perpendicular to the interaction point (IP). The spectrometer consists of a solenoid magnet around the IP followed by a dipole magnet. The spectrometer stages are both equipped with various planes of detectors for charged and neutral channels. To determine the luminosity with a precision of better than 3%, PANDA will implement a tracking device to reconstruct elastically scattered antiprotons near the non interacting antiproton beam. Four planes equipped with retractable HV-MAPS placed inside vacuum around the beam pipe. In this overview talk we will discuss topics such as cooling of CVD-diamonds used as heat conductors for the active pixel sensors, production of aluminum support frames with stainless steep pipes melted inside, the construction of a differentialy pumped vacuum system, the corresponding feed throughs at the vacuum box and the status of the sensors themselves. All topics are completed by existing prototype results.
