Abstract 3D silicon sensors, where plasma micromachining is used to etch deep narrow apertures in the silicon substrate to form electrodes of PIN junctions, were successfully manufactured in facilities in Europe and USA. In 2011 the technology underwent a qualification ...

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...

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...

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...

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...
