DESY Hamburg operates a test beam facility with three independent beam lines at the DESY II synchrotron. It is world-wide one of very few facilities providing test beams in the GeV range. To this end, it offers electron/positron beams with user-selectable momenta from 1...

Abstract The ATLAS FE-I4 pixel readout chip is a 2 × 2 cm 2 state-of-the-art ASIC that is used in high-energy physics experiments and for research and development purposes. It is optimized for high hit rates and radiation hardness, but it provides only limited charge re...

Abstract 3D technologies are investigated for the upgrade of the ATLAS pixel detector at the HL-LHC. R&D focuses on both, IC design in 3D, as well as on post-processing 3D technologies such as Through Silicon Via (TSV). The first one uses a so-called via first technolog...

We present a pattern recognition method which use datapoints on a plane and estimates the parameters of a circle. MC data are generated in order to test the method's efficiency over noise hits, uncertainty in the hits positions and number of datapoints. The scenario wer...

It is well known that avalanche photodiodes operated in the Geiger mode above the breakdown voltage offer a virtually infinite gain and time accuracy in the picosecond range that can be used for single photon detection. However, their performance in particle detection s...

Abstract The upgrade for the ATLAS detector will have different steps towards HL-LHC. The first upgrade for the Pixel Detector will consist in the construction of a new pixel layer which will be installed during the first shutdown of the LHC machine (foreseen for 2013–2...
