Description
In the context of the Mu3e experiment, High Voltage Monolithic Active Pixel
Sensors (HV-MAPS) are developed as constituents of a highly efficient tracking
detector with good momentum, vertex and timing resolution. The MuPix HV-MAPS prototypes were arranged in a telescope setup
with four layers as an integration test and for efficiency measurements. For high-rate data taking, fast data transfer
is required. Therefore, data transmission via Direct Memory Access (DMA) has been implemented and was tested at a beam test at DESY (Hamburg).
In addition, efficiencies were calculated from straight tracks reconstructed online on a graphics processing unit (GPU).
This talk introduces the readout scheme of the MuPix telescope and focusses on the DMA implementation and the GPU track reconstruction.
