Timing results using an FPGA-based TDC with large arrays of 144 SiPMs

2015

Silicon photomultipliers (SiPMs) have become an alternative to traditional tubes due to several features. However, their implementation to form large arrays is still a challenge especially due to their relatively high intrinsic noise, depending on the chosen readout. In this contribution, two modules composed of SiPMs with an area of roughly mm mm are used in coincidence. Coincidence resolving time (CRT) results with a field-programmable gate array, in combination with a time to digital converter, are shown as a function of both the sensor bias voltage and the digitizer threshold. The dependence of the CRT on the sensor matrix temperature, the amount of SiPM active area and the crystal type…

ATLAS SemiConductor Tracker: operation and performance

2011

The SemiConductor Tracker (SCT) is a silicon strip detector and one of the key precision tracking devices in the Inner Detector of the ATLAS (A Toroidal LHC ApparatuS) experiment at CERN. The SCT installation in the ATLAS experimental cavern was completed in 2007 and it has been operational since then. An extensive commissioning phase followed, during which calibration data was collected and the performance of the system was studied. The SCT was ready for the first LHC proton-proton collisions and it continues recording data successfully since then. In this paper, the current status, operation and performance of the SCT is reviewed, including results from data-taking periods in 2010 and 201…
